I have a 99 silverado. All the lights on 4wd selector switch were off and couldn’t get it to shift. Checked the fuse in engine compartment labeled ATC, and it was good. So I figured it was the switch itself. Decided to work on it on a saturday, and all the dealerships were closed. So I decided to tinker a little and maybe try to reset it by pulling fuse and battery. Before I did I decided to look at the fuse cover of the inside of the truck, and low and behold there was a 15amp fuse labeled 4wd and it was bad. Replaced it and everything is back to normal. CHECK THE FUSES INSIDE AND OUTSIDE BEFORE YOU DO ANYTHING!

I just changed out my switch with a new one. The Service 4WD light is steady on and no lights come up on it. Any suggestions?

Thanks for your instructions. I too was getting the “service 4WD” coming up on the dash. I ordered a replacement on Amazon (less than $40 – non OEM). Seems to have fixed the problem, only time will tell. Thanks for saving me $$$.

The service 4wd light in my 2006 silverado z71 was on, and the indicator lights for 2wd, 4wd, neutral, auto would come on at random. Seemed the truck was in 2wd. I bought a new switch at the dealer, $100, I didn’t want to wait for gmparts.com, paid $25 more, but got it that day, put it in, and the problem seems to be solved. The parts guy said they sell a lot of those switches. BTW, most of the switches I found on ebay were used. I wouldn’t put in a used one !

Okay so I have a 2000 silverado 1500 z71 and my 4×4 panel seems to only stay in 2 HI, I can’t switch it to any other thing. When I start up the truck, only a few of the lights light up. I try pressing others like AWD etc. but the light still is lit up under 2 HI…Is my problem the switch like it is stated here or something major? By the way if it helps it says service 4WD and that comes up after about 5 minutes of driving.

THANKS, it took longer to find the soldering iron than it took to take the switch out and solder three pins and reinstall the switch. So far it is working great. I agree that it sould be a GM recall.

My 2001 Silerado will not transfer from 2WH to 4WH (will not go into 4 whl drive) I push the 4WH button and it just flashes and goes back into 2WH, I took the Switch out of my truck and put in my Tahoe and it worked FINE, so its not the switch, I checked the ATC fuse, it was fine as well, I pulled the wires and cleaned them on the Tran-case, still wont go in the 4WD, any suggestions? PLEASE HELP…Thanks Jon
