Drivers side right? I've heard this alot on here. From looking at other threads people say there's possibly a break in the wiring that goes from the door into the car due to to the drivers door being used the most. I've never got in the mood to try and fix mine, sounds like a nightmare lol. I've put up with it for about 2 years now
Sounds logical, but all the door loom goes through one grommet between door and car, and the rest of the door electrics work just fine so isn't screaming at me as the most likely cause. Could the removal of the Bassworks amp have anything to do with it? (Although I can't imagine why it would).
