Ford Explorer Air Conditioner and Heater Problems

  • The clicking sound you hear is the A/C compressor clutch engaging. It clicks when it disengages also.. As long as it produces cold air and the noise isn't excessive, you should be okay. Worst case scenerio is the clutch freezing up and then it burns the fan belt off. Would't hurt sometime for an A/C specialist to just listen to it while parked outside. It engages and disengages more when you are not on the MAX AIR setting.

    Hey Clusterbuster,

    I was finally able to get home and check on your advice. Worked PERFECTLY!! Thanks so much. It literally took me less than a minute, from opening the door to turning the lever and now the a/c comes out of the dash rather than the defroster. Wow! And to think the dealer wanted $1000 to fix this. All that is wrong is that there is a plastic arm that is broken that connects the lever that changes the gate to the arm that sticks out of the vacuum canister. Hopefully I can find one online. I hate to go to the dealer and deal with those guys again. If you know of anywhere to get that part I'd appreicate it.

    Again thanks for your help. You da man!!! God Bless!!

    Hey Carly,

    Yeah I found out what my problem was. Go to post #293 and to Clusterbuster's reply to my original post. All it is is a plastic lever that connects the flapper arm to the vaccum canister, the plastic lever was broken. Lower your glovebox, look way to the left and up a little and you'll see it. Fairly easy to get to. Now I have to find out where to get that part. The dealer will be last, especially after they quoted me $1000 to fix it.

    Hope that helps and good luck!!

  • The vent on my 2004 Ford Explorer began knocking when we turned on the fan for the heater - only cold air would come out, but it was working fine with the A/C. Now it seems to not blow out air thru the vent for either - but feel air coming thru the glovebox.

    Any ideas and can I fix it myself?
  • What do you want to work, the heater or A/C ? Is the air coming out of the defroster vents at the bottom of the the windshield as well ?

    HELLO, I HAVE BEEN READING YOUR MESSAGES. I HAVE A 98 EXPLORER ALSO WITH THE SAME ISSUE. I CANNOT FIGURE THE THING OUT. I HAVE TAKEN IT TO 3 MECHANICS AND NO ONE CAN HELP. THIS IS SO CRAZY.

    If the actuator motor is not bad,then the door inside the blower box is broken,the outside air ,when moving,also is moving the door,therefore changing the temp.I have found this on many explorers.

  • My 1998 Explorer air conditioner only works on High. If i put it on low, it only blows warm air. How can I fix this?

    The ac/heater control is bad,it is the problem,and will have to be replaced to solve the problem
  • Wayne,
    I have the same issue in my 03 Explorer. Just like yours the plastic arm that controls the door is broken. Can you replace the arm or do you have to replace the door? If so what is the name of the door? any information you can give me would be deeply appreciated

    Thanks,
    Frank
  • Hello,

    I have the same problem that dobbsa posted on #230:

    "I have a 1998 Ford Explorer. The A/C works fine at idle up to moderate speeds. Once it is at highway speeds, then the A/C turns warm. When I slow down the A/C gets cold again."

    Would that also be the blend door issue?

    Any one have any ideas?

    Thanks.
  • HELLO, I HAVE TAKEN IT TO NUMEROUS MECHANICS, SHADE TREE AND TRUE A/C REPAIR SHOPS. EVERYONE SAYS MANY DIFFERENT THINGS. AFTER PAYING ABOUT TWO HUNDRED DOLLARS JUST FOR PEOPLE TO LOOK AT IT. I GOT IRRATATED AND STARTED GOING THRU IT MYSELF. I HAVE REPLACED SO FAR. ACCUMULATOR, A/C LINE, FILTER. NOW I AM WORKING ON REPLACING THE COMPRESSOR WITH ONE FROM THE JUNK YARD. I EVEN REPLACED THE CUT OUT SWITCH. NOW I HAVE ONLY HOT AIR ALL THE WAY AROUND. THIS IS CRAZY. I AM READY TO JUNK THIS THING IN FOR SURE.
  • cleavon2,

    I am going to try the blend door replacement kit from heatertreater in the next week or two. I'll let you know if replacing the blend door corrects this issue. Have you tried that yet?
  • I HAVE NOT TRIED THE BLEND DOOR REPLACEMENT

    I have a 2007 Explorer.

    The front A/C works, but there's no A/C in the rear vents. I read some of the other posts -- I couldn't tell if the exact issue was covered...if so...sorry for the duplicate. If not....thanks for your suggestions.
  • 2002 explorer, manual a/c. heat and a/c blows fine. switches from hot to cold fine, but will not change vents. checked the diaphram on the right side behind the glove box and the lever is not broken. i can move the lever in and out and it changes from top to bottom no problem. is it vacuum operated? and if so, where does it get the vacuum from. traced the lines into the engine compartment then lost it behind the engine. any help?
  • Yes it is vacuum operated. I would take the vacuum hose off the diaphram that you moved the lever on, and with the engine running, parking brake on etc, see if there is a vacuum at the end of the hose when moving the dash control from defrost to heat etc. Chances are it would be a bad contol unit on the dash, as I doubt there is a problem with the vacuum supply from the engine. If there is vacuum at the hose end when moving the control, then it's likely to be a bad diaphram. Hope this helps some. Let me know. Clusterbuster.
  • We also have this problem on our 2002 Explorer. I'm looking to see if anyone has any pictures they can post of this assembly (taken from the glove box access point) and point out where the various usual suspects are to check. The only reason I ask is that our truck's previous owners I think have already done some creative repair and I'm not sure what is supposed to be there and what is not...
  • Have a Ford Explorer 1996, A/C works good in max position, when I switch to A/C
    position only hot air comes out -- also only hot air comes out in vent position. Temp control will not change from cold to hot air.
    Have read about a blend door behind glove box. All fuses are ok. Is this my
    problem?
    thanks :(
  • Went out to check blend door--can see door open and close when going from Max AC to vent position--but still only hot air coming out of all vents.. Must be problem
    somehere else! AC and all vents are hot air--only Max A/C is cold.
  • wwestwwest Posts: 10,706
    An automatic HVAC has a cabin temperature sensor and if it's open you only get cooling in the MAX cooling position.
  • I drove the car home with front control dash unhooked---hooked it back up at hme--now have A/C and cool air working ok again---am afraid to turn temp dial to heat as before problem started--may have problem this winter if need heat!
    Problem was all normal until I turned temp dial to heat one cool morning---then went back to A/C at pm---then only heat came out.! The Ford fix book talks about a blend door--not sure whrere it is.

    I was curious if you've tried the blend door replacement kit from heatertreater yet and if it worked? Was it easy to install?
  • No, I haven't done the replacement. My guess is that it would be fairly difficult. I drop the glove box door and move the blend door arm manually when it gets cold enough to need heat. Some people tie a string on the lever and pull it from beneath the dash when needing heat. I might just do that until I get rid of my 04 in a year or so. Good luck.

    I will be replacing the blend door over labor day weekend. I'll report back next week with the results. I am pretty certain that this will resolve the issue. To gain more insight on the procedure to replace the blend door, check out heatertreater.net and then select '96-02 Ford Explorer. They have two 10 minute videos detailing the blend door replacement. Very informative.
  • hthornley,

    See my last post. I am fairly confident that your issue (mine as well) is the blend door defect.
  • Hey....I have a 1996 Ford Explorer and the rear A/C blows fine but the front fan won't come on. It just clicks. Could it just be the fan?
  • The temperature control arm is not changing the temperature of the air that comes out of any of the vents. Is this mechanically controlled or electric?
