Blend door actuator?

Hello,

You should be able to change the blend door actuators out by removing plastic covers and maybe some bracing. Here is a guide to help you step by step with instructions in the diagrams below to show you how on your car.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

My heater is out in my explorer, the AC works fine and so does the blower. I hear a loud knocking noise anytime I move the dial to heater. I was told by a mechanic that the blendoor was broken. If I remove the radio, could I fix this part and reach it?

replacing the blend door is quite expensive. I had mine replaced last winter and it cost $300. Part is only $12 but they have to take the whole dash out to replace it.

I would get a service manual and research this further...if it is the blend door it is not accessible behind the radio, it would actually be behind the glove compartment.
If the blend door and/or blend door actuator IS at fault you should hear the blower motor come on, but would get either no air flow or just cold air through your vents when the heater is on. - I would also check to make sure both of your heater hoses going into the dash through the firewall are hot to make sure that we have good flow through the heater core........

It's accesed from the drivers side lower panel....go to heatertreater.net for pics, video, and kit.

I am having difficulty with the blend door on the heater not fully engaging when I switch the temp control to a colder temp. The door seems to start to change and then pops back to its original position. How do I access the blend door to see if an actuator is malfunctioning or see if something is sticking? This problem gets worse the higher the fan speed.

Hi:

I recently replaced a door blend actuator in my wifes 03 explorer. I couldn't find any other way to get to it besides removing entire dash and surrounding interior pieces...After hours of fighting I finally got the old out and new in. while putting the dash back together and putting steeering column up i broke a part of the wire harness that goes into my odometer. I believe theres 5 total that clip into the odometer. The one that broke is a large on furthest inboard, or towards the passenger side. I didnt count but looks like about 20 wires total. Only one wire came off but the part where the wire goes into is busted. Also, there is like 2 or 4 extra spots open on that side of the clip so im not sure what one the wirewould go into anyways...Any idea the name of this clip the wire harness meets? or, a wiring diagram of any sort? Ive been searching the web for hours now. Im not having any luck, so any help would be greatly appreciated.

You pulled the whole dash !! My aching X$$, that was a S.O.B. to do !! All because of a piece of "plastic" on the Blend Door Actuator became "brittle" when subjected to "heat". Those Ford/Lincoln/Mercury design engineers are real winners!! I am quite sure you are referring to connector (#1) the (Thin white connector) on the far right in the picture below.

Does your rear view of the instrument cluster look like the one pictured below? (Passenger side Left) Connector #1 (Wide Thin White Connector) connects to the very top #1 in picture below. Connector #3 (Small White Connector) connects at the bottom #3 in picture below. Connector #2 (Wide Thin Black Connector) connects at the top #2 in picture below just before where the small circuit board protrudes out.

Hopefully we are both on the same page in reference to the instrument cluster. Let me know if we are looking at the same instrument cluster and I will get right back to you and help you get those wires connected so you can be done with the headache. Rick

Ya, was a pain, but I got everything back together and everything seems to be working. but i dont know how long the wire will stay in that slot without being locked in. yea it seems to be the same cluster, I didnt completely tear the cluster apart so Im not positive. number 1 looks like the one, ive looked all over for someone selling those pigtails but hasnt been any luck. its my wifes truck so im trying to get it right i dont want her headlights to go out or something while she is driving. maybe this weekend im going to go to the boneyard and see if i can get one off an explorer there...Will probably be as big of a pain as taking the dash apart lol...Cant believe I smashed that clip. I just did basically the same job in my bravada a few months ago for the heater core. I cant find any wire diagrams or anything anywhere. So hopefully I can find a totaled explorer around the same year...Do you know what models or years the instrument cluster changed? or if it even has?

I put a 2001 instrument cluster in my 1999 Mercury Mountaineer. Everything plugged in the same identical way, I didn't have to fiddle around and change anything. FROM THIS 1999 BLACK GAUGE CLUSTER

TO THIS 2001 WHITE GAGE CLUSTER

I think, "but not sure" the instrument clusters changed starting in "2002" - they started with some digital readouts like mileage in the lower right corner.etc. I would say you will be good from 2002 - 2005. I would ask them at the bone yard what years are compatible with your 2003, they will know without a doubt. Maybe you will get lucky and find an explorer with the instrument cluster already removed. Just make sure it is the right year and cut the connector you need from the harness- then all you will need to do is connect the same color wires to your 2003. If they don't know at the bone yard, just poke around and find an "identical" instrument cluster and you will be fine. I would solder the wires together and cover them with electrical tape to be safe. If you have any questions you can get back to me anytime at all. Just private message me and I will get right back to you. Good Luck; Rick

I figured out what the wire is for. It goes to the interior light for right blinker. Not really to important will prolly just tape it up untill summer and then try to fix it. Thanks a lot for the help and advise

Does anyone know how to access the blend door, and if u even can without pulling the entire dashboard off? and if i were to take it in how much is a fair price to get my heat back? Thank you Kindly!!!1

i have an 02 explorer with the same blend door problems as anyone else, i removed the actuator blen door motor because i thought it would fix the problem of no heat, nope, just blows freezing air now, does anyone have a quick fix so i can get heat back, i am trading it in after winter and dont wanna replace everything,

The only thing you can do is tie the door in the position you want it.

Joe do you have any idea where the heater core speciffically is i cant find it

If you look under the hood (firewall), you will see where the heater hoses attach on the firewall. They attach to the heater core. It is on the inside of the vehicle where the hoses attach.

Let me know if you find it.

joe i think i can see it but what door covers it to flow heat, i dont see anything in front of it

joe i think i can see it but what door covers it to flow heat, i dont see anything in front of it[/quote:ee8e3f8a62] ok joe i got into the dash and everything tried moving around the vent doors to try and circulate heat, still no heat anymore ideas you might have

I need you to check something. With the engine at operating temp and the heater on, do both heater core hoses get hot?

yes joe both are hot.i also checked the coolant flow valve that is also operating correctly. I have no coolant leaking from the heater core or anything

The only thing left is the blend air door. It must not be opening toward the heater core. If the heater core hoses are hot, then the core must be hot. Something is stopping the air from passing over it. That would be the blend air door. That is all that is left.

Try checking it one more time.

Let me know.
