How to replace a mode door actuator on a 2010 Ford Edge

that is real easy , but the tests take skill sets.

1. the drive motor is bad, (actuator )
2. the wrong actuator used or installed wrong.
3. the controller to it is bad.
4. the blend door is jammed. (we turn it by hand to learn that)

stuck in heat mode, blocking AC. cool. sure.
a very common problem
some after marked actuators are junk, is common.
scan the OBD2 port for HVAC errors yet?
check all fuses first?

Try motorcraft or SMP brands, on this car. SMP is what I use.

a JURYRIG:
now one skill lots of DIY guys do even all hot summer
they remove the blend door actuator and then hand spin it
to full closed ,casing max COOL to happen and does.
then keep it there somehow, if will not stay there until winter.
I call it the hillbilly fix. (with love )
motor craft says
(get door A closed) receirc
get B , bend set to block heater core
get C mode as you want, dash/vent/floor.
B can be forced on some cars easy,
the bend door has axle shaft and and adaptor cupling on some
that make it easy to hand turn the axle and to even bailing wire hold it if need be..
or dig my hack #2
take the old actuator and rip it all apart and jam it to cold.
then put it back in, with cold max, HACKED.
and last hint #1
some AC the Actuator must relearned. as the service manual so directs.

recheck your wiring and test actuator

Do you have separate heat/cooling controls for driver and passenger. If so, you have two blend doors/actuators.

No vacuum controls on this system . Electronically controlled mode door actuator . (electric) You mite find a video on youtube for replacing mode door actuator .

mode door actuator inrear Hvac . The clicking is the actuator slipping it's gear's . Plastic gears break ,wear out etc....
You have to take right rear trim panel out to replace it >

Temperature Blend Door Actuator - RH, EATC Removal and Installation

1. Remove the RH floor console finish panel.

1. Lower the glove compartment.

1. Disconnect the RH temperature blend door actuator electrical connector.
2. Remove the 3 RH temperature blend door actuator screws.
1. Remove the RH temperature blend door actuator.

Deep inside the dash behind the glove box.

If the driver's blend door actuator has failed completely, or the wiring to it is damaged, you will not hear any clicking. Check for appropriate voltage at the blend door actuator, and determine from there if it's the actuator or the control unit.

Automatic or manual HVAC ?
Air Distribution
The HVAC control module controls the distribution of air by the use of a mode actuator. The modes that may be selected are:
• Defrost
• Defog
• Panel
• BI-Level
• Floor
The mode actuator is connected to the mode door by a cam type linkage system. Depending on the position of the door, air is directed through the HVAC module and distributed through various ducts leading to the outlets in the dash. If the HVAC control module detects a fault with the mode door the HVAC control module will try to drive the actuator for a predetermined amount of time, to defrost, which is the defaulted position for the mode door actuator. When the mode switch is placed in the defrost or defog positions the A/C is commanded on and the recirculation door is moved to the outside air position to help reduce window fogging. A/C is available in all modes and recirculation is only available in the panel and bi-level modes.

On the automatic HVAC the whole dash does not need to be removed !
Caution: In order to avoid actuator damage, DO NOT apply power to the actuator when it is not installed in the HVAC module.
Preliminary Procedures
Remove the instrument panel insulator - right side. Refer to Instrument Panel Insulator Panel Replacement - Right Side.
Remove the instrument panel (I/P) compartment. Refer to Instrument Panel Compartment Replacement.

Procedure
Disconnect the electrical connectors.
Re-calibrate the right temperature actuator. Refer to Actuator Recalibration.
The dash doesn't need to be removed for manual HVAC either ! Take out the glove box an the insulator panel ! Do you know what the insulator panel is ? There could be a video on youtube ! This repair would only take a half hour at most .
