Power Seat Wiring

I have a 6 way GM power seat but I am unable to get any movement from the motors. There are three motors, each with two wires. The switches were originally in the armrests on the donor car. I grounded the seat and tried each wire individually to the positive side of the battery but nothing happened.Is there any special way that this is suppose to be wired or does it sound like I have bad motors?

just a guess.
what are you using for the ground?
the seat base may be the ground.
try running a wire from the seat base to the negitive post on a battery, then another wire from one of the wires that opperate the seat. see if anything happens.
i can't imagine you having 3 bad motors.

You said each motor has two wires, One is hot the other is ground. If the motor had one wire then the motor housing would be the ground. It's wired just like elec windows

i wouldn't think that would be the case though because (like i said "i would think"), wouldn't the motor need two wires, one for a forward motion, and one for the reverse?
or does that all have to do with the switch?

Power Seat Wiring

Thanks for the responses. I connected one wire to the negative side of the battery and the other wire to the + side of the battery but got nothing. Also tried each wire one at a time to the + side of the battery and used the seat base as a ground. Still no luck. Sounds like I may have three bad motors.

GM power seat motors (just like power window motors) Reverse power and grounds for direction. Ground one, and power the other. The motor should run in a given direction.

Reverse the polarity and the motor reverses. This is all done in the switches. I would sugest that you go back to the donor car and get the switches with as much of the wiring that is possible.

Power Seat Wiring

Got the switches from the donor car and and ended up with 8 wires. After I connected the six wires to the three motors, the remaining two connect to the battery. Everything is working fine now. Thanks for all the help.
