Ford Explorer Air Conditioner and Heater Problems



  • Bought the car and loved it, drove for a few days with no problems except for the beer smell. One cold cold morning must have been 19 degrees out I noticed the ride to work was a little chilly..30 miles. I took it for not letting it warm up enough and went about my way..
    The next day it was 19 degrees out so I started it early so it was plenty warm. I went out at 7:30am and let it run with all the heaters on 10… full blast front and rear… it ran for 40 minutes!... still froze my [non-permissible content removed] off. I started getting a real bad pain in my right leg from the cold but it was like no cold air, it was radiating from the dash. I felt the dash around my legs and it was ice cold so was the steering column, back of the steering wheel, top of the dash and my feet were burning… Pass side was normal nice and toasty…

    Took it in and was giving the run around… nothing wrong HEAD MECHANIC could not verify the complaint… So out the door they pushed me. Never got a “lets keep it over night so we can road test it when it’s cold out” nope just “it’s the way ford designed it and we can’t fix the design”. I told the chump at the service department that I was an X ASE certified technician and me telling him what was wrong was all the verification he needed. Please fix my new car… Sorry have a nice day …..

    So now I have to verify the complaint myself so I am going to video tape the temp reading of the dash while driving in cold weather. I have one of those point and shot thermometers, it records the temperature of any surface you point it at. I already did the vents… with the heater on High and full hot I get 134 degrees at the foot vent and 72 out of the side window vents with it being 35 degrees out… I would think they would be the same or close to it…

    Anyways next time I go back to the dealer I will have done my homework…

    By the way for anyone reading this I bought my 2007 explorer at a little place in Concord NH right at the end of RT 89…
  • Just got back from the store... 35degrees out, after running it for a while I took my thermometer and checked the very top of the dash..On the pass side far right it was 90 degrees and just a few inches over the top of the glove box it was 60 degrees. My left leg was 90 and my right leg was 72 … pass side under the dash was 114 and on the drivers side it was 72…

    Plus you can feel a cold draft coming from the steering column where the release is for the tilt.

    That’s normal I guess….

    It really burns my [non-permissible content removed] is when they don’t take the time to diagnose the problem, that’s the one thing I was well-known for when I worked for Exxon as a tech… verify the complaint… people just don’t make this [non-permissible content removed] up… drive it …drive it everywhere you go until you can verify the complaint… I know when I worked at Subaru warranty would only pay ½ hour for diagnostic time and then what ever they paid for that particular part to be replaced… so I’m sure they drove it around the block and said “it’s fine nothing wrong with it”

    I asked the service writer if they pulled the dash apart to check the actuators or moving doors, he said they can’t verify the complaint so they can’t rip and tear… because someone has to do it for nothing… that’s the biggest problem, it might take 4 hour to find it but they only get .5 hour pay for it… so they take the .5 and tell you your basically crazy and there is nothing wrong…
  • My 1997 Explorer has developed a problem that you can’t blend the temperature. I live in Montana and for the past several months having the temperature cooler has not been an issue, and I didn’t notice that when I turned the dial it was not cooler. I have been advised that it could be heater plenum and that having it repaired by the dealer will be very costly. They also thought that it could be the blend door that is stuck. Is there anything that I can do to find out the problem myself? How much work is involved? Any suggestions would be great!

    Ok here’s the whole story…….

    I bought the 07 knowing it needed a good cleaning, the sales manager that was driving it spilled a beer in it or it belonged to a drunk… who knows. Anyways I took it to the dealer for a recon and to check this cold dash problem I have. I told the service writer what was going on and that I was an X ASE tech and that I had an idea what was going on… I told him up straight “don’t call me and tell me there is nothing wrong with it” but he did anyways!!!

    Went to pick it up that night and went to the sales managers office told him we had a problem and I was not liking it at all! He tried to smooth it over by using the fresh air/recycle option but I quickly took over the conversation and straitened him out. It got to a point where he offered to let me fix it and he would pay me back lol Not….

    Anyways I got home with it and when I went to get my launch bucket out of the back…(oh ya when I got it back from the dealer both drivers’ side doors were open…and this is why)… and when I closed the rear door there it was staring me in the face. A nice little ding, looks like it was made with a spring loaded center punch right on top of the rear door…

    WTF… I could not believe it. I thought about it for a while and decided not to *censored* about it because I was already the big *censored* down there and I know accidents happen but they could have told me… I brought to the shop with me the next day to install some mud gauds and give it a bath. Got the guards on and had to call the sales man to see if I left something in the truck they let me use. I told him about the ding and that I was more upset about them not telling me about it than someone making a mistake. He got upset and said he was going to talk to them about it but I ensured him that **** happens and not to worry about it I wasn’t.

    I hung up with him and started washing it…
    Got all the way around it when I came to the pass side fender… there they were two more dings…WTF but these they tried to hide with some lighter color blue paint… I could not believe it…. I could go on forever, just use your imagination…
    So I load up the video camera and off I go to the dealer… I counted to 100 before I went in… I walked up to the nice little (not) receptionist and said to her… “Hello I have a major complaint who would I talk too” Hold on please… I excused myself and went to the bathroom so I could start the camera… no vid but I got the conversation…
    Got to the General Manager told him what was going on, who I was and what I wanted… Bla Bla Bla
    I got to talk with thier head technician, he seemed to be ok..... it was going to be 19 degrees the next day so I left it with them to have in the morning (something I mentioned to the service writer the first time)… I called today and they said they confirmed my complaint and had a regional technician on his way to look at it… Haven’t got to the dings just yet… he had the recon guy retouch it up thinking that was going to be good enough. He never let me finish my answer when he asked me if it would be ok to just tough up those spots with the right color. Not…. I’ll keep you all posted….


