SOURCE: 2000 Buick LeSabre A/C blows

Depending on the model, normally there is a door at the center of the air duct for the AC. It should be found underneath the dashboard at the center. Normally when the motor of the door is faulty you would not get the correct mix or will not get a constant air temp blowing on the two sides. Have the motor checked out. The other scenario is the thermostat or the temp sensor found near the same location towards the evaporator or the part where you can see the coils if you remove all the cover. Inspect the wiring to that part make sure that there is no exposed wire or loose wire. Either there is an issue with the wiring or the thermostat has gone bad. A bad thermostat would mean no signal to the AC which activates the door to send the correct air temp.

Defroster not blowing


your blend door motor IS your defroster problem , as it is needed to direct heat mixed with the ac to properly defrost the windshield . if when you change your blend door motor and the problem still exsist , then youy have a defective blend door package , meaning one of the doors are faulty , which could get very expensive to repair , good luck !!!

Peugot 407 heater not working


You more than likely have a problem with the temperature control blend door inside the air ducting, this door sits between the heater core and the AC evaporator core and mixes the air for the desired temp at the registers/vents. More than likely it is sticking due to being warped from heat. To replace this door and its actuator requires the dash be removed from the car.

My 2002 Avalanche 1500 4WD is not blowing hot air from the heater. The heater hoses are hot but I am only getting cool air. What should I check to see what the problem is?


Gas. Haven't dropped any pencils down the defroster vents have you? Sounds like a mixing door in the heat/ac box is not moving. Could be the motor to the door or a lack of vacumn to the controls. Make sure your canister under the hood is hooked up(probably is since you did not mention having defrost air only). If it has a cable instead of vacumn control for temp, verify it is connected and operating properly. TJ

Ac blows out cold on dravers side hot on passenger side


If the vehicle has dual zone climate control, either the air mix door is broken or the motor that controls it is broken. It may also have the vacuum control system, which could mean a loose vac line or a broken diaphram. If its not a dual zone, then the air should be the same temp both sides as the mix door is one piece. It sounds like a mode door controller is bad, either case.

A/c temp on max 27 a/c temp on norm 50?


Was browsing the ford f-150 forum and found that Ford has a lot of issues with it's AC, some too hot and some like yours, way to cold. At MAX it should read around 42. Best 2 solutions I've found are:
  • Blend door/Blend door motor
  • Dirty EVAP coil
Here's a pic of what the Blend door/Motor look like and instructions on how to replace it. Wish you the best of luck.

Removal & Installation
  1. Release the stops and lower the glove compartment door.
  2. Disconnect the connector.
  3. Remove the two screws. Rotate the blend door actuator and bracket assembly. Remove the electronic blend door actuator and bracket assembly.
  4. To install, reverse the removal procedure.

I have 1998 cadillac STS and the heater blows cold air only


this problem is caused by a defective air temp control blend door motor, this door and actuator motor is located inside the dash between the heater core and the AC evaporator core, it shifts airflow through the heater core or the AC core or mixes or blends the two for the desired temp at the outlets, the motor will have to be replaced. This is a very common issue.

the door opening & closing on Max a/c is the inside/outside air intake door.
The temp blend door is the one you are concernd about. It says you have to remove instrument panel for access. ouch!!!

-------------------------------------
A/C Electronic Door Actuator Motor
The A/C electronic door actuator motor (19E616) is located on top of the A/C evaporator core housing assembly.
  • Its function is to move the A/C air temperature control door on command from the control assembly.
  • The A/C electronic door actuator motor contains a reversible electric motor and a potentiometer. The potentiometer wiper is connected to the actuator output shaft and moves with the output shaft to indicate the position of the A/C air temperature control door.
  • Battery voltage is applied to the ends of the potentiometer. The voltage available at the wiper indicates the position of the potentiometer. The actuator wiper voltage is sent to the control module and matched with the wiper voltage of the module potentiometer. The printed circuit board then drives the actuator motor in the direction necessary to make the actuator wiper voltage agree with the control module wiper voltage.

A/c is working but does not come out the vents cold. have been told it is my "blend door actuator". If so, where is it located, what is the part number, do you sell it, is there something that...


The bleed door actuator is located behind the dash in the AC/Heating ducts above or near the heater core box, it mixes heated and cooled air to give the desired outlet temp. You will have to remove the dash to replace the acuator. This is a dealer only part.
