Or at least perhaps someone suggested on a thread I started to resolve my A/C not working right.

It would appear that the door switch has failed I am speculating. But your horror could get worse as apparently the A/C May start to fail in normal operation due to this as it could somehow affect the calibration of the a/c system. I have only deduced this as I saw some threads on a "reset" proceedure for tahoe a/c problems blowing hot, or not cold on some or all vents. So watch out for a/c issues. My A/C stopped blowing cold on the front vents about 4 weeks after I noted the radio staying on... I am going to address with the dealer and try to document failure of past door related repair to get the door claim reopened (which I suspect started all this)...

Ironically, and I have not had time, but I dont think the switch is readily visible. Of course I have only looked at night LOL so perhaps its right there. Its amazing how little projects become impossible with no time these days...
