I'm pretty sure that the UCH takes care of controlling the wipers,there are no relays as such.I'd look for water ingress around the are of the UCH or possibly remove the fuse that feeds the unit/disconnect it and leave it for a few hours.They can be a little temperamental at times.

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