My instrument cluster went from working partime to not at all.the gauges were going up and down and all the idiot lights are on.the power windows and door locks,stereo and the a/c do not work.i un pluged the instrument cluster to see if every thing would work and it did not.do I have another issue somewhere?
GM had bad stepper motors inside the instrument cluster,2003 to 2006 . These stepper motors control the gauge needles . Sounds like you have a few different problems . Instrument cluster has nothing to do with the A/C , radio , windows , locks . One possibility mite be that they all share a common ground . Do you know what wiring diagrams are ? How to read an use one ,along with a DVOM - digital volt ohm meter to test automotive electrical circuit's ?

Sounds as though u have experience the GM usual cluster failure. They go bad more often then probably any other vehicle. Gm has been replacing some under a goodwill warranty for some customers.

I have a 2007 GMC Yukon and all of the guages (speed, oil, battery, etc.) recently stopped working for no apparent reason. The backlight still works but the guages do not. Could this be something as simple as a fuse? What should I do?
