Yes, if you purchase a manual set is will bolt in just the same so long as its the same model and year as they do change from year to year.

you would have to disconnect the motor drive but it isnt like the old days where there were grooves to put the adjuster into, the motor shaft holds the position.

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

I am working on a replacement motor that will come with a new gear/shaft on it. I have one of my setups in the car right now and have the parts for another one ordered. I hope to make a video of the repair in a couple weeks when the parts show up. Still uses plastic gears, but these are larger, more durable gears and the swap is fairly straight forward with just a few modifications.

So here is a diagram of the seat circuitry for your car. Since every other function works except the forward/backward slide function, that leaves basically the forward/backward slide motor, the seat switch, and/or the wiring. If you can verify that the wiring under the seat is in good condition without obstructions, chaffed wires, and/or wires pulled too tight, then it's safe to say it's down to just the motor and/or the switch. Sometimes if the passengers front seat has the same switch, you can plug it in to the drivers' side connector and see what works and what doesn't. If the seat works fine with the other switch, then that's all it needs, if not then it will need a motor. If the other seat doesn't have a switch then you can find them at wrecking yards, or just supply power and ground to the motor in question to see if it works. If it does, then you know you kneed a switch and if not then a motor.
I hope this info helps!~subyguru~

There are 3 electric motors on the seat. One is forward and back, one is front up and down, and one is rear up and down. The switch changes the polarity back and forth to achieve the proper movement. I think the wire color for the forward and back motor is yellow with a white tracer and red with a white tracer. so if the switch gives the motor positive voltage to the yellow with a white tracer and grounds the red with a white tracer the seat moves forward. If the switch gives the red with a white tracer positive and the yellow with a white tracer ground the seat moves back. (or the other way around). So we can safely say it is in the switch.
Good luck and God Bless

I found this post area while looking for a way to fix my stuck 2001 Camry LE drivers seat. Sure enough, while engaging the seat motor (it could be heard making an initial clikc), I hit the front rails a coupel time prettysolidly with a rubber mallet. That fixed it!

Thanks to all for providing a quick fand easy way to get the seat moving again!

Check the fuse box for a blown fuse, both seats may operate on one fuse depending on the model of vehicle and the fuse may be located either under the dash on the drivers side or in the engine compartment on the drivers side.
