Service 4WD

RE: Service 4WD
I was talking to one of the tech at the shop I work at, and He said to the switch, because when that switch goes out, that will lock up the transfer case and if you are crusing at 65 down the intestate and that goes out, you are going to be in a world of hurt. I am having him do the switch, and my drivers window on my 2000 silverado ASAP.

RE: Service 4WD
It is probably the selector switch on the dash. I have a 99 Z-71 with 97k miles and have never had the problem but a friend with a 99 4x4 had the same "Service 4WD"issue and his was the switch as so many have atested to. It sounds like the dealer was wanting to run up the bill with his suggestion that it was in the transfer case. Just change the switch and you should be OK.
