My 4x4 hasn't worked since I bought my ZR2...
No lights on the dash and service 4x4 lit up, and the tccm clicks at start up....
Today all the lights are lit up on the buttons, and no service light on cluster, and no click in the rocker panel.... Also the trans won't shift down...not passing gear, not at a stop... Hand shift to down shift...
Got home and unplugged the tccm and now it shifts normally again...
Can anyone tell me what's going on here?
Did the tccm take a crap?
I assumed all this time the encoder was bad (I did change the tccm to one I know worked and still got nothing)
Anybody had this happen?
