Ford Explorer Air Conditioner and Heater Problems



  • 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 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 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!

  • my explorer has freon ,, compressor runs,, everything turned off but hot air is coming out ,, no a/c at all any ideas ??
  • I have a 2000 ford explorer and for the past two years or so, the heater has refused to blow heat. Apparently it had the same problem before it was given to me, but they took it into the dealership while it was still under warranty and when they got it back it worked again. I had it for about a month, and then all of a sudden it would no longer blow heat. It blows just great and the AC works awesome, and even when the temperature gauge reads that the engine is warm it still refuses to give me some warmth. Any suggestions?
  • Thanks guys!!!! It worked just as you stated:) I came to visit my sister who is having the same problem. Pulled the glove box out, stuck my hand in and and pushed down-heat came out the dash. It took about 5 minutes. Just stick your hand where it can fit towards the dash. Thanks again!

    I have a 96 Ford Explorer (EB) with a heater that will not blow out warm air. The feed and return water hoses are warm to the touch, the vacume lines appear to function correctly, and the damper opens and closes. please help...
  • I was wondering if you have figured out what the problem was with your explorer and how much it cost you to fix the heater becuase i have the exact same problem with mine and its start to frost over in the morning and it sucks driving in the morning without a heater.

  • Never did fix mine. The temperature actuator motor gears are stripped in the actuator. You should drop the glove box door and reach in to the left and find a lever that opens and closes the blend door. Pull back on the lever toward the rear of the car and it will open the door and provide heat. The temperature knob has to be set all the way hot for this to work. It may take a while to find the lever, but it is there. You may want to have the vehice running and you should hear a ticking sound . The ticking will direct you to the lever. Hope this helps. It would be very expensive to fix at a shop. Remember to not move the temperature control knob after you pull the lever back, or you will have to do it all over again.
  • I have a 2004 explorer and the heat works great in the rear and third row, but all that blows out the dash is cold, I read your other listings and located the lever when I dropped out the glove box this fixed the problem for about a week, then I heard the clicking again and once again it was cold, so turned the lever again and nothing still cold, what do I do now?

    So the actuator on the driver’s side controls that lever behind the glove box on the passenger side? So if I replace that then that lever will stay down?
  • The actuator is a geared unit fastened to the heater unit under the dash. It is quite a job to replace it, requiring removal of the console and other parts.I don't know the cost of the actuator, but imagine it is expensive. I've heard of costs up to a thousand dollars to fix what you are talking about. For me, I keep the lever down, and bear the extra heat by lowering a window a bit. In the summer I keep the temp control on cold for the A/C when I need it. Don' t plan on keeping mine for too many more years.
  • Thanks to all contributors on the heating problem. I finally found the lever to open the blend door on my daughter's 2003 Explorer. It was right behind the medal brace on the left side of the glove box with my hand just below the small bend on the brace. I realize that this is a temporary fix but at least my daughter will not have to drive 300 miles without heat. Thanks to all!!!
  • ok i have checked the blend door it works but there is no heat all the hoses get hot the heater core is getting hott what else could cause the heat not to work oh yea the blower motor works to
  • If everything is working properly, hoses are getting hot, temperature actuator is working, blower etc, then flush the heater core. More then likely it has build up from minerals in the water and is clogged up. Remove the hoses and flush the core from both ends for several mins until you have clean and adequate water flow.
  • I too have a 2000 Explorer and in addition to the NO issue I do not have a fan which
    compounds the problem I believe it is in the switch as it works on only High and next lowest
    speed for the summer. Now with winter and the need to defrost or de-ice it is critical.
    Could it be a fuse or loose connection?
