My A/C, Heater, Defroster switch is stuck on Max A/C and no matter where I turn it it stays on Max A/C and pumps the A/c out the windshield defroster vents. Is this an indication that the selector switch is bad and should be replaced or is it a different problem. Please help - It's getting hot in Texas and it's just fogging my windshield up.......

This is just a guess, but it may be vacuum lines under the dash that have gotten disconnected
