Sliding rear window

Is there any type of maintenance to do for the power rear window?. I try to keep the tracks dirt free and use silicone spray on the rubber. Is there anything else that can be done?

 

Nope; just remember to close it before rainstorms and you're good to go. Granted mine lives in a garage and not out with tree crap falling, but I don't get anything in there worth cleaning up. Maybe blow it out with compressed air once in a while. Here's what the mechanism looks like.

 

Great. Thanks for the fast reply and picture. Unfortunately, I do not have a garage. I'll just keep doing what I'm doing. I believe I'm one of the few that use it all the time.
