the encoder motor is what puts the vehicle in 4wd.

exactly what happens when you command 4wd...? what does the dash switch lights do exactly ?


If the encoder/4wd is defective you should have a service 4wd lt on/flashing , if so what are the failure codes ? you will need a GM specific drive train code reader ..


The encoder does not require any programing, its just a motor..............

with these questions answered then the repairing can begin.
