SOURCE: cold air on passenger side warm air on drivers side

Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.c976077.jpg

SOURCE: 2000 Buick LeSabre No heat, blows cold air.

check to see if both hoses are hot going to your heater core if they are then core is fine.That would point to your temperature sensor.

SOURCE: heater not working in my

This sounds like the blend door actuator. This is a little door in the vent box down under the passenger side dash that opens and closes to change the vent temperature from heat to a/c. It is a little motor that opens the door. It tends to stop working due to the elements that it is in. I hope this helps!!! Thanks!!!

The heater kicks on but only blows cold air


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Driver side blowing hot air passenger side blowing cold air


I'm having the same problem except on mine it's the driver's side that's blowing cold. Do you have the pictures in a finer resolution? I can't make them out and when I zoom, they are too grainy. Does the replacement require removing the dashboard? What's the general cost of the acuators? Are they readily available at like NAPA or other parts stores?

My 2004 Avalanche ' heating system will not heat. No matter what the setting it either blows no air or cold air and it is 25 degrees outside so this is a problem. The engine is up to temp and I have tried...


The most likely cause is a failed blend door actuator; however I recommend a little troubleshooting. First, can you hear a clicking sound behind the dash when you turn the setting to hot? If yes, it is certainly the actuator stripping its gears. If not, check to make sure the heater hoses are both hot as they connect to the heater core at the firewall (in the engine compartment). If one or both of the hoses do not get hot, there is a blockage caused either by an air bubble or a stuck water control valve in the heater hose. If the hoses are both hot, the indication is again the blend door actuator.

Below are instructions for replacing the actuator. Look at the diagrams carefully--the big arrows point to the front of the truck and the actuator is on the side of the heater box above the outlet duct that runs to the driver's side of the floor. Also, the actuator is expensive, so I recommend you make sure it's bad and shop around a bit to get a good price. To check out the actuator, first see if you can turn the blend door by hand. If you can't turn it, maybe it's jammed. Also, reconnect the actuator after removing it and see what it does when you turn the heater to hot.

Removal & Installation
  1. Remove the floor air outlet duct extension (1) from the floor duct (2).

    1. Line up the heater/defroster valve lever with the blend door actuator cam slot.
    2. Line up the A/C valve lever with the blend door actuator cam

  2. Install the blend door actuator mounting screw to the HVAC module.
    1. Tighten the blend door actuator mounting screw to 14 inch lbs. (1.6 Nm).

  3. Connect the electrical connection at the blend door actuator (10).
  4. Install the floor air outlet duct extension (1) to the floor air duct (2).

2003 mercury grand marquis LS heater does notr blow hot air, blower blows but cold air comes what is the problem


The blend door is stuck in cold position. That usually happens because the blend door actuator has failed.

You will need to test and replace the blend door actuator.

To replace the actuator you will need to take apart the dash and remove completely the instrument panel,d isconnect the connector, remove the four screws, remove the temperature blend door actuator and replace it.

The replacement is not a job for beginners, since you have to take apart the dash to access the actuator.

Regards.
