Every time I think I know what the issue is, it turns out to be something else. I’ve confirmed it’s not the button on the lid, or the lock itself, the lock just not receiving a signal when it should. When I press the hatch button on the key. the lights blink twice on the vehicle but no voltage is applied to the line. There’s 4 pins, I haven’t been able to figure out what does what. I’m not sure if the cable is damaged somewhere, but I’m also not sure how to check. I can’t find any information on where it connects, or the easiest way to access that connection. I’ve checked all the fuses.

Any advice is welcome I’m stuck.
