Hello! I was browsing and saw this thread about the power seats
. I have a 92 PA ultra and the seats stopped working on me. In our case it was the recline motion that had stopped. I figured there weren't any warranty issues (lol) so we removed the seats and checked it out. What we found was the grease originally put on the guides that is on the runners (the long threaded rod that the seats move on) had hardened, and was jamming the movement of them along the rods. We removed the guides (carefully, there are a few plastic parts on the guide, which over the past 18 years have gotten a bit brittle). We cleaned them out (a few squirts of brake cleaner to dissolve the old grease out), replaced the grease with some Moly, and the seats have been working ever since. We figured the motors must be ok by activating and watching the motor as it was activated. They were working, but the seats weren't. If you are sure the motor is burned, then maybe this doesn't apply, but i thought I would share my experience with the PA seats not functioning properly, and how we got them to work again.
Could it be possible that the motors are failing from the pressure to move the seat that is jammed at the guides? Our motor would get really hot when we activated it while the guides were jammed with old, dried up grease.
Just some experiences
