Interior problem
2004 GMC Yukon 6 cyl Four Wheel Drive 48321 miles

The rear glass window of my liftgate will not close. My 3 yr old son played with the latch, and now the black piece of the lock has flipped up and will not roatate back down to allow the window to close. I have tried the power locks, and I hear the lock working on the door part of the liftgate, but not on the window. Is there a way to manually release the lock.

I read the string on /forum/2006-gmc-yukon-rear-door-lock-vt142798.html but haven't been able to get the lock to release.

Thanks.
