I'm wondering what year car you have. If it's the falcon I'm familiar with, they were all controlled with cables and swing doors if I remember right. You might have a busted tab or your cable came off the tab that swings the doors opens and shut under your dash. It's a tedious job to do but if you get under and find how your vents are connected, you will be able to tell which side is not working. They usually split in the middle on some of those old cars and that's where I would start. It's connected to your exhaust as that's how you get your heat. Find an old chitons at the library and see if there is a diagram for your model car to see how it's all laid out under there so you don't have the whole dash torn apart and waste your time needlessly. That manual might also answer your question as well. Reading is a valuable fundamental.

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."

Driver's side defroster and heater vents blow cold air but the passenger side blows hot. Both sides should blow hot The temp is set any temp and it still does the same thing. It is winter so I don't know...


The doors that open and close in the heater control unit are ran by motors. It sounds like a motor has quit in yours. When turning on the defrosters the motor closes the door to the heat for the floor

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.

Passenger side blows hot air when front control set to Air


you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.
