2000 Century HVAC Problem

[jwichman]

The MAX, VENT, BI-LEVEL, HEAT, BLEND, DEFROST selector switch quit working yesterday. The AC still works when the button is pushed. No matter where the selector switch air is blown out under the dash, the dash vents and at the defrost windsheild locations all at the same time. The MAX AC recirculation damper does not open either. Anyone experience this before? What was the fix? Any other suggestions?

Thanks,

Sounds to me like a vacuum line came off under the dash, more then likely. Your going to have hunt around under there for a vacuum line that is loose or broken.

Good luck,

Yes I have nosed around both under the dash and under the hood. One would think that you would be able to hear a vacuum leak, especially under the dash. No such luck. I will have to do some additional more in depth looking I guess.
