What to do when seat will not come out of a reclining position in a 2000 Buick park avenue?

SOURCE: front seat stays in the reclined postion..

The seat position is changed through the use of a cable that runs through a flexible tunnel, under the seat. In one case that I'm aware of, this cable got stuck around a projecting seat spring under the seat. When the seat was reclined and moved backward or forward, the cable caught on the seat spring and the seat had insufficient slack in the cable to release from the reclined position.

I have the passenger side seat belt which on occassion will lock in the retacted position It has done this twice but I was able to realease the belt moving the strap around. Now nothing I do will release the strap. Is there a mechanical problem I can look at or could there be an electricial issue

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.
