Wiring passenger side power seats 2002 chevrolet avalanche

You may have memory seats, your owners manual should have some info on setting memory.
I looked at wiring diagram for your power seat, driver side, it showed three seat motors depending on what your trying to do? If the seat won't move forward and back, have to check horizontal seat motor. The fact that one of the seat motors is working tells me voltage and ground to the seat switch are ok. Could be a seat motor or the control switch problem? I'd have to do testing to decide which?

On the passenger side, under the truck. Up towards the exhaust manifold. Not a fun one to replace on the ground. The plug is up higher at the engine and transmission. Just a note. Both these codes don't usually appear at the same time. If you had recent transmission work done, I would say that the wires are pinched.

have you checked the fuse ?

Maybe this will help Peter. I had to capture it in 2 pics because of screen size. The first one is the top half. The 2nd is the bottom with a bunch of the top included as a repeat.

check fuses and wireing under seat could be a bad seat motor junk yards may have the same seat just got to search around

i have same exact problem in my 2003 suburban , i cant figure it out .

fuel pump relay on the engine side fire wall passenger side. replace that and check fuses. I had the same issue and this fixed it. the ground for the pump is also located on the frame rail by the gas tank. make shure it didnt come loose

The front seats I know will work but as far as the back seats they wont because the shape of the truck..

I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_a3369546f8067589

Probably a loose connection or fuse (start with the fuse and then look for a loose connection in the door)
