Question about 2001 GMC Sierra Crew Cab
I have a 2006 GMC Sierra that i am having a problem with , the voltage gauge goes up to 16 and down to 12, and when u use something ie: windows and hold the button to long everything stops working , have checked battery and alternator , does anyone have the same problem and what can it be , going on a road trip need some answer , and it's colder than ****
If your Sierra has a Duramax, it may be the intake air heater or the fuel heater cycling on and off in the cold weather. But if its pulling the voltage down to 12V after warmup, I would suspect a poor battery. As suggested, get a load test at autozone or ??
