How can I open the liftgate once it stops working?

Liftgate Intermittently not working? UPDATE

Sometimes the liftgate on my 2010 Yukon XL stops working. I've done all the standard things to fix it (several latches, module, recalibration, shake testing the wiring ) but my dealership is throwing in the towel on my problem.

Once it is opened it starts working again.

Does anyone know how to open the liftgate once it is closed and won't open? I don't want to spend anymore money on this problem.

UPDATE: After struggling with this problem for 2 years, I finally found the problem. I got so ticked off that I stripped the interior from the rear of the Yukon to try and trace the wiring to see if there was a nicked or broken wire. My initial inspection didn't reveal any problems so I tried again after a few day. I had my wife in the back of the Yukon moving the wiring while I played with the liftgate. She touched a wire that caused the module to start clicking. Sure enough there was a broken wire in the plug to the module. I had the plug replaced and all is now good with my Yukon.

I think disable it with the overhead panel switch?

If you have a shut off button in your console you have to try this.
Okay so something similar happened to me but not the same. Might be your issue as well. Got my truck certified used and I had several items that would work and then stop all related to the overhead console. When I looked up the warrantee repairs on the truck the overhead was changed three times. Here is what I found

The overhead console wire harness is made up of very fine wires and runs across the passenger side to the console. Mine was actually being pinched by the passenger visor bracket holder. Once I freed it up Everything worked. Upon further inspection I noticed a green wire being pinched and shorting out.

Problem solved.

You have to pull down the console and the passenger visor then pop down the liner a lil and you will see the harness.

I am done with this truck I am going to unload it the first chance I get. I can't get any answers to why the liftgate intermitently stops working. I have spent $1500 on fixes and it still stops working. So cya Yukon people I'm going to trade it for a Camero.

Did you check the harness to the switch. Since I replied on also had a friend with a sierra with his harness pinched as well and the sunroof would get stuck.

I haven't checked that yet but what I wanted to try was pull off the panel on the liftgate and try to see what part of the opening sequence is causing the problem. It will partially unlatch then stop. Then it will not open any further and has to be pushed closed. Wait for a day or two then it will start working again. It is totally random, happening every other week or so.

Ok is this plastic strap supposed to be there on the latch or is this something someone added to release the latch manually. It's to the right of the latch.
