Replaced TCCC & TC motor 4x4 still won't engage
First of all ..Hello and greetings to all, I just joined up here!
My problem started when the 4x4 control selector switch lights went out completely, then one day while backing up the TC engaged hard all by itself, control selector was in 2WD during this. It took me many tries driving forward and reverse while turning switch in and out of auto/4x4H before 4x4 finally disengaged. I suspected the control module went bad so ordered one and also ordered up a TC motor too. I just installed both, cleared any thrown codes and started engine..at first only the 2WD light was on, I switched to other modes and nothing, no blinking light or any 4x4 engagement. For whatever reasoning I disconnected the battery for a few minutes upon re-hooking up power all the lights on the selector switch are lit up now (not normal) and still no operation, TC motor does nothing, any thoughts? 2007 Envoy SLE
