Might try checking your fuses. I've got the same problem on my DD 97 Lesabre, drives me INSANE! I did not fix the problem with fuses and have not fixed it yet but it's worth looking. What I did discover after much research, is that sometimes the mode actuator switch can either malfunction or just stop working all together. It's possible the flaps which change air flow may be stuck on something, but that's more unlikely. I don't know where the mode actuator is located on our F bodies, but I know you basically have to tear the dash apart to get to it on my buick. MAYBE that will point you in the right direction. Good luck, and welcome to forums!

Sounds like an issue I had with my Chrysler. Most models you do need to access behind the dash. My issue was the little actuator arm was made of plastic that broke and the vents would get stuck closed. Little DIY I made one from metal. That's all I can think is wrong without knowing to much of the in's and outs of your system first hand.

You have lost vacuum to the HVAC controler, It defaults to defroster when this happens. Either the vacuum line in the engine compartment is cracked or broken or disconnected OR someplace inside the car, the line has become defective.
