Title: "How-To" Replacing Blend Door Actuator Instructions

I did this last night in my MKS, and I have a 3 out of 10 skill level. The whole procedure took me about 15 minutes thanks to tips from others on this forum (particularly Jack Skellington and crash712us ).

The symptoms: Clicking/tapping noise coming from the dash area near the passenger side when the car is on and the climate control system is on.

The Part: Door blend actuator (part number: AA5Z-19E616-C) . I got mine on ebay for $19.00 shipped. It is a genuine Motocraft part. Here is the link to the part and a photo I took of the part.

http://www.ebay.com/itm/NEW-OEM-FORD-LINCOLN-MERCURY-OEM-BLEND-DOOR-ACTUATOR-AA5Z-19E616-C-/280886764325?forcev4exp=true&forceRpt=true (http://www.ebay.com/itm/NEW-OEM-FORD-LINCOLN-MERCURY-OEM-BLEND-DOOR-ACTUATOR-AA5Z-19E616-C-/280886764325?forcev4exp=true&forceRpt=true)

Directions:

Fully release your glove box door so it "hangs" down. There are two clips/bumper stops on the right and left side, towards the rear of the glove box interior that need to be removed to do this. It is the identical first step you take when changing the in-cabin air filter. Once the door drops, you will see this:

(https://i.imgur.com/cLA2mSBh.jpg)

You will clearly see the white part. There are 2 clearly visible hexagon head screws holding it in. Remove them. Then, undo the electrical clip fastener. The part will now be free from the car.

Connect the electrical connector to the new part and try to insert the white gear shaft (attached to the rear of the actuator part) into the opening in the car to re-secure the part, using the 2 hex head screws, to the car.

In my case, the gear shaft was not properly lined up. You will note from the photo below, there is a small flat area on the gear shaft - it is not perfectly symmetrical, so it can only go in one way. If it does not line up, start the car and fiddle with the temperature control (hot/cold) , as that will turn the gear shaft clockwise and counter clockwise. Play with it until it is in the right position to insert with the 2 hex head screws lining up. This is very easy, but takes a minute or two to fiddle with to line it up. See non-symmetrical gear shaft below - the "flat" area is facing you.


(https://i.imgur.com/stE5W78h.jpg)

Once it is lines up, inserted, and the screws are back in, simply put the glove box back into position and re-insert the two rubber bumpers/stoppers. And, you are DONE!!! $19.00 and 15 minutes or less with nothing more than a hex head driver saves you a trip to the dealer.

P.S. If you have not changed yourecabin air filter in a while, You might want to do that before re-securing the glovebox, since the filter door is completely accessible.

The Culprit:

I opened up the broken actuator and the photo is below. You can see some inner gears are work down and broken in the center of the photograph.

Hope all of this helps a fellow member! :)

Mine has been doing this for about 3 months, but so far I still have A/C.  Will get the part and fix!

Used your link and ordered part.  Comes from Tasca - free shipping.

Yeah, I never had any failure (like A/C not working), just the annoying clicking/knocking.  If you have any questions when installing it, shoot me a PM!

You know, I haven't heard of anyone having problems with the blend door on the driver's side...I take it that one may be harder to access and change?

  I found in changing three of the four, that the passenger side (note to the left of the easily accessible white one) is by far the worse one to access. You can see the lower fastener bolt head in the photo.  I took a few breaks during the install as to not damage other parts of the car or myself lol.

I got the Blend Door Actuator from Tasca this AM.  Grabbed a bunch of tools an proceeded to vehicle.  Dropped Glove Box Door by pushing in on both sides. Presto!!! everything fell on the floor, just like I planned.  Then I turned on Flex and got the blend door actuator to click, and could feel that it was slipping.  Next... I realized I had all the wrong tools to remove it.... BUT I did have my trusty little socket set on the floor that had been in the glove box, that I used to remove MCT sensor and most other under hood parts.  Grabbed the correct socket the first time and had it out in about 10 seconds. Popped in the new one and attached it with 2 bolts/screws I removed.  Plugged it in and replaced glove box and everything in it.  That actually took more time than replacing the blend door.  Once repaired, I proceeded to test it!!!  I always do it this way, so I have a 50% chance of having to re-do what I did!!!! But disappointingly, it worked, so I was almost done.  Went back inside and put away all the tools I didn't need (had all tools already in Flex!) and then proceeded to take the old actuator apart.  The same big gear as shown in pix above was missing 1 tooth.

