2003 Envoy Fuel gage then odometer

[ssylvers]

First I noticed the fuel gauge was regestering way right of full. The next day it seemed ok for a while, then again wrong. I'm not sure if it's right now reading about 1/3 full. Within a day or two following the fuel gauge issue the speedometer started to not be working correctly. I know I'm traveling at least 55 on freeway but the speedometer drops to 45, then slowly moves down to 35 and no matter that I'm speeding up, it does not move. Then the next day, it seems ok!

Does this mean that one part needs replaced or multiple problems?

There is an issue with the stepper motors on the gauge and most likely will need to be replaced. The dealer will try to sell you the whole instrument panel and that's close to $500.00, but most guys that are good with tools will replace the steeper motor there self or take it to a shop to have it done.

You can buy the steeper motor on E-bay for around $15.00 each and they do come with instructions for you to get the job done your self.

Good luck and hope this helps.
