SOURCE: 2005 trailblazer driver seat will not move forward or back.

This kind of issus is almost always the power seat switch is defective.

it sound like you need to replace seat control switch

SOURCE: driver's side front seat won't move

It is likely the gear on the motor came off track with the seat. The seat will have to be removed and bottom panel disassembled.

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.

try tapping the motor that runs the seat back and forth.sometimes the motors get corroded if they are not used often enough.
