Power Seats Won't Work
After reading all the power seat threads (some helpful info) and then taking the switchs apart and blowing half a dozen fuses I'm stumped. I got the front switch to power the motors and raise and lower the front but cannot get the rear motors to raise the seat. They'll engage to go down but I get nothing when I try to raise them by jumping the switch contacts except a blown fuse. Any way to manually crank the motors? Any other ideas would be appreciated. I'm tired of sitting on the floor.

I have not found a way to manually crank them. But I did have the same problem (seat rear went down but not up) and it was a bad switch. But I wasn't blowing fuses...that would concern me. Sounds almost like the rear motor is fried and grounding out.
IF the rear motor isn't actually fried, you can try this: As a temporary fix I swapped out the control wires from front switch to the rear motor then raised the rear all the way up. Then I put the front switch wires back where they belong and just left the rear switch disconnected so no one will accidentally lower it. BTW I have a new Porsche brand seat motor that i needlessly bought. It was quite expensive but if you're interested maybe we can swing a deal.

Steve, Good idea swapping the wires. I'll give that a try first. If that works I'll look if PP has the new switch. I kept thinking about manually turning the rear gears and may also try to take apart the drive cable going to the rear gears and see if I can rig up a drill to turn them. I've cleaned the switch contacts but think something has happened inside the wiring of the switch to short it out. Thanks for the offer on the motor. I'll get back to you on it.

Did you make any progress on this? I'm having similar issues on my power seats, where they barely worked right after I reconnected the battery on an unrelated repair, and now only the front downards tilt works.
My battery drains pretty fast as well, so i'm wondering if there's a current drain somewhere in my circuit.
