Hello everyone,
I just purchased this vehicle and none of the buttons work to operate the rear trunk. they are not making any noises at all in the back. From what I can tell there is a button in the driver side door panel and also at the trunk itself but they do not work. I checked the fuses and they all look good. what other components should I be checking to get these buttons to work? is there a relay or something I am missing?
Thanks in advance for your time!

Remove the trunk liner on the lid and check the actuator 2 tork screws unplug it and it’s easy to bench test.

no i sure haven't....unfortunately i have been chasing down a no crank issue, which turned out to be the starter relay, and a coolant leak, which is a stripped bolt that is supposed to be holding the rear coolant flange on. ill try to get back to the door switch soon.
