I have had my P38 99 for some weeks, and I try to fix some stange electrical problems. First of all: When I push the break pedal, the rear wiper starts! When the pedal is released, the wiper stops. I have checkt upper tailgat, but everything is ok there. Were is the fault?

I agree with Mozz above.....they can be a bit trying...but that's why we love them!!

Sounds like you have a major earth leakage somewhere....

My first thing would be to strip the rear light clusters and check the wiring to them.

After that check the fuse box under the bonnet, they have been known to burn out and cause weird electrical issues.....maybe power is tracking across some corroded contacts on there!

Then, if they all are clean and sound, I'd be tracing the wiring to the wiper motor, maybe someone had issues and have (badly) re-wired it, and took a power feed from the brake light circuit!

Good luck!

My tuppence worth ! I have been having weird electrical and alarm faults ! think I have now traced it to the electrical multi plug behind the kick panel in front passenger seat footwell caused by a caused by blocked drainage pipes forcing causing dampness and corrosion ! Welcome to the nut house

You aren't in reverse when this happens by any chance are you?
