Speedometer Reads High on 2005 Escalade Ext
[The Ultimate Guide to 2003, 2004, 2005 and 2006 Chevrolet / GM Instrument Cluster Problems]
This commodity is an endeavour to bring together in one identify all the knowledge currently available about the common trouble of faulty gauges in 2003, 2004, 2005 and 2006 (plus some early model 2007) GM vehicles. Specifically this article and the problems and solutions outlined here apply to these vehicle models: Silverado, Sierra, Avalanche, Suburban, Yukon, Tahoe, Hummer H2, Escalade, Impala, LeSabre, Rainier, Rendezvous, Cavalier, Kodiak, Malibu, Monte Carlo, SSR, Trailblazer, Venture, Envoy, Topkick, Ascender, Bravada, Silhouette, Aztek, Bonneville, M Am, Grand Prix, Montana, Sunfire.
Common GM Instrument Cluster Issues
Over the years several different problems have surfaced with these GM musical instrument clusters. This department will outline all the most common problems that have been identified.
Private Gauge Problems
The about mutual instrument cluster problem seen on the 03-06 GMs is faulty analog gauges. This is usually the kickoff estimate problem the vehicle owner sees and is experienced every bit a stuck, sticky or jumpy gauge needle. Occasionally the needle will reset itself temporarily later the ignition switch has been turned on and off a few times but before long returns to it's erratic beliefs. In some cases the needle volition "peg out" to the fully counter clock wise or clock wise position. In some cases the needle will move smoothly just will exist reading noticeably higher or lower than normal at all points. This problem typically starts with just one approximate but over time all the analog gauges volition start displaying the same symptoms. Ultimately all gauges will fail if not repaired.
Cause of Private Gauge Problems
Individual gauge bug are almost universally caused by failing gauge motors.Each estimate is controlled by one judge motor called a stepper motor. For case, an instrument cluster with 6 analog gauges volition have 6 stepper motors.
The original stepper motors installed from the factory had an internal material/pattern flaw that acquired curt service life and have since been redesigned several times to increase lifespan and reduce racket.
The current and simply GM authorized replacement is Switec brand, office number X27.168 (this replaces previous part numbers xc5.168, x15.168 and X25.168). These GM stepper motors are not available from GM dealers or retail parts stores such as O'Reilly'due south, Autozone or others. Be aware of generic make stepper motors produced in China, numerous issues take been seen with these aftermarket motors.
Replacement of GM Stepper Motors
GM stepper motors are soldered into identify directly onto the circuit board. Replacement requires de-soldering of the faulty stepper motors for removal and soldering in of the new X27.168 replacement steppers. Feel in electronics de-soldering and soldering is highly suggested if you attempt this repair as impairment to the circuit lath is common with at home repairs.

Digital Display Screen Problems
The adjacent most common problem seen on GM instrument clusters are declining digital displays. This trouble is unrelated to the stepper motor trouble simply is often seen in the same clusters. Virtually GM gauge clusters of this time frame have two digital displays – the odometer and the gear indicator (commonly called the PRNDL screen). Either one or both screen will typically be affected.
This common issue is not actually a problem with the digital displays themselves as they seem to be quite reliable.
4 Most Common Display Problems
1. Dim, Night or Expressionless Brandish
This issue is most often cause by a declining ability supply circuit on the circuit board which requires either replacement components or a solder re-flow. Information technology appears that the circuit board was laid out in a way that caused over heating in certain areas which results in component failure and/or solder articulation failure. Once the articulation or component has failed power to the digital displays is lost causing a expressionless display or power is reduced causing a dim brandish.
2. Language Scrolling Beyond Odometer Screen
In some clusters with the DIC option (Driver'south Information Center) the user has the power to select from several different brandish langues such every bit French, Spanish, etc. The problem seen hither is where the musical instrument cluster randomly scrolls through the dissimilar languages on it'due south own. The use can reset to English simply the cluster will change the linguistic communication randomly or simply curl through the options endlessly.
This problem is virtually commonly seen on Silverado, Sierra, Suburban, Yukon, Avalanche, Tahoe, Escalade and H2.
Causes of Language Scrolling Trouble
Two problems have been identified as potential causes of this problem. I is a faulty selector stalk button on the circuit board which can be replaced with conscientious de-soldering and replacement if a suitable replacement button can be found. The second cause is due to surface insulation resistance failure on the board. Virtually instances can be repaired and this is included as part of the regular rebuild service.
