I just bought a used 1993 Audi 100 S and it has some mechanical issues.

1) The radio is getting power to it, but not working.
2) There is a constant interval warning chime everytime the car is turned on and when the lights are on it goes from interval to a constant chime.
3) It is affecting the driver side door lock and the automatic door lock on the driver door.

Does anyone know what could be causing this problem?

Please help if possibe. Thanks!
