Hi......and help!
I have a trusty 1993 TDi Range Rover whose front windows have just packed up within a couple of days of each other......which is ideal in this hot weather! The rear ones work without a problem. I've switched over the switches and the relays between front and rear (no difference).
Could it be the window lift ECU or would this just pack up completely?
Cheers
Rich
