I was wonder in anybody had the schematic they could email me. Any help would be greatly appreciated. I am trying to locate a short, keep blowing 30A fuse. One side of terminal shows 12v and the other shows ground, correct me if I am wrong but neither should show ground.
The load side of the 30 amp fuse goes directly to the blower motor control module which is located behind the LH side of the blower motor, under the RH side of the instrument panel.
I had the same thing. Shorted bllower control module. Paid $85 for it at a delco supplier NOT THE DEALER Dealer wanted $170
Got front screw out and loosened 1 of the two rear screws then WIGGLED the module out. GM Manual says loosen both rear screws
WITH WHAT a BLOWTORCH? couldnt get to screw closest to the side of the car.
Check the blower motor too only 3 relatively EAXY screws to remove
the motot costs abt $94 from a delco supplier not a couple hundred the dealer wants
Another forum member sent me the schematics . If you need em let me know.
