2000 Chevrolet Silverado 1500 Q&A
2000 Chevrolet Silverado 1500 Question: I have a 2000 chevy silverado 4x4, no lights on the selsctor switch?
Is the 4x4 working? Was it scanned with a pro. quality scanner? Not a code reader! - pushrod
NP8 or NR4 RPO code on the glover box label? 3 or 4 button switch assy. The controller is responsible for illuminating the switch indicating the mode your in. As asked B4 does the 4x4 work or not and was it scanned with a real diagnostic monitor, not just an OBII scan tool. The transfer case shift motor is real common with those as well as the transfer case control module. - bad007
