This is for a 92 4 door with the 6-way power seats. The driver's seat will not move forward the full excursion. If you go to the rear, it stops as usual with a small thunk at the end of its travel. Going forward it stops slowly after only a few inches. It does not seem to be hitting anything and does not stop abruptly. It just sort of coasts to a stop. It will repeat this on successive tries. I have raised the seat and looked underneath for any obstruction, but there is none to be found. All other functions of the seat are normal. If I keep going back and forth to test what is going on, eventually neither backward nor forward travel works at all. Letting the thing sit for a while, the mechanism comes to life again leading me to believe the drive motor may be protected internally with a thermal cutout as it is probably only designed for intermittent operation and not the constant operation I impose on it by my back and forth trials. Now, it would be easy to say the motor is bad, but this does not explain why the place where it stops is consistent. Might this be a lubrication issue? Have you run into this problem in your experience? I have the Helm service manual and the unhappy news in that is that the track elements are not replaceable and the whole assembly would have to be replaced. A pricey thought at best. As a happy retiree, I am in that position of having more time than money. I have successfully repaired the window drive motors on all four windows and would not be afraid of tackling the drive motor if that was the problem.
So before I start tearing into this task, advice and direction as well as any warnings would be appreciated.
