I did not replace the wiper motor.
The relay contacts were worn down/crudded up and dirty.
Cleaned them, replaced relay and good to go until new relay from tischer bmw shows up with new "closing panels".
My E-box cover is fastened with zip ties as the captive nuts (in the bottom half) stripped out of the plastic housing when I went in there back in 2007 for another repair. Cover is snug, no moisture getting in. I have a knife that cuts the ties easily.
*Make SURE that you reinstall the pollen air filter housing bottom half correctly so that water runs where it is supposed to off of the windshield and out the side/inner fender drain .... not down into the E-box well. We have had enough threads about this "problem" recently including the ones where I posted marked up photos of water flow (people having frozen brake boosters b/c of water in driver side well).
For emergency repair:
1. metric hex/allen keys
2. small pick/screw driver to get cover off relay
3. little bit of sand paper/emory cloth
... should be good to go.
