my rear demister has stopped working. All the other rear hatch stuff works fine and I checked the fuse and relays. Mirrors are working fine.
I just had a look at the wiring diagrams, and FYI, there is one wire for the demister in BOTH the wiring looms.
(I thought I could pin-point which side it would be before I start looking into the wiring).
I have read just about all the threads mentioning the wiring loom, and one person mentions that the demister is on the right side, another mentions it's on the left side, and now I understand why!
Also here some of the wires which go to each side: (not necessarily all of them)
Power supply antenna
rear right lights
Third brake light
left rear light hatch
motor lock tilgate
switch to external trunk handle
Washer fluid pipe
