2008 Mustang GT - AC Knocking

I've searched through the forums here and noticed several posts dealing with this issue. I believe from what I've seen thus far, my issue appears to be a problem with the Mode Door Actuator - Panel/Floor Door, seen here:
Ford Service Manuals - REMOVAL AND INSTALLATION

I checked what I believe to be the three actuators accessible from behind the glove box and disconnected them one at a time and the knocking persists.
I want to check this one by disconnecting it, however I'm unsure exactly how to access it.

Can anyone provide some pictures or a more detailed write up on how to get at this bugger? From what I've read so far, this is the most difficult of the four to access and of course it's the one that probably needs to be replaced.

Thanks in advance,

h87


Edit: I just noticed that I posted this in the v6 forums, oops! Any help would still be greatly appreciated!

Keep searching AFM, I do remember reading a good thread on accessing the one behind the cluster. Seems you have to really snake your arm up there from the driver's side.

It's on the left side of the console.
Way up High.
Put your back in the driver's footwell, your head near the accelerator pedal.
Flashlight in hand.
It's above the heater/ac box.
Very easy to disconnect it's electrical connector, to determine it it is the one making noise.

And yes there are four of these actuators total..as shown in the manual you included in your post.

Air inlet door
defrost door
temp blend door

And this left of console one....panel/floor door

Thanks for the info. I'm going to look into this today. I'll update with my findings!

That did the trick!
I was able to find it and disconnect it. When I flipped the ignition into on and fired up the AC, no knocking!

Thanks again for your help in accessing it, I think I can take it from here.

Well, it looks like I spoke too soon.
I got the part in and it looks to be the correct one, but I'm having a hell of a time getting the old one out.
There's so little room in there, how the hell do I get to the top friggin screw?!
Any advice on how to do this?

Okay, well, I got frustrated and broke off the top tab with the screw hole, good thing they have an unused screw hole on the bottom I can use for the new one.

So, now my problem is this: I ordered the part number referenced in the service manual I linked in my first post and it matches the part number that I took out of the car, but the electrical connectors are visibly different.
The old one has a different pinout and is keyed differently along the inside of the socket.

Bottom line is I can't use the existing electrical connector in the new part.

Anyone run into this?

I've read lots of threads on AFM about replacing vent actuators, your's is the first about the connector being different. Where did you purchase the actuator? If it was me, I'd be on the phone with a Ford dealer parts counter and find out if they changed the actuator for a different model year and go from there.

Thanks for the tip. Unfortunately the dealerships near me are all closed for the day, but I'll call tomorrow and update with my findings.
