Ford Explorer Air Conditioner and Heater Problems



  • 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?
  • I have a 2000 exployer and I cannot locate the lever for the blend door
    is it in a different position than the other model years? Next I have no fan movement
    In the front of the vehical . Only in the rear. I had high and next high speed up to
    a week ago. Has a fuse blown? when inside the dash I wiggled the wires to the switch
    but did not get the fan to work. Are these problems related? This is now critical for
    de-icing and defogging let alone heat.

    Sounds like your front fan motor is burned out. Could be a fuse, but more likely the motor is gone. This is independent from the rear air, which has its own fan motor. Your front one is easily replaced from under the hood. About 4 screws will open it up, you pop in a new one. Good luck!!
  • Did you find a solution to your heater problems?

    Your description of the problem is identical to my issue.
    I have a 2004 Ford Explorer 4.6l Eddie Bauer with Dual Climate Control.
    I purchased the HeaterTreater Blend door thinking it would correct the problem, however after I took out the actuator motors (the dual climate control system has TWO), I discovered the BLEND Door was find and both actuators were working properly also.
    I want to know how you were able to fix your problem.

  • Hi. I have a 95 4x4 explorer with v6 engine. I have owned this car since new and it has provided me with excellent service. Recently, I was bringing it home from my mountain cabin, outside air temp was 9 F. If the defrost was on, the engine temp gauge would shoot way to the right, near the red zone. If the defrost was turned off, temp dropped down within seconds to normal. I cycled this several times and got the same results. If I ran the air conditioner alone, it would not do this. Coolant level is normal. New heater core, about 1 year old. Any ideas??
  • I'm having this issue right now with my 2003 explorer. thank you for posting this fix. I will try it today.... hope it works

    I have a 98 Explorer, I have heat coming out of the vent near my feet when all the climate controls are off. This works fine in the winter but its starting to get warm and I no longer need cold feet. Any help would be greatly appreciated by me and my right foot/shoe.

    Put your climate control in recirculate position and then turn it off.
  • my heat stays on, no matter what position the knobs are in. Constantly blowing warm out.
    Also when I purchased the vehicle, the dealership said they needed to add refrigerant. It lasted only two weeks at minimal useage. I added 2 more cans and no cold at all. HELP Im hot all the time!!

    the temp door actuator motor is most likely the problem,look behind glove box(allow glove box door to open beyond the stopping point)let the door swing down,the actuator motor is located on top of the blower box toward the middle of the vehicle.It has a single plug in(small)with multi0wires on the plug in,the actuator motor is flat,and is held in with three hex head screws,the rear one is the hardest to get to,this motor is not moving and changing the temp,to cold,it is staying in one spot on the hot side.

    When I turn on my heater or air conditioning a faint thumping / clunking noise starts and gradually gets louder and is very constant. The noise is triggered when the temperature guage is turned to max heat or max cold and can be stopped by turning the knob 1/4 turn in either direction. There doesn't seem to be a lot of air flowing out of the front vents - but the heat and air conditioning are both working. Haven't checked out the rear climate controls yet. Any suggestions on what the problem could be would be greatly appreciated...also is this an easy / inexpensive fix for someone with basic auto mechanic skillls or a job that should be left to trained professionals. Any advice is greatly appreciated. Thank you.

    Sounds very much like a stuck Blend Door under the dash. It's not easy, and is expensive, because so much has to come out to get to it, and then be put back correctly. Doubt you can do it, I couldn't and I'm reasonably mechanical. But there is no other choice if you want it to work properly. Sorry to hear you have this problem, it's a big pain... :sick:

    We replaced the blend door with one from company on Ebay, was quite a job!
    Works good now- you have to stand on your head to do the job!
    Took us about 4 hours!

    I have a 2004 Eddie Bauer Ford Exploer. Our AC blows warm/hot air and sometimes cold. The thing is, the cold air will be come through sometimes. We can go for days with it blowing the hot air, then all of a sudden the cold air will start to blow(always while driving). The cold air will last for the duration of our drive and the when we turn the truck back on it blows warm air again and the cycle begins again. Where do I begin to even diagnose where the issue is?

    Sounds like same thing as my #378 response---bad blend door--plastic hinges go bad
    on the blend door and will not respond to the heater,air motor control .

    Or, it could be a bad expansion valve. A little $3 part that can raise havic if not working correctly. It's in the hot line some on the passenger fender, along the top.

    I have an F250 diesel, 1999. The A/C will work great at times and blow hot air at other times. I can not find any coorelations to speed, rpm, etc. It will blow cold air for 20 - 30 minutes sitting in a parking lot, when I take off it blows hot air, 5 to 20 minutes later it will blow cold again for a few minutes. Always back and forth. The system is fully charged.
    Any ideas?

    I have a 98 Explorer Sport. The Air Conditioner seems to work on short distances, but on long trips, stops blowing as hard and doesn't blow cold. Sometimes when I turn the car off and recrank it, it works fine again. Took it into a mechanic and it wouldn't act up for him so he said he could not fix it. Would love to know what's going on with it. Thanks for your help.
  • I have a 1999 Ford Explorer Sport. My air conditioner works well when it is on regular A/C. But when I switch it to Max A/C, the air flow almost stops completely. Before the problem started, Max made the air flow stronger AND colder. I am guessing that there is a switch not moving a flap that should be moved. Does this sound right, and if not, could you please tell me what it could possibly be.
  • nvbankernvbanker Posts: 7,285
    Again, could be a faulty expansion valve, a very easy and cheap fix if you know how. Also could be a vacuum problem with your blend door in the dash. A horrible and expensive repair if you know how, and impossible if you don't.
