Seat adjustments not working

Unread post by Isola »

Hello,

Any idea what could make the front seat adjustments and the steering wheel adjustments not working?

So far I've checked all the fuses in the boot. There's one 30 A fuse for each front seat plus a smaller fuse for the seat ECU. I've also checked all the connectors below the front seats and, just to be sure, also those below the rear seat cushion. Everything seems to be ok, but the seats don't move.

Where's a driving position ECU located? I think I've read somewhere it should be below the rear seat, but that's not the case.

Check if the relay in the trunk is clicking to wake up the seats. If not and the relay is ok than you have a broken cable from the connector in the left side trunk ecu. The relay is operated via that ecu.

Thanks. I forgot to follow this board for months. The cause was a cut wire that energized the relay R21 in the fuse box in the boot. I really cannot understand how the wire has been damaged. It was simply cut only an inch or so from the ECU connector. The ECU is located at the left-hand side of the boot.