If I were doing this again, I could do it in my sleep in about 2 minutes or less! Very easy and no access issues!

My HVAC system "Clicks" once, loudly, every time the system is turned on and then again when it is turned off. Sounds like the recirculation actuator motor. Is there a fix for that too?

It could also be your door blend actuator making the click sound when turning on and off,relativly a cheap and easy part to install,while you have the glove box open install a new cabin filter.

No worries on the cabin air filter. I did that in June when I got the car.

I notice it does the click when I push the recirculation button too.

Post by: SHOdded on February 26, 2015, 08:53:03 PM
Can you localize the sound?  Normally an actuator is more of a ratcheting sound, but an early stage could be a click.  Wasn't there a tsb for the climate control module?

Wish I scrolled down farther and saw this. I ordered AA5Z-19E616-A thinking I needed it...I actually needed AA5Z-19E616-C (the one right behind the glove box).

Now that I look back, the very first post on here has it spelled out for me in plain English. Now I'm trying to figure out how in the heck I ordered the wrong part......I need a beer

I replaced the one behind the glove box, no problem. But, I still have only warm air on passenger side, so it must be the one on the passenger side of the center console. Has anyone replaced that without swearing? I can get one bolt off, but there is some big plastic thing in the way. Can't see the other bolt or the electrical connector.

  It may be the actuator also on the passengers side, located to the left of the unit behind the glovebox door. It is the one that fixed the issue in my 2010 after first replacing the glovebox unit to no avail.

 Black plastic housing as opposed to the white plastic.

Right...that is the one I need to change. In your picture, it is to the left, and you can see the bottom bolt. There is some plastic monstrosity in front of the actuator and it seems impossible to get to the other bolt or electrical connector without breaking something.

  Yes I did swear a lot  in removing it lol.  The mechanic at Tasca providing install advice was surprised I was able to pull it off.  One of the reinstall tricks I do remember was to dremel the far side attachment loop that the bolt holds down in like a hook with enough clearance to be able to reach up and start the threading of the bolt then "hang" the hook over it enough that you can tighten it without loosing your mind.

What a pain....the part I ordered is #AA5Z19E616A. This is actually the defrost/panel blend door actuator. The part I am trying to replace is #AA5Z19E616C....except the old part is labeled AA5Z19E616BA

So annoying. Now I have ordered all 3

I quit. The passenger side is going to stay hot for a while. Time to eat some hard boiled eggs and ham. Happy Easter

my a/c temp feels the same between 60-73*. Temp gets warmer at 74* and colder at 73 again.

doesn't feel like its blowing as cold as it should on both sides I rarely use the dual climate. Could this be a blend door actuator symptom ?

Post by: SHOdded on July 30, 2015, 08:23:32 PM
THere should be a self-test that can be run, and it will be in the FSM.  I have my Edge's FSM, not sure it will work the same way:

Electronic Automatic Temperature Control (EATC) Module — Diagnostic Methods

The electronic automatic temperature control (EATC) system must be diagnosed by first retrieving any DTCs, if present.

An on-demand (hard fault) DTC indicates that the fault is currently present. An on-demand DTC suggests a wiring fault, disconnected connector or component failure.
A continuous (intermittent) DTC alone (corresponding on-demand DTC is not present) indicates that the fault is an intermittent condition and may not be currently present. A continuous only DTC suggests a poor wiring connection, loose pin or terminal or intermittent component failure.
On-demand (hard fault) or continuous (intermittent fault) DTCs can be retrieved using a scan tool. If using a scan tool, refer to the scan tool operating manual.

