Passenger door won't unlock with key
Since about two weeks, my passenger door does not unlock by key press anymore. The other doors unlock normally.
When I open the door from the inside and press the close button on my key, the door closes fine, the pin goes down.
I already removed the door lock actuator and realized that the motor only starts to run when pressing the close-key. When pressing the open key, there is no sound, nothing, and the motor just does not run.
I also tried a replacement door lock actuator and connected it to the door control module, and it has exactly the same behaviour. I also tried pressing down the door-contact-switch, didn't change anything.
So obviously, it seems like the door control unit isn't giving tension to the motor of the door lock actuator when trying to open.
I would try to replace the door control unit next, is that likely to fix my issue? Did anyone have a comparable issue?
