SOURCE: how do I replace a 2000 Toyota Avalon blend door actuator?

The blend door actuator is one of the heating control units found in the center console. Purchase a console tool and remove the plastic console cover after dismantling the front of the heating control. There should be a series of clips that hold the plastics on. Once you get to this point you'll want a tray to keep track of screws. Unscrew the mounts for the control unit and pull them out, taking care not to damage the ribbons or cables connecting the unit to the heating and cooling unit. Unplug the offending actuator from the control unit and plug the new one in. Then reverse process to reinstall the control unit and plastics.

You can find diagrams on google, and the actuator on amazon.com or rockauto.com.

NOTE: Caution; make sure to disconnect the battery to prevent potential electric shock.

Why doesn't my 2001 Ford Taurus have heat but the blower motor works but only blows cold air.


Is the coolant level full ? Are the heater hoses hot to the touch ? Do you know where the heater hoses are ? Out in the engine compartment going through the fire wall into the passenger compartment . 2 hoses , one carries hot coolant into the heater core the other is a return back to the cooling system . If hoses are hot you have a temp. door not working . When warmed up what does temp gauge show ?
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the manual A/C-heater system is determined by the position of the temperature control knob (between COOL and WARM).
  • This control knob is connected to a potentiometer mounted in the integrated control panel. This potentiometer is electrically connected to the A/C electronic blend door actuator that operates the A/C air temperature control door.
  • The A/C electronic blend door actuator contains a reversible electric motor, another potentiometer and a printed circuit board. The wiper of the potentiometer 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 each potentiometer. The voltage available at each wiper indicates the position of the potentiometer. The printed circuit board drives the actuator in whichever direction is necessary to make the actuator wiper voltage agree with the control wiper voltage.
System uses a reheat method to provide conditioned air to passenger compartment.
  • All airflow from the blower motor (18527) passes through the A/C evaporator housing where it can be cooled and dehumidified.
  • Temperature is then regulated by reheating a portion of the cooled dry air and blending it with the remaining cool air to the desired temperature.
  • Temperature blending is varied by the A/C air temperature control door which regulates the amount of cooled air that flows through and around the heater core (18476), where it is mixed and distributed.

My air conditioner is working but won't blow out


Are you saying the temp blend door is not working?
If yes, it's the control head or the temp blend door motor on th plenum case under the dash. Buy used on ebay.

DO you have manaul or electroic controls?

If electronic

A/C Electronic Blend Door Actuator The A/C electronic blend door actuator is located on top of the A/C evaporator core housing (19A553) assembly.
  • Its function is to move the A/C air temperature control door on command from the control assembly.
  • The A/C electronic blend door actuator 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.
  • A five volt signal is applied to the ends of the potentiometer. The voltage available at the wiper indicates the position of the potentiometer. The expressed value of 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 whichever direction is necessary to make the actuator wiper voltage agree with the control module wiper voltage.

04 Chevy Silverado. Dual climate control is blowing cold on driver's side and hot on passenger.


with truck off, move passenger to full hot and driver's to full cold. turn key on and run air for 15 seconds.

turn key off

move climate controls to opposite positions and turn key on again with air on. Run for 15 seconds. turn key off.

center temp controls and turn key on again. this should fix you.

My a/c won't blow cold and heater doesnt get hot


Is the heater working? Turn the A.C. off with the car at an idle. Turn the A.C. on and listen for the compressor to turn on. (should hear a click under the hood and the motor should change pitch. If no noise, the compressor is not comming on. The o-rings were bad about leaking on these cars, letting out all the freeon. If there is no freeon, the low pressure switch won't let the compressor run.

Item Part Number Description 1 — Air inlet door 2 — Temperature blend door 3 — Headliner airflow 4 — Auxiliary mode door 5 — Floor airflow 6 18476 Heater core 7 19860 Evaporator core 8 19805 Blower motor
The auxiliary A/C and heating system has the following features:
  • The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
  • The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
  • Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
  • The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
  • Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
  • Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.
---------------------------------------
I would say the auxiliary mode door (#4) electric motor is not wokring.

=============================================
Auxiliary Blend Door Actuator —Air Distribution Removal and Installation

  1. Remove the screws.
  1. Disconnect the blend door actuator electrical connector.
