Automatic Window Lowering

[jcskis]

I just found this forum and joined in the hopes that someone could answer a question on the automatic window lowering feature. As of yesterday, when I open my driver side door, the window still lowers to clear the roof, but it then immediately goes back up, preventing me from closing the door. I have to lower the window by using the switch, close the door, and then go to the passenger side to raise the driver window using the switch again.

Also, while driving today, I noticed that when I hit a bump, the window would lower slightly as if I was going to open the door. It even turned on the interior lights like I opened the door.

Is there a malfunctioning switch that could be causing this and is it difficult to replace? I would prefer to do it myself rather than pay Porsche a small fortune to do what is probably a relatively simple fix.

Thanks,
John
