Outer Limits 4x4 Board

I am trouble shooting some electrical probs on a friends GQ tomorrow.

All is pretty normal except the rear window wiper is on all the time.

Is there a common cause for this or will I need to trouble shoot it all the way to chase the problem down.

Cheers

They are a bastard to trouble shoot.

I had a problem with mine (wouldn't turn on) years ago. I ended up rewiring it from the motor back to the stalk.

Was heaps easier than trying to find where the fault was.

yeah i have the same prob. atm i turn it on and it doesnt turn off??
