Best to you.

Driver door or seat module. All of these components are controlled by s module. You'll need a scan tool to properly diagnose.

Beings it's probably a electric adjusted seat (you didn't state if so), it might be a fuse.

Have you checked the fuse? Look in owners manual for the fuse block and see if the fuse is burnt.

If you have the owners manual, you can find what you are looking for under fuse panels in the appendix, It will show you where the fuse panel is located, and where you can find the fuse in it. If you don't have a manual, you can probably find it at autozone.com. simply put in your vehicle info in,under the repair guide section. you also may want to check the connector under the seat, its possible someone may have accidently disconnected it with a foot, or something that was under the seat. inspect the harness for damage, it may have been pinched while moving the seat.If you have more than one power seat,and the others are functioning,it is likely to be the seat control switch,wiring harness,or motor. there also may be something wedged in the mechanisms that move the seat.more than likely your fuse panel will be under the dash, on the drivers side,or in the end of the dashboard,visisble when the door is open on the drivers side. hope this helps!

it sounds like the driver seat module. It controls all of these items.

try reprogramming the seats had to do this on an infiniti. look in the owners manual for the seat adjustments and it should tell you how to reprogram the auto seat. on this one i had to open the door more than two times turn key to on position not started set the seats and everything where it needed to be and resave it on the door switch. then the seat starting working right again.

sounds like a bad fuse, have a look at your manual and see which fuse controls those parts, they are most likely on the same fuse, the fuse box may also say which fuse is for what, If the fuse in the first box doesn't fix it, try a new fuse in the box under the hood, let me know how this goes, you may also have corrosion in a wire but check the fuses first.
