Hello Mark, The connecting rod between the control knob and the valve may have come off. If the heat knob moves reallllly easily with no resistance that is what is probably wrong. Common problem, easy to fix: 1. Remove driver side speaker 2. Locate the the transfer rod, it usually has an orange or white universal joint on the end of it. 3. Just reach in and slip it back on the heater valve or knob. 4. Close up the dash. If you have large hands or an after-market stereo, you may have to remove the stereo from the dash in order to get to the switch side of the transfer rod.
