2002 Chevy Impala - Stuck Driver's Power Seat Sign In

I have a 2002 Chevy Impala with power driver's seat. The seat has three motors which move the seat forward/back, front of the seat up/down, rear of the seat up/down.

The seat will no longer go up/down in the rear of the seat. More importantly, it will no longer go forward or back. The seat traverses forward and back along two "jack screws", one mounted on each side of the seat. The left side jack screw spins and wants to move the seat forward or back but eventually stops when it can no longer go any further because the right side jack screw will not turn at all.

All of the motors are working properly and turning the flexible drive shafts. The drive shafts do not appear to be stripped at the ends. After removing the drive shaft covers and reinstalling the drive shaft, I can see that they are turning when the motors are activated.

I then removed the drive shafts and inserted a square bit into the end where the drive shaft gets inserted into the gearing attached to the jack screw. The bit just spins and spins and doesn’t turn the jack screw.

I cannot removed the seat because it is in a position where the rear bolts are covered by the seat. I have tried to remove the four bolts under the seat that attach the seat to the frame. I am unable to break these bolts free (they appear to be welded or secured with loc-tite).

Any help/ideas would be greatly appreciated. I would like to get my seat fully functional again.

They really don't sell any new replacement parts for these. You are probably better off to go buy a used seat frame.

The seat is not welded or locktighted in. It will come out if you are trying in the right place.
