Hey guys, I guess it's been a couple months (late spring) that I posted I had lost my cabin heat in my '99 "Burb". Many of you responded with possibilities being, blend door, cooling issues, heater box heat actuator etc. Thanks to all who responded.
It's fixed! It turned out, replacing the HVAC control panel/module was the fix. I got "wind" of this in a YT vid, actually, seeking to get access to the heater box. I was not looking forward to doing this. I replaced this 9pic) with an AC Delco unit from Parts Geek.
This was one of the easiest fixes to-date. Remove the Instrument panel surround (simply pull on it) exposes this panel , a few "unplugs" and reverse job completed.
