Just fixed both my headlight wiper motors, for free.
Both wipers had been either not working, or working intermittantly, and not parking properly. New units are an arm and a leg, I overhauled them as follows.
1 Remove wipers (one nut, and wiggle to unloosen the splines)
2 Remove headlights (as per Haynes manual), four torx bolts, incl one that holds the sidelight on.
3 Remove wiper motor assembly, two nuts.
4 Disconnect wiring. The connector has a "pull up" fitting, which must be taken to the end of it's travel, I levered it up with a screwdriver. If you don't take it all of the way until it clicks, you won't get the connector undone.
5 The motor housing cover is a snap fit onto the body, lever it off with a medium sized, flat bladed screwdriver.
6 The gear assembly is heavily greased, and in my case (a 1998 car) the grease had hardened. Remove the two grommets from the wiper shaft (one metal, one rubber) and withdraw the shaft. Remove the gear assembly which is visible, and lift off the top plate, and clean any old grease out, spray liberally with spray oil (WD40 or similar) and re grease.
7 Remove the motor (again, using a medium, flat blade screwdriver)and pull worm gear off the end. Spray the inside of the motor liberally with either switch cleaner, or spray oil, or both, and apply 12v dc to the power terminals. I used a connection from my battery charger, the motor ran hesitantly, and sparked a lot, but after 30 seconds or so seemed to have burned off the impurities from the communtator etc, and ran perfectly.
Reverse the polarity, and run the motor backwards for 30 seconds.
Re-assemble the units, and take you wife, girlfriend or whatever out for a meal with the £120 you have just saved.
Both wipers now work well.
Hope this helps
