Why is my four wheel drive not working?
I have replaced the indicator(Push Buttons) and the TCCM. The fuses are fine. I also have no "Service 4wd" message either. So at this point I have no idea whats wrong with it. Someone told me some kind of sensor or sensors but I dont know what specific sensors they were talking about
2000 Silverado 2500 V8 6.0L
Their is no lights on the indicator either
Basically no power to anything thats 4wd

How often have you used the 4? Has it ever been serviced? You need a transmission mechanic to inspect it.

If it's like the Chevy 4x4 I used to own, the front drive train is engaged by an actuator that heats up and expands, depressing a lever and engaging the front differential. That may be faulty.

Do a search on youtube for info or find a mechanic that knows the system.
