2005 Suburban Service 4WD Light
My 2005 Suburban 4WD isn’t working. When I start the vehicle, all the lights on the selector switch light up, then it goes completely dark. I’ve recently had the encoder motor replaced. I’ve replaced the switch and the TCCM— I was careful to purchase the TCCM with the NPO to match my switch. I checked the ground wires and completely cleaned the ground contacts. None of this has fixed my problem. Any suggestions?
