Welcome aboard.
The heater/AC control has a vacuum switch on it. It could have become unconnected, or a vacuum line broken/cracked. The valves themselves have been known to leak, too.

I had the same problem. Those vacuum connections back there are your culprit. Rub a little vasaline on them....just a little, and make sure they are seated good and that should take care of it.
