My HRW wasnt working on my Xantia and after chacking the relay I decided to check power to the window itself. Power was there.
So I checked the earth wire, nothing, no circuit. So something said to me, remove the panel from off the tailgate. I did this and found the earth wire had burnt out, litleraly into two. It had been chaffing on one ot the metal clips that hold the wiring onto the tailgate and over heated . I big brown/black burn mark was on the paintwork.
I cut the bad wire out and joined together with a 30 amp screw block.
Hey Presto, it works.
I thought I would pass this info on .
