Looking for some advice.. hear random thumping noises from trunk and at rear of sunroof. (sounds like the sunroof motor engaging randomly) If I succeed at opening the roof, it will magically close; sometimes completely, sometimes partly.

does not happen every time the car is "on" but does appear to be more frequent.

and yesterday, out of nowhere, passenger-side front window decided to lower (without pressing the window button). would not return closed. In fact, pressing the "up" motion of the button was engaging the window and lowering in further. Turned key to ACC on/off serval times while pressing the "up" position and the window finally raised.

Sunroof and window issue.. Connected? any advice on either problem would be appreciated.

Thanks!...Polter-benz

It is connected at the convenience control module under the LR seat cushion. Moisture perhaps? Leaking rear window?
