Wiring gurus - diagnosing rear trunk latch inop

[seningen]

If you can pull the switch and have a multi meter, you can see which combination of pins shorts when the switch closes and is open otherwise.
If that works, then the switch is good. You can then probe the pins, should have 12v on one of them. If there’s no 12v, I’d check your fuses.
Idk if the switch controls latch directly or if there is a relay in the path.
