SOURCE: 1998 Mustang - AC blows only through Defrost vents
You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.
SOURCE: 2001durango vent only blows air through face vent and defroster.
the vent door is broke in the heater control box under dash
SOURCE: Vent control
You have a vacuum leak.Defrost is the default postion(no vacuum).
See if you can locate the small black vacuum line that goes inside the vehicle on the passenger side near the heater core. The trace it back,should see it going to a canister then to the intake manifold.Make sure it is not disconnected or broken somewhere.
SOURCE: climate control system only blow air out defrost vent
there is a good chance that you blend air door is stuck closed over your heater core and therefore not allowing the heat to flow, also your door that opens and close your direction of flow from the floor ,das,vent and defrost.your going to have to remove the lower cowling of the dash on the passenger side analso some of the center dash to actually check to see if the cable,servo motors. are acuating the doors.the issue could be just a stuck door or a misaligned cable or that it came off. that falls under the mechanical side of probabilities. electrical would most likely be a faulty selector switch or a servo motor
SOURCE: driver's side air blowing warm, won't change
Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.
NO HEAT ON FLOOR VENTS
