Sounds to me like you have a window motor not a wiper motor.Window motors have gears on them wiper motors don't have any that you can see.
I didn't know how those looked like so I googled it. Well the principle looks the same as the wiper motor. It has a worm gear reduction. The gears aren't similar either, mine has a lot more teeth, I think is made to be connected to some component with inner teeth (like putting a drive shaft on it or so).
I started considering the possibility that it might like some vital components. But a wiper motor has a worm gear that slows it down a lot. This output gear already only turns like 100 rpm (i.e. a few revolutions per second unloaded) which could be suitable for a wiper motor.
To put an end to figuring this out I will ask my mom if she can try to take a few photos of this and send it over (I live far away) to me so I can display it to you guys. But I will make my online purchase tonight (CET timezone) because that webshop has come up with the idea to import the "black friday" phenomena here, so they have a general discount for all purchases.
