Trust me on this, I took my wiper motor apart (gears section) after it stopped doing the full cycles. I discovered the cheap worn plastic gear and almost had a seizure. What did they think??? Putting a plastic gear against a smaller brass like material gear.

I am not a engineer but I could have figured that one out. Here in Canada, we sometimes have 6 inches of snow on the car or the wiper simply sticks to the winshield in ice.

Picture this; the night before, you go party and come back with the wipers on intermittent because it is snowing. You forget the wiper on and the day after, you start the car, the wiper starts going up and before you know it, it strips the plastic gear. Those Canadians you'll say!!! Well, if you had fun at the party it is worth it at least.

Bought one at MB for 250 Cdn + Taxes and replaced the whole thing myself. Keep the sliding part of the arm lubricated at all time!

Question to M.B.Doc. Since the part number had changed, does it mean they now have a better assembly (no plastic but brass maybe).

I still think it is a very good car and I would buy another one without hesitation. It does the job superbly here in all kinds of weather.

Have a good day everybody.
