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?

ck to see if the wires are still connected to the heater under the seat itself , maybe you stuck something under there and broke a wire ,

there is loose contact with the heater wiring

Faulty seat heater pad or seat heater switch.I would first check the switch connections and 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.

15 MILIMETER FOR THE FRONT 11 MILIMETER FOR REAR,UNPLUG ANY WIRES THAT ARE CONNECTED ...LIFT SEAT UP AND OUT.THEIR MIGHT BE A COVER YOU HAVE TO POP OFF IN THE REAR HIDEING 1 OF THE 11 MIL BOLTS

it sounds like the relay in the module for the heated seats that could be going nuts due to a bad wiring connection. most likely a ground.

It is seem funny how i solved the problem,i figure out the cause of the problem because the city i lived in has hi hemuduty and beside the sea(solty weather
)so the heat connection connected by it self.
To solve the problem hit the connection area (swich )by your hand afew times and turn the switch off and on afew times then the problomes had been solved


thank you
