Inner tailgate not working

[Cootr68]

22 denali 2500hd my inner tailgate stopped working. Happened even before I got the recall done. I've tried the push and hold method to lock/unlock it but get no response or tail light response yes the fob is in my pocket. Dealer is no help. I can hear the button click but it does nothing. Bought truck new and it only has 27k miles. Yes I have tonneau cover I've tried with it open I've tried slamming it pushed and pulled. It just won't do anything. I thought the recall may fix it but it didn't. Bout to put the fire wrench to it. Also I haven't got any warnings saying it's open while driving. It's just dead.

Try holding key fob right next to buttons, and then push and hold to activate/deactivate the inner tailgate.  Also, make sure fob batteries are good.

Nope got nothing just button clicks. I think I'm just going to have to make a dealer appointment and have them give me something to drive and say call me when it's fixed.

I can relate. It’s incredibly frustrating. I had a 2022 2500 in which the dealer replaced at least a half dozen switches. I had more inner switches fail than outer switches. I siliconed the drain holes in the top grab handle but still had a couple of switches fail after that. In the two years that I owned the truck the tailgate was broken longer than it was working properly. I got rid of the truck and bought a 24 Denali. I’ve only had it a month but the first thing that I did was to fill the entire top grab handle indentation with black silicone caulk. Plugging the holes keeps the water out but then the indentation fills with water/ice so I caulked it flush to eliminate that. So far so good. Hopefully, GM has a better batch of switches now.
