Buddyinstl is is right. the same thing happened on mine. the heat controls would not work either i tried to turn the heat down but the air would not get any cooler until i put this tube back on.
Easy fix. The vacuum hose has come loose. Happens all the time. The hose is about 1/2" in diameter and can be found under the hood, in the middle of the engine compartment, on the drivers side. Just take a tie wrap and tighten it down over the plastic inlet.
