C Class 2003. When I lock the car, the passenger side door lock bounces up and down like a machine gun - three or four times! It also does it when the auto lock function activates when driving away. Sometimes it stays in the locked position sometimes not. Anyone have any ideas??
Regards

You need a new lock actuator, very common issue. This has nothing to do with a relay. You need to take off the door paneling to install a new lock actuator
