SL55/63/65/R230 AMG: Keyless Go acting funny and not working
The passenger side is kind of weird. When I place my hand close to the door handle, I hear a quick flapping sound inside the door. It sounds like the actuator is flapping on and off inside the door, but it didn't push the door lock knob up. the knob remains down at its locked position, but I can open the door if I pull the door handle. The door opens when the lock knob still remains at its down position.
The driver side sounds like totally dead. It only locks and unlocks when I push the lock and unlock buttons on my key. But when I place my hand close to the door handle, only response I got is the flapping sound from the passenger door side.
And the start/stop is not working. But when I push the start/stop button the flapping sound comes out from the passenger door as well.
Any advice on where I should start with to diagnose this?
Thanks,
