...problem. The typical symptom there is that one side of the seat won't move, which prevents the whole backrest from going up or down, but you'd detect an obvious twisting to one side.

The backrest-drive motor is right under the front center of the lower cushion, you can see/feel/hear it if you run the lower cushion all the way up.

I think someone with an ISAT/TECH II could pull codes from the seat brainbox (the seat motors on memory seats are not driven directly by the switch, but by the memory control box, which is signaled by the switch) but your problem is somewhere in (a) the brainbox (b) the position sensor (c) the motor (d) the wiring (yeah, lotta help, I know...)

If you have a pick-it-yourself junkyard nearby, all Saab 9000 power seats use the same motors, as noted the memory seats have an extra brainbox (flat black plastic thing with big electrical connector) and a position sensor on each motor output housing (it snaps on, the motors and gearboxes are the same.) The switch and wiring are different on memory seats too, so if you're going to swap anything beyond the motor you want to find a car with memory seats. Earlier cars had memory seats on the passenger side too, and the parts are the same both sides.

My '92 had memory seats on both sides, the '93 Aero interior I bought for it did not. The Aero seats had a bunch of defective mechanicals in them, and the brainbox in the '92 passenger seat was dead. I ended up swapping the '92 passenger-seat mechanicals into the Aero passenger seat, with the '92 driver-seat brainbox, and two of the '92 driver-seat motors into the Aero driver seat. All works fine now, though it was a PITA to get there...and I ended up with Aero seats with memory on both sides.
