I would take it to a certified mechanic the motor is located under the seat and would be a risky job to do your self. hope this was helpful you have a great day.

I just had the same problem. When the seat is powered all the forward, one of the worm drives reached the end of its travel and jammed against the threaded block that it passes through. To fix this the seat has to be unbolted and tipped back. There are four tiny 6mm bolts that hold the motor plate in. Remove these and the motor will come out. The worm drive is bolted in at one end and has a set pin at the other. Remove the worm drive and use a couple of vice grips or equivalent to loosen the threaded block from the worm drive.

Try swapping motors not brushes,maybe the motors are the same just in diffrent positions,it wouldnt be cost effective to have diffrent motors for the same job just diffrent positions,im tipping they will be the same pull seat out or lookcarefully in the car to see

The electric adjustment motor has a drive-gear that engages a gear on the shaft of the adjustment screw (90 degree engagement). The gear on the adjustment shaft looses a tooth. Adjustment motor whines, drive gear on adjustment motor spins, no action though because of missing tooth. A 12mm 1/4" drive socket on a wiggler (universal) on the end of a 6" extension can engage the not on the end of the exposed large adjustment shaft and, as the shaft is lightly loaded and the electrical switch engaged, one can get the shaft to spin almost one revolution at a time until the seat is high enough. It is hard to reach the nut necessary (inside the dull-grey clevis that the shaft threads into) and I had to take off the seat pad by removing the 4@ 13mm nuts (and 3 @10mm nuts holding the center section with the driver's cushion) to more-or-less easily access the situation. Dealership wanted well over $1000. to fix it. Three out of my 4 up and down adjustment motors are running, but don't adjust. PS, on my 2001 Park Avenue on each seat there is one adjustment motor for the front edge up and down, one adjustment motor for the rear edge up and down, one adjustment motor for the seat fore and aft, and one adjustment motor for the sear back tilt. Lots of complication, not so much on durability. We do not swap out drivers and adjust the seats excessively. Weak design on the one internal gear. Manually adjust it, unplug the electric to the motor, Drive happy again.
