Hello: yesterday I pushed the button on the tailgate to close it. It went to what I would describe as the "first" latched position and stopped. It isn't completely closed but is latched and won't open or finish closing. When I press the button, I hear a noise from inside the tailgate, but is it the sound of the motor trying to pull the tailgate closed, or the click of the latch releasing? Double clicking the tailgate open icon on the remote gives the effect of it trying to work. The owner's manual says: the electric tailgate can be opened if the battery is dead: "contact the dealer". The battery isn't dead. Since it has power, I'm curious if anyone else has experienced this problem. This is my 14th GM truck but first with the electric tailgate. As a retired automotive tech, I'd like to fix it myself if possible. I have looked down from the top of the tailgate edges to see if anything is jammed in latches, they are both clean. I took the access cover off the inside; I can see the white shaft of what looks to be the motors for the latches turning. I attached a cable tie to each white shaft and pulled the shafts to see if that would release them. No success. Does anyone have any ideas?
Thanks,