3. Odometer Display On While Vehicle Off – Causing Battery Drain
This problem is typically (simply not always) seen in conjunction with an musical instrument cluster that volition not power on or has been displaying intermittent ability failure. This consequence is oftentimes caused by solder failure and/or surface insulation resistance failure on the circuit board. Most instances can be repaired and this is included as part of the regular rebuild service.
4. Odometer displaying Fault message
This odometer screen issue is seen as the word Fault being displayed on the odometer screen instead of the vehicle's mileage reading. This is a memory chip/software trouble and requires bit replacement and advanced reprogramming to right. I tin can repair this event with our repair service for 03-06 Silverado, Suburban, Sierra, Tahoe, Yukon, Avalanche and Escalade models simply.
Back Lighting Issues
The nighttime time back lighting used in most GM musical instrument clusters of this era are incandescent bulbs which burn out with age, long before the vehicle is taken off the road. The bulbs are soldered directly to the circuit board and replacements are available through specialty supply houses. Alternatively LED bulbs can be installed which offer greater lifespan and are available in diverse colors. LEDs must be 12v rated otherwise resistors will be required.
Battery Drain
Battery drain from the gauge cluster can be caused past phantom warning lights (ABS, high axle indicator, etc) coming on in the gauge cluster even when the vehicle is powered downwardly. Likewise the gauge cluster tin fail to get into "sleep fashion" after shutting down the vehicle as it is designed to do. If the vehicle is not driven for a few days either trouble can drain the battery.Near instances can exist repaired and this is included every bit part of the regular rebuild service.

GM Instrument Cluster Recall / Settlement Information and Vehicle Coverage
The GM Instrument Cluster Settlement was a 2008 class action settlement awarded to owners of certain Full general Motors vehicles with allegedly defective speedometers. The settlement allows the owner or lessee to get their instrument cluster replaced under the terms of a special coverage adjustment to their factory standard warranty.
Background
As early on every bit 2005, the National Highway Traffic Safety Administration had received complaints concerning erratic speedometer and approximate readings from numerous makes and models of GM vehicles.[1] No deaths or injuries were e'er attributed to the erratic gauges, merely owners of the vehicles felt the trouble was a safety concern.
In 2007, Kevin Zwicker filed conform against General Motors in U.S. Commune Court in Seattle seeking three types of compensation:[2]
Replacement of all speedometers on the affected models
Reimbursement for anyone who already paid to have a defective speedometer replaced
Reimbursement for anyone who paid speeding tickets and whose automobile insurance rates rose due to a defective speedometer
John Hall filed a nearly identical suit in U.S. Commune Court in Oregon after paying the out of warranty repair cost to replace the instrument cluster in his 2003 GMC Envoy LE. Both Zwicker and Hall were represented by Beth Terrell, an chaser with the Seattle law firm of Tousley Encephalon Stephens.[ii]
The case was assigned to U.S. District Judge John Coughenour, who decided to certify the lawsuit as a class-activeness.
Terms
If the vehicle is within seven years or seventy,000 miles (110,000 km) of the engagement information technology was first placed in service, GM must replace the instrument panel (parts and labor) for free.
If the vehicle is within vii years and between 70,001 miles (110,001 km) and lxxx,000 miles (130,000 km) of the engagement it was first placed in service, GM must replace the musical instrument panel (parts) for free. Any labor costs will be the responsibility of the vehicle owner.
Owners who paid for repairs to the speedometer before the class activity settlement are eligible for reimbursement under the following terms:
If the speedometer failed and the vehicle is inside 7 years had less than seventy,000 miles on it, upon proper proof of claim GM will reimburse the toll of repairs (parts and labor) upward to the limit of what a GM dealership would take charged.
If the speedometer failed and the vehicle is inside 7 years and had more than than 70,000 miles simply less than eighty,000 miles on it, upon proper proof of claim GM will reimburse the price of the part only (no labor).

GM Instrument Cluster Repair and Replacement Options
Several options be for repair and/or replacement of faulty GM instrument clusters, this section will outline these options.
