ok i figured out what the prob was in my 2002 ford explorer. we thought that our blend door was the problem, but turns out it wasnt. the knocking noise you are all hearing, or at least what i was hearing, was the gears in the blend door actuator, which is connected to the heater controls, which makes the blend door move. we took out the box, which in my truck, was located on the drivers side
It is really kinda hard to get to, but if you can manage to get to all the screws loose great! we only had to take off the panel near the floor to get to it, but when you get the screws loose, and take out the box, you have to open it up and look at the teeth of the gears, if they are not broken off or chipped then thats not your prob. my gears were broken. you can do 1 of 2 things. if the gears are broken, you can go to an auto store and order a new actuator, which is around 40 some dollars, and then just put the new box in, replace the screws, and your finished....lol i actually have a quick fix solution while your waiting on the part to come in. when you open up the box, there is a piece that sticks out of the box, that fits into a slot in the dash that connects to the blend door. if you take that piece out of the actuator, just that one piece....and stick it back in the hole in the dash, you can manually turn the heat on by flipping the piece either forward or backward, but the blower will have to be turned on for it to stay on. but this is a quick fix and it will give you heat, until you get that box replaced. if you have any questions, or this doesn't make sense let me know...
I posted this last year sometime and I hope this will help you, this problem has not come back for now...they have the part I am talking about above at any auto parts store for 40 or 50 bucks, which def beats the $700 your talking about...I also put in there a quick fix to help you until your part comes in, or if you just don't have the cash. Please email if you have any questions

Hi Gunner, Elvoolz is exactly right, in fact I probably told the person what to do when his was out. Be sure to have your Ford running, parking brake on,and the temp control all the way to hot so it will continue clicking or thumping. The clicking helps you locate the lever, as it's a bit hard to find. Don't give up. Another tip is the lever is very close to the verticle dash brace that you will feel under there.Let us know how you make out. Clusterbuster.

Wow! I've got a 2006 EB that is doing exactly what you are all talking about. Haven't seen anything that addresses the problem until I stumbled on this forum tonight. Mine is doing just about everything that everyone has talked about here. I've located the general area of the problem and the method to choose either hot or cold... but not a happy medium. I can get hot or cold when I manually switch... but no in between. Lots of clicking and thumping.
So... there's this "blend box" were the amount of cold air and hot at is controlled with a motor and some kind of interior door.? I have located the blend door actuator on the drivers side and decided not to tackle that monster until I have more information. Very difficult to remove. I've also located a lever directly across from the motor on the other side of the blend box on the passenger side. It is accessible a lot lower than behind the glove box. Mine is a little higher than just behind the middle console cover that is removed next to the passenger floorboard. Its hard to find. It basically sticks Up when the temp control knob is in the cold position and can be moved, towards you and down, when the engine is running, in park and the as other have described for heat. This will control the hot and cold so at least I can get it to work.
I've known that this problem is going to cost me a fortune since it happened. and I'm pretty good Mr. fix-it. I think I'll look at the blend door fix from heatertreater.net and also talk to the part dept about the blend door actuator replacement and see if the problems I am having are symptomatic of what they might see regularly. I'm also going to see if I have simply missed a lever or vacuum hose that is broken. It sounds to me that Ford has multiple problems here and I want to make sure I get the right one. I'll keep you posted as I find out more.

I have a 2003 Explorer XLT and currently having the exact same problems. I started with the blend door fix from Heater Treater, last March. I recently started snooping around for the reason that the heat doesn't make it to the dash. Here's what I found.
If you pull the instrument cluster,(speedo and and fuel guage and things) out of the way. To the far right there will be a little hole. Shine a flashlight in the hole and move the selector for the hvac controls to defrost clicking one at a time work your way to off. There is a vaccuum actuator there that connects to a door,(similar to the blend door), mine is broken off. If you see a lot of movement in and out as it moves front to back, I bet you have the same problem.
I am working right now to see how involved this will be to change. It looks like you have to remove the whole dash. I will let you know what I find.

I too have a 2006 EB, but my heater does not work at all. My air conditioning works awesome and gets real cold. However, when i change the temperature off cold (anywhere off the blue), the console sounds like it's knocking or clicking. i tried running the heat with the knocks to see if it works, and it doesn't. i called my warranty people, and this part isn't covered (shocker...). I'm sure it'd be at least $1,000 to replace a $40 part, and i'd rather be bold and do this myself. Does anyone have a step-by-step instruction on how to change this thing out? I have the Hayes book, and it will only get me as far as taking off the console. Is this the blend door or do I try that heatertreater.net thing i found on youtube?

I also have an 03 explorer, performed the Heater Treater fix last winter and have had piss poor heat ever since. Have torn it down 3 times now. I get good heat on the floor, cold out the upper vents. Barely good till -10c then unbearable past that. I tried your fix and i cant determine what part you are talking about.
With the glove box open and looking in to the left there is a steel bar hooked up to a vacuum actuator that points forward towards the rear of the car. This actuator is triggered by the movement to defrost and appears to be working a-ok. Also in that extremely sharp and hard to see space is the exposed hinge of the blend door that has the lever on it that triggers the heater core when in full cooling mode.
What am i missing? Could someone take a picture - i desperatly want my heat back as its getting cold up north!

I would HIGHLY suggest against the HeaterTreater fix if you are only getting the clicking problem. Just look on the Explorer Forums for posts about replacing the actuator, its a pain, but only 1/4 the hassle of replacing the blend door. The blend door ultimatly causes the actuator motor to bust, however for the 100$ for the actuator. I'd replace 4 before having the pain of the blend door i've endured. (Others have as well) The problem is that after replacing the door, something happens and nobody seems to know what, but the heat out of the upper vents stops working and if you are in a cold climate this is unacceptable. I had to destroy the old door to get the new heatertreater one in so there's no going back now .

I too have a 2002 Exploder, and I'm unable to locate this blend door actuator. I can hear it behind the Center Bezel. Where exactly is it and do I have to remove the Center Bezel and/or Knee Bolster.

When I replaced the actuator, we had to take off the panel underneath the steering column, as well as the paneling along the console in order to reach the actuator. I have to be honest...it is a really tight fit and really hard to see, but being that I am a woman it was a lot easier for me to squeeze in there haha. You will have to lay on your back on the floor board on the driver side and use a flashlight to look up into the dash, almost next to the radio, and it is a white box, i will put some pictures here to help.
I really hope this helps you
If not, please feel free to get ahold of me!
