I have a 1990 Park Ave. All the seat motors work, except the tilt. It will tilt back, but will not come back forward. We are driving with a pillow in our backs because we feel like we are laying in the back seat. How an I make the recliner motor move the seat forward just one time to bring the seat to the upright position?
SOURCE: The driver seat is in the recline position and
I have G35 coupe and it's on a recline position. The car seat won't come up?
SOURCE: The motor on my automatic drivers seat is not
Only if u take the seat out to get at the rising ratchet.Hope this helps.

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.

believe it of not the seats are cable driven there is a series of motors under the seat that have cables attached to them that goes to a series of transmissions, best guess is that the cables are broken that is why you hear the motors and nothing happens, remove the seat and turn it over and you will see the cables.....GOOD LUCK
