Possible loss of vacuum to dash or blend air door. The blend air door is notorious about breaking on these models. If it is the blend air door you will have 2 choices. Either remove the dash to replace it or use a Heater Treater repair kit. I personaly would use the kit.
Look on You Tube for the video on how to. You can order them online.

I have the same problem,, I have checked the valves,, one was crimped as it had melted,,, still no luck. As I was driving yesterday I would hit bump, and it would switch to the dash, hit another bump back to the vents, then no cool air,, now its stuck in the dash

'When function door is in defrost position, air inlet door vacuum control motor is at no vacuum, admitting only outside air into passenger compartment. Panel/floor door and panel/defrost vacuum control motors are at no vacuum, directing air airflow to defrost duct and side window demisters. Temperature can be adjusted to heat or cool air below outside temperature. A/C compressor will operate if outside temperature is above approximately 43*F (6*C). Blower motors is On.'
You're either not getting a vacuum source to the Panel/Defrost Vacuum Actuator or the actuator's diaphragm has a hole in it.
