How is your battery? How clean are the terminals on it? If the ground is dirty or bad, it can cause alot of weird problems like that.

We own a 2004 gmc yukon that is possessed. sometimes when its started, it puts itself into 4 wheel drive. sometimes 4 high. sometimes 4 low. sometimes the radio looses all its pre programed channels. And sometimes it acts proper. and doesn't do any thing weard. has anyone else experienced this with their vehicle. and does anyone have knowledge on how to fix this possessed behavior. Thank you all for your help. Bob
