my electric door locks work fine when using the remote control but do not work when using the switches on the doors (none of the switches activate the locks). Since all locks work with the remote and none of the door switches activate the locks I don't suspect wiring. Where to look / how to troubleshoot?

Hello, the (remote control doorlock receiver) signal goes to the doorlock actuator.

The (doorlock control module) signal goes to switch on the door. I don't have the location for that module in front of me. Maybe some of the others have a location?
