Looking over the wiring diagram, it looks like power for the window motor is supplied through fuse D1. From there it goes to the door harness(s) to an electronic module in the window motor.

The power for control through the window switches is on the middle connector of the three. It looks like that voltage is sourced through the relay for the convertible top. I have power on that middle connector with the key on or off.

I thought it might be the relay. Do you know if there's a way to check the relay? Thanks

This may be helpful or at least lead to more questions. Are you familiar with the location of the relay and how to read the Porsche wiring diagrams?

Here's a schematic for the top relay of a 2000 model. You can click on it if you want to see it larger or download it..


Here's a picture from a tech article about an upgraded top relay that shows a good picture of the relay location (red arrow).
