Hello, The switch on my passenger side electric window is getting dodgy and doesnt always click right. So 2 things... 1. can anyone tell me if the switch is the same on all 4 doors? or do I need the particular one... 2. can anyone give me an idea of how to fit it? ( is it door pannel off?) 3. Dont suppose anyone knows where i can get one? - I guess audi will want £50? Cheers Brian PS - my speaker on the drivers side is also dodgy - do I need to take the soor pannel off for that too?
