Sounds like a repeat of all the problems I'm having..sounds like a 420SEL thing only differnecr mine is a 1987 model. Loo9k forward to somebody coming up with the answer...Almost forgot my Seatbelt light is stuck on instead of going out after 6-7 times of blicking. Anybody have an answer for that one? There is no wires to the seatbelt assembly and this sticking just started. Thanks!
