Thanks for the reply Tom. Its the courtesy lights that are flickering - I should have made it clearer. I hadn't thought about the ground issue but that's a possibility too. I haven't had anything apart to pinch anything - the only thing I've done recently is added one of Marc's performance chips and the door thing was acting up before then.

I'll see if I can check the grounds, the door switches are available so I'll order some just in case.
