I have a 2005 avalanche that locks itself into 4 wheel low on some starts and wont come out of it unless i wack the transfer case motor, sounds simple enough but I cant figure out if its in 2wd when I shut the truck off what is making it go into 4 low when the truck is restarted.If its the push buttons why do I have to wack the motor?
