Is the transfer case on my Silverado 4WD working?
No codes nor “Service 4wd” messages are displayed. There is no clunking or grinding, and the actuator motor sounds as if it is working when the buttons are pushed with ignition on and engine not running. I have been unable to locate any fuse or fuses which might be associated with the transfer case or 4wd system.

Is the service 4WD light on on my GMC Sierra 1500?
4×4 buttons red light is on ,neutral. I had a “Service 4WD” msg pop up out of no where. Looks like it might be the switch based on what I’m reading out here. Wow…quality job #29.
Where are the lights on a Silverado transfer case?
The lights are wired directly to the switch, not to the T-case so throwing the switch lights the light but you don’t know for sure what is actually being commanded of the T-case. They are cheap and very easy to replace. The dash panel it sits in just snaps off, a couple of screws and a connector and you are there.

How many 4WD Motors does a GMC Sierra have?
So in summary, I went through two 4wd Switched, 3 Encoder Motors, had wiring redone from the switch to the transfer case & whatever other part replaced on it, the auto-clutches replaced, a left front wheel speed sensor replaced, and fluids changed.