    Well.... They confirmed my complaint... but they said they drove another 07 and it too blew cold air on the driver’s legs... normal!! Sorry come get your truck... and all they did was touch up the paint, I told them that was unacceptable and they needed to fix the dents...

    ... So ford designed the 2007 explorer that way...I think not.

    Any ideas what I should do...??

    I'm at the point where I am going to let the finance company repo it... I don’t care anymore I’m getting tired of this, it has consumed my head to a point where I just don’t care… why should I be stuck with a truck that’s freezing cold in the winter and has three dents in it…

    Here’s the message that was on my phone when I got to work..

    The blend door is broken, lucky for you it stuck in the all heat position,but as you are finding out as it warms up you are screwed. You cannot just fix the blend door the entire heater box must be replaced. Depending on were you get the plenum, it will cost you around 160.00. If you are replacing this you might as well replace the heater core (aother 45 - 60 bucks.) The rest of the actuators that control various fuctions can be transferred from the old to the new plenum.

    I did it myself, but it is not a job to be taken lightly. This involves removal of the dash as well as air conditioning items located in the engine compartment, passenger side on the fire wall. A shop manual is very helpful if you have one. You don't have to remove the dash from the car, just far enough away from the fire wall to slide the box out from under the dash.

    There are other "temporary" fixes. But if you plan to keep the vehicle its the only way to go.

    To see if it is a blend door issue, open up the gove box and lower it to expose the top of the heater box. You will see the motor that operates the blend door. Unplug and remove. Now take a mirror and look at the hole were the blend door motor goes into the box. It should look just like the part that fits down into it. If not, it has broken and entire box must be replaced.

    If you want to do it yourself and need some extra info let me know...

    PLEASE HELP. I have a 2003 explorer with identical problem I looked and felt under dash for the suggestion in post 84 but no luck. The only thing I feel that moves is the opening to the adjuster to decide ac,defrost etc.. What am I missing?? Please email at
  • morinsfmorinsf Posts: 1
    Tried your fix and it does work. I do think that this is temporary as soon as I switch back to AC my problem re-appears. I do think this is a blend door issue. You can manualy fix this each time but this can be a pain in the neck, Thanks for the info.
  • I have a 2003 Ford Explorer and was told that the it could be the entire heat box or just a small little part . . . but the dash has to be torn out to fix it. Do you have any schematics on how to tear it apart and put it back together? If so, email them to me at Thanks!
  • I don't have the same problem but I can verify that the Ford mechanics at the dealer ship are stupid. I had a whistling sound in my 2003 Explorer in cold weather when I accelerated. It was under warranty so I took it in about five different times and they couldn't "duplicate" the sound. I told them it happened every morning when I pulled out of my driveway so come over to my house and then drive it. It was all set up (and I only live about 1/2 mile away) and then they called at the last minute to just have me bring it in. Of course, it made the noise on my way there but not when the guy got in and drove it 10 miles. I finally took it to another dealership and it took them a full week to even figure it out. It was the alternator so they replaced it and now it's doing it again and I don't have a warranty!
  • I have a 99 explorer that had the broken blend door problem. No help from Ford on the issue! I found a kit on ebay called Heatertreater. It was easy to install, and saved me a ton! This guy is a genius. :)

    I have the electronic climate control in my "96 eddie bauer. The system's air is going through the defrost vent (both heat and ac). No matter how I try to redirect the air it seems stuck in this position. Is this the blend door or something else?
  • I have a 2002 Ford Explorer and am having a probelm with the AC I recently changed out the compressor and and all three blend door actuator (motors) thats for rear and front ac and now my vents are blowing hot air on the driver side and cold on the passenger side. I dont know what else could be the reason for this. Can someone help me?
  • i have this explorer,with climate control.a/c is charged but it is blowing not very cold.i cannot find the the blend door motor.can anybody help me out?

    thanks steve ;)

    I have the EXACT same problem with 2002 Explorer. I have the dual control but I never use it.

    I called Ford and they told me to bring it in when it is acting up but they did not offer any idea as to what the problem is.

    Did you ever get an answer?

    The ac makes noise in the max ac position and on speed 3 and 4 sounds like leafs fluttering in the dash. Replace ac motor and still hear the noise. It quit for 2 days and has started back again. Any help would be appreciated
  • jstone3jstone3 Posts: 2
    Not yet did take the explorer to Ac place and got some oak leaves out and the noise quit but have since taken it apart and can't see anything else up there to make the noise and its back .

    I have a 2002 Explorer Ltd with dual zone climate control. The AC was blowing warm air. I recharged the system with 14 oz of refrigerant and can hear the compressor coming on and off every few seconds (did not hear compressor previously). The AC on the drivers side is now blowing cool air (not cold like when it was new) but the passengers side is blowing warm air. This must be related to the climate control, I am not sure if I should add another can of refrigerant or if something else is wrong.
  • Yes I did find out what the problem was, It was the evaporator core it was filled with dust particles it was easier to replace but they say you can pull it out and blow air with a compressor to clean it out from one side to the other.
  • Heres a thread I found that can be helpful when replacing the evaporator core lend+door
  • Maybe this can help on the blend door motor on my 2002 Ford Explorer XLT it was found on the driver side on mine. Here are some useful threads on where you can find it.

    Good Luck!
