My C2S coupe has 900 miles on it. Starting a couple of days ago, when I would restart the engine after having driven the car somewhere, the passenger window would lower and raise about 1/2" on its own. Doesn't happen when the car is cold, and I'm not fooling with the window switches or the doors. The battery hasn't been disconnected, so I don't believe it has to do with "storing the end position" of the windows - or does it?

Maybe the wiring harness was damaged in the paint booth fire at the factory or the guys there are just more creative than dangling a bolt from a string inside the door

Anybody else??

 

That is a known problem,--but relatively rare today. It wouldn't hurt to "store the end positions" by continuing to depress the switch about 10-15 seconds after it hits the stop,--in both directions. Try this twice.

Then take it to your dealership.

 

Thanks Edgy, will do.
