Brand new to forum, but I'm having a similar problem with my 2007 Tahoe LTZ. We've owned the Tahoe for about a year, purchased from the dealership with very low miles. Been operating without incident until two months ago. The rear glass pops open whenever you open the tailgate. I don't think it is a remote issue, because it does it either by remote actuation or manually at the rear latch switch, or at the overhead console switch. As the hatch opens the rear glass pops open after about 1/3 of the way up. Started happening intermittently, and now occurs all the time. any help or suggestions would be greatly appreciated.
Thanks Bill M.
