Defroster got stuck on defrost

Okay, so basically I was driving with my defroster on and it got stuck on defrost. However around a month later I turned the car on and the AC was on. (I had turned the knob over to AC weeks before It actually turned on as mentioned above). Possible actuator issue?

Some makes and models, hvac vacuum actuators, lose vacuum, the hvac system will default to defrost. I'd check the vacuum and actuators. The vent doors are actuated by vacuum. Check for a vacuum leak to the system. Check both under the dash and the supply hose from the engine.
