in the down (back) and forward position (seat). I did a search and there is not a real solution for my problem. I disassembled and cleaned the switch with no luck. I believe it is the switch because the motors were working but, in only one direction...I will order a new seat switch but, if that does not work, the only other way is to remove the seat. The problem is, I can not get to the front bolts since they are covered by the seat. Anybody has suggestions for a cure or how to remove the seat...?

You can jump the seat swith motors by touching the contacts at the motors on the power and ground if the switch is bad.

You can use a 12 volt cordless drill batter with wires attached to power and ground of the battery and jump them to the power and ground on the seat motors.

Just play with them till you get it moving the right way, then you can access your seat hold down bolts.

Sometimes I have had motors jam up, and the solution was to push alot of my body weight in the direction that I was intending to move the seat.

I do have a question though, Have you checked all the fuses?
Check for wear marks on the fuses, you may need to replace them if contacts are worn.

I did check all the fuses. The passenger's seat is working just fine. I just got the new switch and...it did not solve the problem!
It is going to be difficult to reach the seat motors since the seat stuck all the way forward and the back rest rest all the way back...Picture that in your mind. I am not a contorsionist so I may have to use all my weight and move in the same direction I want the seat to go...Hopefully, it will work...

It was a bi**** to get to the front bolts but, I did it. It is late and dark, tomorrow morning will take a look and troubleshoot the seat electrical components.
Any tips/sugggestions...?

I took the seat out and now I bench tested all the motor and they are working fine...after disconnecting the memory seat control unit under the seat. Since everything connects to this part...by the method of elimination, it all points to this control unit. The part number is: 124 820 00 26. By the way, if you do search in Fast lane, the part number will bring the seat switch and a pump. They are not the correct part...
Does anybody know how to test it...or have one lying around you want to sell...?
The saga continues...
