My problem was the passenger side window motor's module was blown; it didn't show up on the dealership tool. In fact, they told me they could not see a problem ... and couldn't figure out why it wouldn't work ... I order window motors from Auto Zone (Dorman brand) and the other major parts sellers(no name brand). So, I went to the junk yard after finding in the VW website that I could use a hatchback PW motor or convertible ..... started with hatch -back which worked and later the same months a 2005 PW motor from a convertible showed up in a yard 45 min from my house ... everything works perfect ... including the window dropping a 1/2 inch before opening. My Tip ... make sure all you windows work and use OEM parts (they are at the salvage yard & used part sellers).Hello, I have a 2005 convertible and last time I put the top down it would not go back up. Did the manual release to get it back up. Any ideas to begin troubleshooting on my own?
