Bought a Williams not long ago and the rear wiper wasn't working. I stripped the motor and mechanism and found it to be seized up with crap. So, I cleaned it up, put it back on and it now works like a charm. The problem is that my front wipers have now gone bezerk. They work but won't return to the off position automaticaly. I'm guessing it's the relay somewhere but I can't undertsand why they were fine before with the rear wiper locked up and now they're buggered.
Any ideas?
