Further to all the good and useful threads that have gone before . . . and having just succeeded in changing my 01 Cooper wiper motor, I took the chance to record the operation in photos.
Let's be honest . . . . it is a
bugger of a job . . if you don't know how, but BMW are taking the mick if they get the sort of prices quoted on this forum for this job. Once done, it should be very easy to redo it in around 1 1/2 hours and I'm sure the word is out in the dealerships how to do it easily. The simple trick is, (as Randall quite rightly states above) bite the bulet and remove the tophalf of the plastic bulkhead. It's very easy to do and then you have no access problems. The only real problem is undoing and reconnecting the wiring block. Anyway, the attached documents have the photos in them. good luck.
