W126 power seat problem, 560 SEL

[LandYaghtLover]

My passenger seat is not working right. More than that, it keep running. On the advise here I took apart the switches. They looked new and clean. I cleaned them anyway and made sure none of the ball bearing came out, etc. After doing so. Same issue, which is:

Head rest intermittent, but usually works.

Back rest tilt works fine 100%

Front edge of seat up/down works 100%

Back edge of seat up/down - no go

Forward/back motion - no go

Weird: One motor, either rear up/down or the forward/back function keeps trying to operate for a second or two, then stops, then repeats over and over. I can see the cable tension up. Also when trying to operate the rear up/down I can see a cable tension. Its like the seat wants to move, but can not. Next I will lube the tracks (again). But my concern is the endless loop on of the motors is doing.

If it helps, memory seating is a no-go too. Although I never tried it with the passenger seat hooked-up in its endless loop issue. I will do so.

BTW, you have NO idea how much "fun" it is to remove one of these seats when the back is all the way down and the seat is all the way back!
