Sounds like it could be the climate control module. You would find that under the dash. You're going to need the book.
A Caddy I had used a test of turning the controls to the coldest position with the unit on and then starting the car. Shutting it off and putting the temp up to highest. It was so long ago but I remember it was called "Failure at 85degrees" or something like that.
Sorry, couldn't help more but it was a while ago.

1. check fuses
2. check vacuum hoses
3. possibly a defective electrical climate control head (A/C heater control panel on the dash)
