I've been dealing with an intermittent AC issue for months. Here's my post in this thread https://www.tahoeyukonforum.com/threads/ac-randomly-stops-blowing-cold.150065/page-2 . You may have a similar cause. Look up BCM issues and see if yours is acting similar. You can reset the BCM right at the engine fuse box. There's a connection on the firewall side of the box, I think a 13mm wrench will remove the nut, lift the cable off the stud for 1-2 min, then re-install. See if that fixes it. If so then your BCM may need to be replaced.
