Chevy avalanche 06
My Chevy avalanche the windows dont roll up. Battery died
when I finally started it again half of the accessories where
out. Right side tail light went out . my gear shift not lighting
up and my gas gage .
Scan it for trouble codes. There's likely some clues there to guide you. I'm assuming that you have a good battery and that all your connections are tight. If in doubt, have the battery load tested and replace it if its bad. Nothing works right on a modern vehicle if there isn't a strong and consistent power source.
