Power Lift gate problem.....Help

[Sigman4577]

My interior button wouldn;t open it also, I just put a new latch in and crossed my fingers and pushed the botton on the liftgate and bamm it works. The remote and the interior switch all work to open close the gate. Glad I did it myself and not the dealer. Tool all of 25 minutes.

What were your symptoms prior to fixing it with the latch?

2008 Yukon Denali - Power lift gate will not open or close with FOB or overhead switch. No sound, no lights flash, nothing. Will open with manual button on liftgate handle. The FOB opens the glass hatch. Any ideas?

Mine did this. Then I replaced the glass cause some a hole broke it. After i changed the glass it has worked flawless. I am guessing it has to do with alignment of the glass latch some how.

Well, I guess it’s my turn. Been cold and I thought the gate was inoperable because of the cold. I am not sure if the latch should give any DTC when it fails. All was god yesterday and this morning. I tend to power open and close manually. Anyway, power open and close is now inoperable. With the overhead switch set to allow for power operation I can only manually open the rear gate. Glass works fine with the fob. Any tips for diagnosing the latch? I am heading up north this weekend. What if my gate wont open for me?
