I’ve been investigating electrical issues of my own. I’m having issues with cruise control not working, and my power windows and locks in the passenger and rear doors.
BCM ground is located on underneath the drivers door towards the engine compartment. Also, if you look at some YouTube videos there is a small ground wire behind the motor that can cause all sorts of electrical issues. If you need any more info, I’d be happy to get that to you.

Thanks

Sounds like you have a loose wire. Did you make any changes to your Tahoe before this started happening, or did it just start happening?

Reseated all grounds , no blinking cluster , but I opened the glove box then it started, so what wires are back there ? Oh noticed cut wires to
