Go a 99 Silverado that I lost the 4wd on a couple of weeks ago. Had 4 high going and decided hit the button for 4 low. It tried switching over and then the service 4wd light came on. Still got 2wd. Anyone one got any ideas where I need to start looking to try and fix this? Truck is stuck in the snow and ice along side the garage and getting the 4wd bak will go a long ways to me getting out of there.
Thanks
