Mixer vent ... with the engine running (and radio off) change the vent settings ... go to defrost then lower then upper air flow . . switch the temp from hot to cold back ... you should hear the vent opening and closing ... The vents are vacuum actuated ... the only controls they have are a vacuum solenoid and flapper (under the dash) and some have a rotary switch that has both electrical and vacuum inside the switch or ///////// a vacuum line may have come off
