Hi Guys:I have an 86 which has really weak power window motors. It is a 3 wire setup to the window motor (+ -, and Ground) To remedy this situation, I got a set of older power window motors off an 1978 A body regal.

These motors use a 2 wire (+ -) system, which flip flops the voltage to make the motor drive the window up and down. I cant find any 1978 regal/ grand prix etc. Door wiring, so I was thinking that a couple relays could probably do the trick. Any suggestions? BR Jerry W

the gn motors are a 2 wire and the drivers door harness has a ground wire that bolts to the door frame. the problem with the gn's is voltage drop, because of 20 year old wiring. you can put a relay in each door for the up position as the down is still fast. getting new motors or the kirban wiring kit won't help too much. the relay will be your best bet unles you rewire the door harnesses.
