When I opened the front passenger door the interior lights would not come on.
I didn't want to replace the whole latch so I took it apart.
I used a Dremel tool to remove the epoxy goo.
Inside there are 2 micro switches connected to a small PC board.
Both switches are Normally Closed.
Black wire is common.
Blue wire connects to the upper switch.
Red wire connects to the lower switch.
As looking at the back side away from the switch pins.
The Black wire and the Blue wire both solder to the PC board right up against the case on the side that the wires enter the box.
The Red wire extends across the block to the far side and against the case side in the middle.
The wires break at the solder connection.
