Power driver's seat only travels forward and backward on one side of seat. Other side works fine. Seat does travel up and down properly.

These devices use motors with worm gears to provide the smooth operation and torque necessary to move the seat. The most common problem, other than the motors themselves failing (and since your does move somewhat, the motor is probably OK), the next biggest issue is something gets caught in the gear drive. Get a good look under the seat and see if there isn't something jamming the forward-backward motion of the seat.

Check for a blowin fuse, Defective relay, Loose wires break in one of the wires, Switch could be shot, OR evan the motor has burn,t out,

Before you do any of the expensive things disconnect and reconnect the wiring to the seat I had the same exact problem with my 2009 Chevy Impala and was ready to take it to the dealer when I disconnected the power cables to it and reconnected them I found that one of the Harnesses was loose and the problem was solved

It sounds like it needs a new window regulator.

First try as fallow, get in to the seat, then keep tight your foot on floor and give a good press backward to the seat and operate the seat switch towards back, just release and do it again keep going that way it will start to move back words, if it start to move do it few time and do it every time you get in to the car at least two time per day continue it for one week, It will be OK otherwise need chassis no for more information,

Ck for debri or other objwcts in way of tracks Does it try to move? If so, there is an obstruction, If not trying or no sound when switch is moved, could very well be a fuse or the forward limit switch is being affected by excess forward travel. Move the switch yo back and without kinda help it. if it's trying.

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.

Use a hammer and tap each of the travel rails on seat, this worked great for me, something just gets misaligned in there.

Good day;
What year is you car? Does the other controls work for the seat? and just to clarify the seat won't go forward of back?


Cheers
