It's quite obvious from the photos, that the new motor has a diode or resistor and the old one does not. Maybe the larger plug & motor belong to another M/B model other than an ML. Or maybe the motor is not the problem at all.

Wiper motor version changed around 02/99. From previous posts looks like internal gear broke. He bought motor from fleabay had it shipped to Hawaii. And now he's stuck.

And gameboy plyers will still insist that providing accurate information about their sleds is irrelevant.

Well,

Instead of getting off the car, lifting wiper and removing twig from under it, I, activated the system, tryed to lift the arm as it swang by but instead, held it and ... it strip the center of plastic gear.

That's right, stupid is as stupid does.

There are separate gears available for W140, etc.. I haven't seen any myslef for the W163.

However, it looks like Cardone (a major volume rebuilder) offers rebuilt units thru outlets one wbe outfit photo "looks" like it includes gear housing - for $76 + $40 core.. I'd check by phone, photo's can be deceiving sometimes on this shit.. I have seen other photo's (Autozone) that look at $60 + $15 core that look like they might not have a gearbox..worth checking shit out closely on reman's..

You should be able to adapt new motor. Can't help you with internal diagram. More I look at it more I think it's wrong.

Hi Guy's, sorry to revive and old thread. I have the exact same problem as "fporro". Any chance this solution worked out? I'm trying to get another 2 months out of my ml before it goes for scrap.

Explain your problem. "Same as so and so" never works well.

I have to replace the wiper motor on my ml as well. I picked up a unit and foolishly didn't take my original when I went to the wrecking yard to pick it up only to find the connecters are not the same. This is literally the same situation and visually the same units that fporro has dealt with.

When you got it from the wrecking yard, did it have any paint markings on it saying what yr. and model it came from or a tag saying same?

That's the only unit they had.
When I looked it up and called them. It did fall into the "up to 2/99" category.
I call a friend at the mb dealer in parts and he said that there is 3 different versions of the motor and it requires a vin to confirm the right one.
I just called another yard that has a unit and they informed me it's the larger plug unit (the wrong one for my application)
I can certainly take it back, but I'm trying to "patch together" the my suv, like I mentioned for another few months.

I don't suggest that because if you start switching things around you could possibly zap your AAM and then you might as well junk the truck.

Take it back, get your money back and get the right one.
