Wheres the door pin switch

I'm trying to locate the door pin switch. My belts stop working on the drivers side and the visual indicator of door open on the instrument cluster doesn't show when the door is open. Can anyone help me locate the switch?

I don't think there is one. IIRC The door-open circuit is connected to the lock mechanism.

It's possible it's disconnected behind the door panel. It is the latch that determines if the door is open/closed.

To test you can manually close the latch on the passenger door with your fingers.
