It's sounds like some kind of wiring issue. I know I've read on many forums and watched a lot of YouTube videos that say a ground wire on the firewall can cause really weird stuff to happen. If you're standing in front of your yukon it is almost dead center in the middle like right behind your engine cover. You will definitely need a flashlight and something to stand on to get to it. I will try to find a video and post it so you know exactly where to look.


Here's a good video and it will only take you a couple of minutes to do.
