Interesting problem with my driver's seat

[cobrajoe]

I'm having a problem with my driver's seat and I can't figure it out.

The forward and back motor seems to work, but it will only move about 1/5th of the way before it slows down and stops. After that, it sounds like the motor tries to move, but the seat doesn't move. Then, if I wait 5-10 minutes, it will move again.

It seems to me like something is overheating somewhere and the seat moves again when it cools down, but does anyone have any idea where the problem could be?

No. No idea. Never heard of this problem before. Dont search for it cause I am sure its never happened to any Mark before yours.

or you could just tell him the easy way to fix it and then make em smile knowing theres still nice guys out there

There is no spoon. There is no "easy" fix. I am not nice.

I have searched and searched, but found nothing that fixed my problem.

I found the "take apart and clean" post on LOD, and I have taken my motors apart and cleaned them up, but that did not fix the problem. Also, I swapped armatures between two of the motors thinking the problem was a short in the windings, but that didn't work. I've also lubricated the track, but that didn't help either.

I suppose this info might have been helpful in the first post.

Yes, that would have been very helpfull.

The motor cleaning trick is 50/50 if it will work. If a weak motor is pushed too many times it can demagnatize and/or burn windings.

The only fix is to find known working motors or a seat track.

And this will turn out to be a happy ending. with a cost!

I thought burnt windings might be the problem, so I swapped the middle and rear motor armature (forward and back motor and rear tilt motor), and that didn't change the symptoms at all.

I never thought of demagnatizion being a problem. Maybe swapping the motor casings between two of the motors might show a difference.

After swapping the armatures, I wasn't sure if the motors were the problem though. Has anyone experienced any problems with the switches becoming temperamental or the memory module causing problems with the seat movements?

I can get you another seat bottom. Let me know.

 

[cobrajoe]

Thanks, I'll keep that in mind.

There are a couple other things I want to check/test, so if neither work, I'll send you a PM.

There is also a chance that the sensor on the motor that tells the computer where the seat is at is bad. But usually the seat will move to a certain position and not move any further no matter how long you let it rest for.

do the seats have circuit breakers instead of fuses? if yes, maybe the breaker is weak and disconnects,then cools and resets?

The fuse panel lists a circuit breaker as the circuit that runs the power seats. I tried swapping it with the other 20A circuit breaker in the fuse panel, but there wasn't any improvement.

I think I'll check the switch next. There has to be some reason why it seems like it overheats and doesn't move.
