Why are my speedometers all failing at the same time?
This problem typically starts with just one gauge but over time all the analog gauges will start displaying the same symptoms. Ultimately all gauges will fail if not repaired. Individual gauge problems are almost universally caused by failing gauge motors. Each gauge is controlled by one gauge motor called a stepper motor.
How often does a GM stepper motor fail?
If we have a stepper motor fail it is maybe 1 in 10,000. x27.168 motors are the same motors that authorized GM Servive Centers use. BEWARE! Other shops sell and use other motors by other manufacturers that claim to have an improved design. We remove these motors from instrument panels daily.
Is there a recall on the GM Silverado speedometer?
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 General Motors vehicles with allegedly defective speedometers.
How to repair GM instrument cluster you speedometer?

Why is my speedometer stuck on my GM Silverado?
This section will outline all the most common problems that have been identified. The most common instrument cluster problem seen on the 03-06 GMs is faulty analog gauges. This is usually the first gauge problem the vehicle owner sees and is experienced as a stuck, sticky or jumpy gauge needle.
Where can I buy stepper motors for my Chevy Silverado?
These GM stepper motors are not available from GM dealers or retail parts stores such as O’Reilly’s, Autozone or others. Be aware of generic brand stepper motors produced in China, numerous problems have been seen with these aftermarket motors.
What kind of display does a GM speedometer have?
Most 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. 1. Dim, Dark or Dead Display
Are there any accidents due to erratic speedometers?
No deaths or injuries were ever attributed to the erratic gauges, but owners of the vehicles felt the problem was a safety concern. In 2007, Kevin Zwicker filed suit against General Motors in U.S. District Court in Seattle seeking three types of compensation:
This problem typically starts with just one gauge but over time all the analog gauges will start displaying the same symptoms. Ultimately all gauges will fail if not repaired. Individual gauge problems are almost universally caused by failing gauge motors. Each gauge is controlled by one gauge motor called a stepper motor.
Why are the lights on my instrument cluster not working?
2006 infiniti qx56 – rpm not working, some of the dash lights not lit, when I turn headlights on or day light running lights on the entire instrument cluster goes black. when turned off, the dash is lit (except for the ones that don’t lite at all). do I need a new cluster?
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 General Motors vehicles with allegedly defective speedometers.
How does a fuel pump work on a gas gauge?
The fuel pump module includes the fuel sending unit, used by the gas gauge to detect and display fuel level. https://www.flickr.com/photos/3ndymion/33556245572. The gas gauge is a relatively simple circuit, but its simplicity means each component is essential to its function.
What do I do if my gas gauge is not working?
In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.
Where is the speedometer sensor on a car?
The speedometer sensor is located inside the transmission and attached to a driveshaft, which impacts multiple functions of the car. Due to this fact, it’s possible that the Check Engine Light will light up on the dashboard if a sensor problem is discovered by the vehicle’s CPU.
Why is my transmission temperature not working on my Silverado?
Silverado 2500, 3500 and 1500HD models got a factory transmission temperature gauge from the factory while all other models did not. The transmission temperature gauge suffers from the same tendency to fail as all the other gauges and again will be caused by a failing stepper motor.
How can I test a faulty fuel gauge?
One final test you can run is to remove the sender from the tank and connect it to an ohmmeter. One lead goes to the sender terminal and the other connects to the sender housing. Once you have it hooked up simply move the float arm and check the resistance measured by the meter.
How does a fuel gauge work on a boat?
On older vehicles or boats, the fuel gauge will usually have 2 terminals. One of these terminals receives 12V of power when the ignition is turned on. The other terminal is the sending wire from the sending unit. The gauge itself is then grounded.
Where is the sender on a fuel gauge?
There are basically two components to any fuel gauge. There is the sender which is located in the tank and then the visible gauge that rests within your instrument panel. The sender is made up of a float on an arm that changes the resistance the sender applies to a circuit depending on the fuel level.
