Electric window fault T5 Transporter. My driverside electric window switch unit started packing up a while ago, power to the unit seemed intermittent, sometimes it would work, sometimes not. I took switches apart and cleaned but this did not cure the problem. The electric mirror or passenger (driverside) switch is not working either. Passenger window works, on passenger switch, although is now becoming temperamental.... There appears to be power going to the unit. Any guesses before I have to go to a VW garage and remortgage my house???
