Rear Wiper Mystery S1

[66yostagea]

It happened a few months ago, but cured its self Now it has started again.

When turning the ignition on to start the rear wiper starts and does about a half to one and a half sweeps, then stops randomly. When I turn the ignition off it repeats its self. Stopping randomly.

I checked the switch and definitely in the OFF position.

Any ideas?

My thoughts would be some kind of earth fault.

You could be right Josh. I pulled the wiper fuse from under the dash. The windscreen wipers stopped working but the tailgate kept working.

Also I have a volt meter and it showed only 10 volts with engine not running and went up to13 and a bit with engine going.

I recently rewired my instrument cluster so maybe there is something wrong there.

As said, sounds like an earth problem.
