I have a 1977 530i that was parked for 15 years and I just purchased it. The horn does not work and I have done the following to repair it: pulled the steering wheel and cleaned the horn ring and all four (4) horn buttons. pulled the horn itself and it works fine. checked the relay and it is fine. looked at the horn wiring and it looks ok. where else should I look and what more can I do to solve this horn problem? Thanks, Jim Petersen
