Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
is this a 1500 truck ?
will the switch show a position of 2WD then what happens when you push 4HI ? will the lights blink ? do you hear any action at all from the drivers side of the transfer case encoder shift motor ?
can you be sure with the key ON that fuse # ***** and # ***** in the inside fuse box show 12 volts on both sides of both fuses testing then in place through the little openings int the tops of them with the key ON ?
how are you making out ?
at this point we have a bad module or bad motor on the transfer case
we need to be sure the transfer case can be shifted into 4HI by hand
can you remove the encoder motor of the transfer case and see if you can shift the transfer case by hand with a small wrench on the stem coming out of the case the encoder motor slides on ?