Replacement or Repair By GM Dealership
GM dealers do non offer repair of electronics just they do offer replacement. However, no newly manufactured replacement instrument clusters exist any longer for 03-06 GM vehicles. GM will replace instrument clusters with used musical instrument clusters that have been rebuilt when a replacement is required. They then send your old instrument cluster to their tertiary party repair partner to be rebuilt and sold to the next customer needing it. Because they are replacing your entire instrument cluster with a different unit they must re-program the replacement unit of measurement so that your odometer mileage volition display correctly. (GM vehicle mileage is stored inside the instrument cluster, non in the vehicle computer.) Because of this re-progaming and labor to remove/re-install this option is the most expensive.
Purchase a New Gauge Cluster
As mentioned no truly new instrument clusters are produced any longer for these 03-06 GM vehicles. So any instrument cluster being sold now is a used unit or a rebuilt used unit.
Purchase a Used Musical instrument Cluster
Used instrument clusters are typically available at any number of save yards simply there are several issues with this solution. First, whatever used instrument cluster will have the older generation of stepper motors and is likely to have failing gauges at the time of purchase. Salvage yards can't fully examination instrument clusters and typically electronics are sold "Every bit Is" making a return/refund unlikely. 2nd, when you lot install a used instrument cluster information technology's odometer will display the mileage from the vehicle it came out of, not your vehicle'south mileage. This requires a trip to the dealer for mileage re-programming.
DIY Repair of GM Musical instrument Cluster
At home repair is possible in some cases simply requires feel with fragile circuit lath component de-soldering and soldering. It's not recommended to attempt these kinds of repairs without previous feel every bit damage to the electronics is common. This can require replacement of the whole instrument cluster costing more than than a professional person repair would have in the first identify. See links in the resources department for DIY repair information and parts links.

Considering of the large number of vehicles effected several GM musical instrument cluster repair specialists take become available who specialize in the repair of GM instrument clusters. Services range from unmarried judge repairs to fully warrantied consummate rebuild services. Nationwide aircraft allows for quick turn around limiting vehicle downward fourth dimension. Equally with any service purchase the customers is encouraged to do his/her due diligence and research the service provider fully, reading customer reviews if bachelor and verifying reputation online.
Instrument Cluster Removal From Vehicle
GM instrument cluster removal is pretty directly forward on well-nigh GMs of this era. The basic procedure is to simply remove the plastic trim panels that surround the cluster, they typically pop off although some volition take 1/iv″ screws in diverse locations but all can be located by eye with a careful inspection. Next the cluster itself volition be held in with several 1/4″ screws. And finally there will exist 1 or 2 wire harness plugs in the back that need to exist simply unplugged. Now the cluster can be removed for replacement or repair. Click here for a .pdf showing all the individual steps to remove virtually GM musical instrument clusters.
Common Questions and Bug
This section outlines the common questions and issues with individual gauges and is written specifically for Silverados just these issues are common to about all GMs of this era listed in the beginning of this article.
Silverado gas gauge bug – Silverado gas approximate recall – Silverado gas gauge not working – Silverado fuel gauge problems – Silverado fuel approximate erratic – Silverado fuel gauge goes to empty
GMs of this era besides endure from faulty fuel level sending units inside the fuel tank, this is a very common problem just like fuel gauges non working. If your gas gauge is the only approximate not working it's recommended to diagnose the fuel level sending unit first as a possible cause of faulty fuel level readings on the gas guess. This sending unit is part of the larger fuel pump assembly. If the sending unit checks out then you know the gas guess is bad and needs rebuilt. However, if yous take a bad gas gauge and also other musical instrument cluster issues you may adopt to have the instrument cluster fully rebuilt commencement and become from there.
Here's a link to Amazon where y'all tin can purchase fuel pump assemblies, make sure you check to brand sure information technology fits your vehicle earlier y'all buy. Silverado Fuel Pump Assembly
Silverado oil pressure estimate pegged – Silverado oil pressure approximate fluctuations – Silverado oil pressure level gauge high
If your 2003, 2004, 2005 or 2006 Silverado oil force per unit area gauge pegged out, has unusual fluctuations in it's readings or reads high it can be caused by i of two problems. The showtime common crusade is a faulty oil pressure level sensor which is mounted on the engine. This is still some other mutual issue with 03-06 Silverados. Replacement sensors are fairly inexpensive and are widely available online. If your oil pressure level approximate is the simply approximate not working it's recommended to diagnose the oil pressure sending unit offset as a possible cause of oil pressure gauge fluctuations. If the oil pressure sending unit checks out then you know the oil pressure gauge is bad and needs rebuilt. All the same, if you lot have a bad oil force per unit area judge and also other instrument cluster problems you may prefer to accept the instrument cluster fully rebuilt first and go from at that place.
