You need to run an earth wire from the wiper motor mounting to the car body.

There is an earth under the dash somewhere that corrodes and causes the problem,but I have found that running an independant earth to the motor works just as well to fix the problem and I am yet to have any further problems with repairing one this way.

Good luck and let us know how you get on.

I'd rather push my Alfa than drive a BMW....
