Hi all. My rear wiper wasn't working when i bought my E36 Touring last week (but the washer jet works fine). So I finally got round to having a look just now. The white wire that should run throught the rubber pipe at the top of the boot opening was snapped, so I joined it back together. Still no power. I've traced it down to behind the light cluster, and it's also broken there. But i can't see where it was joined to.
I traced the wires attached to the rear wiper motor: A brown, a red and yellow, a purple and black stripe, and a green and blue(ithink) stripe. These all run to behind the light cluster along with the white one.I found two wires disconnected, plugged them together but then the rear wiper came on and stayed on even with the ignition off. this also happened when i connected the white wire to the power cable.
Can anyone tell me where i'm going wrong?
