Question about 2001 Buick Park Avenue
Are you sure you need to replace the motor in it? test the motor right on the spot with some test wires first.

Take apart the drive box in front of seat track, on both sides with an allen wrench. You can then push the seat to get at the bolts to remove it. My trolley drive motor had bad brushes. I am now looking to replace the motor, if I can find the replacement.

I had the same problem on my 2003 Toyota Camry. The threaded drive screws are what spin underneath the seat and cause the seat to move back and forth (same way a garage door opens or closes). When the seat gets all the way in the forward position, the threading on the drive screws ends, which causes the bolts connected to the seat to jam and get stuck. It should sound like the motor is trying to turn but it won't, it just clicks. Un-jam the bolts and rotate them one rotation from the all the way forward position to ensure your seat is reinstalled straight.

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 [email protected] 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.