Hither's a link to Amazon where yous can buy an oil pressure sensor, make sure yous check to make sure it fits your vehicle before y'all buy. Silverado Oil Pressure level Sensor
Silverado speedometer problems – Silverado speedometer repair -Silverado speedometer repair kit – Silverado speedometer recall
Silverado speedometer problems are some of the most common ones reported as speedometer problems are pretty difficult to ignore or piece of work around. You might be curious if your Silverado speedometer problems may be caused by a faulty speed sensor or speedometer cable. Since these instrument clusters are fully electronic there is no traditional speedometer cablevision as there used to be in older vehicles so that rules that out. The speed sensors in modernistic vehicles are actually very reliable and rarely get out, merely it is possible. So equally a test to know if your speed sensor may be the cause of your speedometer issues you simply need to pay attention to how your automatic manual is behaving. The auto tranny depends on the signal from the speed sensor to make up one's mind shift points and shift hardness so if your tranny is even so shifting like normal you tin can be sure your speed sensor is not the cause of any speedometer gauge problems yous've observed. Ruling out the speed sensor you lot can exist sure yous need speedometer repair to gear up the issue. If you have experience soldering electronics Silverado speedometer repair kits are available online for some models – see link in resources department beneath.
Silverado tachometer problem – Silverado tachometer quit working
If your Silverado tachometer quit working y'all can be certain that the cause is a bad gauge in the instrument cluster acquired past a failing stepper motor.
Silverado voltage approximate – Silverado voltage driblet – Silverado voltage fluctuation
If you take voltage gauge fluctuation bug or you've seen your voltage is drop with no other sign of battery drain or alternator issues then you can be certain that your voltage gauge has a failing stepper motor and volition demand gauge repair.
Silverado temp judge non working – Silverado temp gauge up and downward
If yous have a temp gauge not working or reading up and down you should first make certain y'all have plenty of coolant in your radiator of course but baring that the but probable crusade on a Silverado would be a failing stepper motor on the temperature gauge which requires gauge repair.
Silverado transmission temperature gauge
Silverado 2500, 3500 and 1500HD models got a manufactory transmission temperature gauge from the factory while all other models did not. The manual temperature gauge suffers from the same tendency to fail as all the other gauges and again volition be caused by a failing stepper motor. Light duty trucks can be upgraded with a transmission temperature judge if you want to monitor your transmission temps during towing or hauling. At that place are two ways to accomplish this. First you tin install an instrument cluster out of a truck that has the trans temp gauge and it will be fully functional in your vehicle because all Silverados (as well as Suburbans, Sierras, Tahoes, Avalanches) came pre-wired and have a temp sensor already installed in the transmission right from the factory. This solution will require the replacement musical instrument cluster to exist re-programmed so that the odometer displays your vehicles mileage instead of the vehicle the cluster came out of. The mileage is stored within each clusters retention not in the vehicles computer.The second and maybe better selection is to have a mill transmission temperature gauge installed into your original instrument cluster. This can be done during other repair work to the cluster or as a stand solitary upgrade. Re-programming of the instrument cluster is necessary to make the new approximate functional and should be included as part of the gauge upgrade service. Because of this at dwelling installation of a factory trans temp gauge is not feasible.
Can I notwithstanding drive my vehicle while the musical instrument cluster is out for repair?
Yes, GM vehicles of this generation will notwithstanding start and run similar normal with the instrument cluster removed and it volition not harm the vehicle or the gauge cluster in any way.
How much does it price to have a GM musical instrument cluster repaired?
Dealers typically charge anywhere from $500-$1,000 for the total task including parts, labor and programming. Instrument cluster repair specialists unremarkably range from $150-$250 for a full rebuild and $fifty-150 for a single gauge repair. Prices vary depending on exactly what services are performed (light replacement, display repair, power failure repair,etc) and whether aircraft is involved.
Does my approximate cluster have to be re-programmed when it'southward repaired?
If you take your gauge cluster rebuilt it will not need to be re-programmed. However, if you lot replace your original guess cluster with some other one and so that i will need to be re-programmed otherwise it's odometer display will read incorrectly. It will read the mileage of the vehicle that that gauge cluster was taken from. The odometer reading is stored inside the instrument cluster not the vehicle's computer.
