As previously requested - because of my ignorance I striped the nut that is behind the plastic nut on the side of the sunroof motor assembly. I put a 17 mm socket on it and turned it in order to manually open and close my sunroof and after a few cycles it striped. This nut has a fine thread and I can't find a replacement anywhere. Visited hardware stores, plumbing stores, a machine shop and also contacted a MB dealer. -------------------------Can anybody sell me a replacement nut???

You might try taking the nut (and shaft it screws on-to,) to a speciality machine shop. They can easily make one from carbon steel and harden it so it won't strip. Try a 'google'search for speciality machine shops. It won't be cheap--figure at least a couple of hours of machinist time

Isn't there a junkyard, excuse me - a "fine automobile parts recycling establishment", near you?

why don't you post the size and thread of the nut, e.g., M8 1.75? Someone could have one lying around.
