That dash release button grounds an input to the BCM on the black wire. You can test by grounding that wire. The BCM then grounds the coil on the Liftglass relay in the UHFB which then sends power to the liftglass release motor. The rear switch to open the rear glass does not use the BCM or the relay.
Does the glass hatch open using the switch at the back on the tailgate? In other words does the release motor and switch, power, fuse and wiring work?
If you have a remote control that works does it have a hatch release button and does it work? If so then the BCM and the relay work.
Another test you can do if grounding the dash button does not work is swap relays in the UHFB.
