Power Lift gate not working 2010 Yukon (no noise)

[TechiMan]

So yesterday at Costco I pressed the button to close my gate and it did nothing... so I pressed the button on my remote and it closed just fine, then when I got home I tried to open the gate with the button on the handle and I got nothing.. so I pressed the button on the remote again and the lights flash but I get no sounds at all in the gate.... so I thought it might be the override switch... so I tried to use that to open the door and still nothing... so I was able to pull some stuff out trough the glass but the main gate seems to be stuck closed and fully loaded so now what do I do? I checked the Fuse (44) and it was good and the glass button works so there is some power back there. I am hoping I will be able to get my stuff out trough the side doors but if not how do I override the latch to get the gate open?

thanks in advance.
