My guages have been going crazy and I dont know what to do. The Speed gauge was working but it went haywire last week but its working now. But my Gears and Gas gauge is still bad and not showing accurate. Does anybody know how I can fix this? Or have you had similar problems. This is a 2005 Buick Rendezvous.
i had one like that. had to replace a sensor of some sort on the tranny it had shorted out somehow and made the speedo go wacky. is yours shifting ok? the bad sensor in my tranny also caused shift problems
