Rear wagon tailgate window regulator

So I am playing with my wagon and the rear window does not roll up or down. The motor is moving because I can hear it but none of the gears are working or the motor is broken in the head. 

I took the motor out and from what I can see, there is 3 plastic or nylon pieces ground up in with the grease. So can I get a rebuild kit for this? 

It was easy to get out. Took a few min and that was all. 

That power window motor can easily be rebuilt. The issue you are having is because of worn out torque pins. They were made of plastic or nylon and they do eventually wear out. Very easy to replace and you have the motor a part already. Check out "Tony's Car Care" on Youtube and he shows you exactly how to do it. I found it very helpful when I replaced the pins on a friend's '77 Grand Marquis for the same problem you are having. Cost less than $30 and a couple of hours to do the job. Works great.

I saw that. My motor works fine so I tried to find a gear rebuild for that. I can only find a 9 tooth gear. My thought is buy the 9 steel tooth kit and reuse my 7 tooth steel. I hope that works at a fraction of the cost.
