2007 tahoe ltz no power lift or close
Just tonight my auto lift gate stopped working. I had the gate up for a while then I pressed the button to put it down and did nothing. I manually put it down and pressed fob to rais it and nothing except flashing lights, tried handle and makes noise but doesn't lift automatically, can lift manually. Tried button inside on head liner and don't work either. Motor still makes noise and latches unlock but power lift does not engage and get "close rear gate" on my my dash. Can not find Info or video anywhere of the exact problem.

Need a scan of all the codes families, not a low-end scan tool that just reads the P codes but one that reads the U, C and B codes. There are sensors in the lift gate, so you need to see if any codes are being set.

2018 suburban stuck open on Memorial Day; can’t close.
Well, had it for a year and about time I join a forum for support and knowledge.
Memorial Day party requesting my attendance and the lift gate is stuck open. When I try to physically close the left “compression arm” seems to be holding it in place.
onStar trouble shooting little help.
Praying for easy reset type solutions.
Thanks folks for any advisement prior to the wife murdering me. be well

Not sure on a '18 but my '11 there is a lift arm that connects to a motor and 2 struts that hold the gate up. On my '20 Traverse and my '16 Equinox it's a hydraulic opener run by the left ''strut''. I would try disconnecting the battery for a few minutes and see if it resets the module that runs the opener. Dealer will scan the system for codes as there are safety's along with sensors that the tail gate control module uses to actuate it.

Just last week I replaced the two liftgate struts on our 2011 Yukon; our issue was that liftgate would open about a foot, then move down and lock. Switching to manual mode, found the support struts would not hold the liftgate up, so ordered a pair of new struts from Amazon for $27 (O'Reilly was like $50 each).
I used an 81" piece of wood to hold the liftgate up, took off the struts one at a time and replaced them, now it works fine. One of the old struts had zero resistance in it, the other felt OK.
So I wonder if one of your struts could be stuck in the extended position???
