My tahoe got stuck in 4WD and my mechanic has to change a part in the
system. My 4WD light stayed on all the time. I won’t get the truck back
til next week. Your not the only on with the problem. I don’t know how
much its going to cost yet.

The problem is not so unusual with these electric switch driven 4WD
systems. This goes for all manufacturers. Oh for the old manual
locking hubs and transfer case lever. At least they always worked.

I HAVE THE SAME PROBLEM WITH MY 2000 SILVERADO. IT ONLY HAS 6000 MILES
ON IT. I HAVE USED THE 4 WHEEL DRIVE MAYBE A HALF DOZEN TIMES IN SNOW
GETTING IN AND OUT OF MY DRIVEWAY. I BOUGHT THE VEHICLE NEW. THE
LIGHTS WON T COME ON IN 4 WHEEL HIGH OR LOW RANGE. MESSAGE IN MESSAGE
CENTER SAYS SERVICE 4 WHEEL DRIVE. OWNERS MANUAL SAYS TAKE TO DEALER
FOR REPAIRS WHICH I DON T WANT TO DO. 4 WHEEL DRIVE FUSE IS OK. ANY

I have a 00 4×4 Silverado too, 64,000 miles now…
My service 4×4 light came on too, 2.5 years ago…..
Problem was cold solder joints in the 4×4 push button
switches on the dash…. Warranty covered problem.
4 button switch replacement…. Either buy the $50
button switch or resolder the switch ‘bad’ wire joints.

I would LOVE to have manual lock ins on a 99 Jimmy, or even a full time
transfer case like the 77 trucks did

Sounds like the encoder motor took a c*** on ya. be glad it wasnt the
control module (under dash right side behind kick panel) thats about a 500
part from GM. Good luck finding someone with that part used.

This could be a long shot, but on my 99 Jimmy, there is a Vaccum switch for
the front end under neath the battery, and the vaccum line running to it
could have gotten melted or broken or somthing, never know. I would check
the vaccum to it before taking to a dealer.
