Hey, mine trashed itself too... I removed it and rebuilt the whole thing as a straight drive, so now don't have positional cutoff cams and have to watch how far it goes. Crappy design. But it still works...I will have to get the replacement ass'ly either new (heard there are several) or from a boneyard, sooner or later...metal gears would be nice. The factory moonroof itself is great, well built and never leaked...but the motor assl'y is junk. So far, the only original part to fail after 44k miles.
