Re: Hey guys, need some help with electrical troubleshooting on my 2000 silverado
It does sound like a bad ground. I had a '92 pu that had a bad ground strap between the cab body and the frame at one of the rubber isolators that caused the radio and heater controls to do funky things. Fixed the strap and the problems stopped. Just start checking all of your grounds on the whole truck. Good luck!
