Report: Speedometer not reading or not reading mileage stuck on 60,30 etc.
Cadillac Escalade Problem
Model Year Affected: 2005
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault.
Currently my speedometer starting being stuck on misc. speeds when I would get the truck before I even started it up it would be on like 30mph, I think ok maybe its stuck...well it continued to get worse it would be stuck on 70 then as I drove it was clocking the speed when I stop its still on 70mph. I discovered that it is a common problem in GM automobiles and the stepper motor has to be replaced. A stepper motor is basically a small part that cost $5-$30 depending where you shop, but it controls the needle on the speedometer and the other gauges in the instrument cluster, i.e the fuel,oil,engine temp readings. Many places when charge you upwards of at least $150 to fix, some want you to removed the whole instrument cluster from your automobile and mail it to them so they repair and you pay online, however...I saw a video on YouTube DIY and was successful in repairing it myself. All you need is a fork (yes the one you eat with),soldering iron,de-solder wick,core resin for electronics,and the stepper motor to replace the bad one in the truck. I advise to search Youtube for the video you should be able to find it by entering: GM speedometer and you will see a video of a repair on a Chevy Sierra but basically majority of all GM cars repair the same way...I spent $30 totally to fix it.
