I have been trying to fix my electric seats - Disco 96 ES. I have exposed all the wiring harnesses, checked all the fuses and relays (under passenger seat), applied external power to the seats and they work in every direction. I have dismantled the switches, cleaned the contacts and made sure they work on another Disco. The drivers side works once after disconnecting the switch and reconnecting it - so I can adjust the drivers seat by connecting and disconnecting every time! The passenger seat won't work at all. All the relevent points on the switch on the passenger side show they have power running to them. I understand there is no ECU for the seats??? This seems to be one of those weird wiring mysteries. Any further ideas from forum members would be gratefully recieved!
