2001 Z3 2.5i, Trying to troubleshoot my windshield wipers. They keep blowing fuses. Motor was working fine then all of sudden it started blowing fuses. Now every time I try and switch them on the 15A fuse blows.

Which fuse is that? Here's some posts about Fuse 44:

... the radio/wipers go dead... radio and the wipers share #44... fuse 44 had blown again...

... to the dealer this morning. They found the short in the switch on the steering wheel column for the wipers!!!

UPDATE: I have been doing some troubleshooting. Fuse 44 blows as soon as I turn the ignition to position one. I have disconnected the ditch in the steering column, still blows. I have disconnected the washer pump, still blows. I have changed the relay, still blows. Only thing left is the wiper motor. I have read that there is a micro switch inside the motor that seems to go bad. Anyone have any experience with this? Is there a wiper control module and if so, where is it located?

Control unit for wiper washer in eBay:

And from ECST:

Located behind glovebox, but is called a relay in the attached instructions. I wonder if either the switch or the module can short the fuses.
