Power Seats System Description and Operation
Power Seat System Operation
There are 2 options of power seat systems available in full size trucks. The 6 way driver and passenger power seats, and 8 way driver and passenger power seats with driver memory. For the driver memory seat operation refer to Memory Seats Description and Operation . Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.


( I'm not good at wiring an running an ohm meter.) well then you need to take it to a qualified repair shop.

The motors responsible for moving the seats are not being properly powered. The issue could be due to blown fuse, bad relay, bad connections, bad switches, ad infinitum. In short, any part in between the power source (battery) and the motor is suspect.

Get a hold of the wiring schematic for your car, study it, and get to work.

Sounds like the motor and gearing has worn out, they take a lot of punishment. Replacements are available (sometimes it works out much much cheaper to buy a whole second-hand seat). But that depends how much you like the car...

sounds like you might have a switch problem if the memory for seat position works ok. If you have a multimeter that checks for continuity then you could start there at the switch but you would also need a wiring diagram for the seats

I have a 2007 Impala. Thank you razor67 for the tap. I did not even remove the seat motor. All I used was an 18 inch rod and a hammer from the rear and hit the motor a couple of times and it's freed.

No the adjusters for power seat are made from some steel and a lot of aluminum parts. Replacing the seat tracks are your only option to be safe for they are riveted together

I have the very same problem, no seat heat on either side and no power seat control on the drivers side. anyone know which fuse or switch operates the drivers side power seat? Thanks

I tried pushing in all of the wires under the seat to make sure there were no loose connections. I did not find any but the windows and seat worked after i did that.
