so got my replacement gears and ready to go to town

seems like the motor turns forward but doesn't retract. as i depress the button for "up" i saw one gear turn, and then now I still hear the motor but don't see the gear turn anymore.

pushing down does nothing.

What car and year do you have? It matters.

thanks

924S - seems to be the same mechanism as later 944s according to clarkes

Van

Typically, the teeth shear off of the gears - thus the gears will stop turning.

Have you checked the procedures in http://www.clarks-garage.com/ ? Definitely read through that and follow all of the steps. If you end up having to replace the plastic gears one recommendation i have is to not remove the trim seal around the rear hatch (forward portion behind the sunroof gears). I found (the 2nd time i went in) is that you can access everything quite easily by just removing the trim around the rear portion of the sunroof to get to the gear assembly. Good luck.
