SOURCE: how to replace blend door actuator in a ford

I recently did mine, I hear you can do it without taking the entire dash apart but I had no luck with it myself. I have to get ready for work but, on mine it was located down and to the left of the radio. its a white box...are you hearing a clicking noise or something? I had to roll the entire dash back and it was still a major pain getting it out.

SOURCE: Blend door for front temp control is stuck in the

Control System Inputs
Climate Control Assembly
The climate control assembly has three control systems:

  • The A/C heater function selector switch combines a vacuum selector valve for direct control of the vacuum control motors and electrical input to the instrument cluster module.
  • The temperature selection is accomplished with a potentiometer connected to the electric blend door actuator that controls positioning of the temperature blend door. Movement of the control knob (18519) from COOL (blue) to WARM (red) causes a corresponding movement on the air temperature control door and determines the temperature that the system will maintain.
  • The blower motor switch controls the blower motor speed through a series of resistors and a relay.
Control System Outputs
Blower Motor Switch Resistor
The heater blower motor switch resistor has the following features:
  • The assembly is located on the passenger side of the plenum assembly behind the glove compartment (06010).
  • Three resistance elements are mounted on the resistor board to provide four A/C blower motor speeds.
  • Depending on the heater blower motor switch position, series resistance is added or bypassed in the A/C blower motor circuit to decrease or increase A/C blower motor speed.
  • An overheating protective device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F), interrupting the blower motor operation in all speeds except HI.
  • The thermal limiter cannot be reset.

A/C Electric Blend Door Actuator
The A/C electric blend door actuator is located on the plenum assembly.
  • Its function is to move the air temperature blend door on command from the control assembly.
  • The A/C electric 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 air temperature blend door.

that clicking noise you hear is likely a relay in the fuse panel that needs to be replaced. the easiest way to find out which relay it is would be to put you finger on each relay as you actuate the device not working. once you locate the clicking relay replace it . to reset the computer just unhook the battery for about ten minutes. if you have an anti theft radio make sure you know the code for it and how to enter it before you unhook the battery.

WHAT IS BLEND DOOR


A blend door is a plastic door inside the air ducting that moves between the heater core and the AC core to provide the desired ait temp at the outlet, either hot, cod or a "blend" of the two air streams passing over the heater core and AC core..

When i turn the heat on it makes a clicking sound, and it blows out cold air, but when i turn cold temp on the clicking sound stops, until heat temp is turned back on. please tell me how to fix this...


Your ac blend door is broken or the actuator that opens and closes the door is broken. The ac blend door moves up and down to direct air flow through the heater core(for heating) or evaporator core(for cooling).

When the door mechanism breaks, the blend door falls down and you will only have ac but no heating.

You can buy a ac blend door kit for your explorer, they cost about $120 on ebay or other places.
search for Explorer ac blend door kit.

The duct is under the the dash on the drivers side. And you will have to cut open the duct to install the replacement door.

Heres a link to a tutorial of how to do the job.

1998 Jimmy with electrical controls for temperature. Replaced Themostat, Flushed heater core, replaced damaged vacuum lines. Vehicle produces heat to heater core but only luke warm interior temp. Rotated...


Suggestion: see if the blend door opens or closes completely to allow all air through the heater core. To see the blend door moving, remove the panel that says "Cut here for service" under the hood along the firewall. I have a 99 Bravada where the blend door keeps moving back and forth constantly. Changed the blend door actuator but still keeps moving. The air inside is only warm since the door keeps allowing bypassed air through.

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.

The HVAC does not switch from cold to hot. Seems like the temp control door is not moving. Air conditioning is working fine. the inlet and outlet hoses at the firewall are both hot.


The location of the blend motor on my 2005 malibu is on the driver side, near the center consol, not easy to get to. Before you try to remove the blend motor, unplug the wires it, turn the temp knob to cool side, disconnect the pos side of the battery for a couple of minutes. Reconnect the battery, plug in the bend motor start the car and turn the temp control to heat side. If this does not work remove the motor and repeat. the motor my be jamed. I had the same problem, this might be a cheaper way to fix this instead of the dealer. PS if you remove the blend motor, be carfull to look at the orientation of the spring on the shaft of the door in case it pops off.
