MY power seat is broken for my 2004 Impala - 2003 Chevrolet Impala

Hope your trunk is not full! Remove the rear seat. Remove the rear seat back rest. You will now see a shiny black mat, lift that mat up and crawl into the trunk and open the latch from inside.

If the gear is shot then the seat is not going to move you will have to hand wrench it loose. To ensure this is your problem un plug the motor and test the connection with a test light to ensure there is power. If there is you may be able to engage the motor and push the seat forward and back. Good luck this is a pain when the gear is shot or broken, there is no easy fix.

Use a flex head ratchet wrench to remove the seat, or temporary battery to power the seat, non power seat will fit but disabling you side air bag will shut down the whole SRS, and no air bags will work, this is against the law in some states

I work for a factory that makes seats. i know that we send out service parts for broken seats that we have manufactured. you could probably contact a service rep for the make of your car

I also have a 2004 Impala with the same problem. I searched the computer and found that a connection in the wiring under the carpet and behind the passenger seat gets corroded from the floor being wet. I'm in the process of removing seats and carpet to find this problem and hopefully fix it. I'm sure that your door chime quit working too.

you will have to replace the complete assy. the cheapest way is look for a complete wrecking yard seat, or have yours welded at a local machine shop

Should just be 4 bolts holding the seat to the floor, and unplug the wires. Only way to fix it is weld it, or get a different base from an auto wrecker.

It's very likely a broken wire to one of the serveral heating pads in the seat. The next possibility is the heater module which is located under the seat.
When I fixed the heated seat on my Pontiac Bonneville, I just pulled the seat out of the car. The heated seat wires are pretty obvious when you can see under the seat. I had an obvious broken wire that shorted against the seat spring. I repaired that had had resistance in the seat circuit. It turns out that my heater module was also bad. I switched it with the passenger seat and it works fine now. The module is about $80-100.

I have a 2001 impala so this may or may not help but the rear defog relay is on the passenger side dash next to the door Also the rear defog breaker is in the same place.

there are two brackets..one located in the middle of LhH seat and same for RH side. push in on the front of the seat and pull up. it does usually take some preesure to push and pull.
