service 4wd light on a 2001 silverado....please he
I have a 2001 Silverado, I drove home in 4wd last night and left the truck in 4x4 all night (the temp is -5) well I get out there today (still -5) and my service 4wd light is on, and my truck is back in 2wd! I went to the dealer and purchased a new switch, well no luck. All the lights are still out, and it still doesn稚 work. The fuse is good, and i wiggled the wires around to see if I could get it to work for a min. nothing!
Is there any chance something is frozen, or perhaps ice hit a plug and unplugged something on the transfer case?
I went to AutoZone to see if they could erase the code and clear the light. It didn稚 work, no code showed up.

I am pretty sure that the actual mechanism that engages the front axle is vacuum operated. I do not remember where the connectors are but I would suspect that the hoses that go to the front axle are broke or frozen. Kinda hard to fix at -5.