On-demand DTCs can also be retrieved by carrying out the Electronic Automatic Temperature Control Module On-Demand Self Test. To retrieve and/or clear continuous DTCs, carry out the Electronic Automatic Temperature Control Module — Retrieve Continuous DTCs procedure. Always carry out the Electronic Automatic Temperature Control Module On-Demand Self Test before retrieving continuous DTCs.

If no DTCs are present, GO to Symptom Chart for the appropriate diagnostic action.

EATC Module On-Demand Self Test

The EATC Module On-Demand Self Test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous DTCs can be cleared when exiting the EATC Module On-Demand Self Test. Make sure to retrieve continuous DTCs by carrying out the Electronic Automatic Temperature Control Module — Retrieve Continuous DTCs procedure before clearing any continuous DTCs.

The EATC Module On-Demand Self Test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns.
The EATC Module On-Demand Self Test will detect concerns in the system control functions and will display on-demand (hard fault) DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4°C-38°C (40°F-100°F) when carrying out the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.
The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test is activated.
To enter the self-test, press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within 2 seconds. The display will show a flashing "----" for a maximum of 20 seconds, after which "8888" will be displayed if there are no on-demand DTCs present. If DTCs are present, the EATC module will display the on-demand DTCs. Record all DTCs displayed.
If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the Electronic Automatic Temperature Control (EATC) Module DTC Chart and follow the ACTION for each DTC given.
If a condition exists, but no DTCs appear during the self-test, GO to Symptom Chart condition: The EATC System is Inoperative, Intermittent or Incorrect Operation.
Always exit the self-test before powering the system down (system turned OFF).
Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

EATC Module — Retrieve Continuous DTCs

The EATC module will retrieve only continuous (intermittent) DTCs when carrying out this procedure.

Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
To retrieve continuous DTCs, press the OFF and DEFROST buttons simultaneously and release, then press the RECIRC button within 2 seconds. The display will show a flashing "----" for a maximum of 20 seconds, after which "8888" will be displayed if there are no continuous DTCs present. If DTCs are present, the EATC module will display the continuous DTCs present. Record all DTCs displayed.
If any DTCs appear, carry out the diagnostic procedure. Refer to the Electronic Automatic Temperature Control (EATC) Module DTC Chart and follow the ACTION for each DTC given.
If a condition exists but no DTCs appear, GO to Symptom Chart condition: The EATC System is Inoperative, Intermittent or Incorrect Operation.
To exit and retain all continuous DTCs, press any button except DEFROST. The EATC module will exit the retrieved continuous DTCs mode and retain all continuous DTCs.
To exit and clear all continuous DTCs, press the DEFROST button. The EATC module will exit the retrieve continuous DTCs mode and all continuous DTCs will be cleared.
Always exit the procedure before powering the system down (system turned OFF).
Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

Electronic Automatic Temperature Control (EATC) Module and Electronic Manual Temperature Control (EMTC) Module Cold Boot Process

The purpose of the cold boot process is to allow the EATC or EMTC module to reinitialize. To carry out the cold boot process, follow the steps below.

NOTE: EATC only.

Clear the DTCs.
Turn the ignition switch to the OFF position.
Disconnect the EATC or EMTC module electrical connectors.
Inspect module connectors for:
corrosion.
pushed-out connectors.
incorrectly seated connector.
Wait one minute.
Connect the EATC or EMTC module electrical connectors.
Turn the ignition switch to the ON position.
Select any position except OFF on the EATC or EMTC module.
The EATC or EMTC module will now initialize.

Sorry to dig up an old thread, but how do you know which one needs to be replaced? If I'm understanding correctly, there are 3 of these, 2 behind the glove box and 1 underneath the steering wheel. Is there a way to tell which one is bad or do you just replace them all? (I.e. no heat on passenger side = x actuator)

Been alot of talk in this thread about how hard it is to get the actuator out that is buried by the electrical connector.  Any tips on how to get that connector out of the way so you can access both fasteners and remove the actuator?
