#250 of 536 99 EXPLORER HEATER PROBLEMS
Dec 27, 2009 (12:33 pm)
WE HAVE A 99 EXPLORER AND ARE HAVING TROUBLE WITH THE HEATER. THE BLOWER WORKS FINE BUT THERE IS VERY LITTLE HEAT COMING OUT. IT JUST BARELY GETS WARM. WE PUT A NEW THERMOSTAT ON IT, BUT IT STILL WON'T GET HOT. THE TEMP GAUGE WON'T MOVE OFF OF "COLD" AND THE WATER IN THE RADIATOR DOESN'T GET VERY HOT EITHER. ONE MECHANIC TOLD US IT WAS A HEATER CORE?? ANOTHER ONE TOLD US IT'S A BAD MOTOR ON THE BLEND DOOR AND ANOTHER ONE TOLD US WE NEED ANOTHER THERMOSTAT. WE'VE BEEN TOLD THAT THE WHOLE DASH HAS TO BE REMOVED AND IT'S GOING TO BE EXPENSIVE TO FIND THE PROBLEM. DOES ANYONE HAVE AN IDEA?

The door is on the drivers side, it is a bit involved getting to there. Check out the videos on www.heatertreater.net. I wish I lived closer to Texas to have them fix it. Good Luck.

I can't believe that you guys had the same problem with no heat from the 2004 Explorer. My temp control was clicking loudly as well, and then one day lost all heat. Thanks to the guy that found that blend door lever. I just went out in 20 degree weather and found the lever and fixed it. I would have never found it, and I am a retired mechanic. Thanks for the tip, she's blowing mighty hot heat now.
#253 of 536 98 Ford Explorer Heater/Defrost Challenges
Jan 04, 2010 (8:21 am)
Good morning Folks! I have a 98 Ford Explorer which out of the blue has decided to direct all hot air through the Defrost Vent below the windshield. The Digital Push Buttons indicators on the dash control clearly respond as if the hot air is directed to the floor or the panel or mixed - HOWEVER ONLY THE DEFROST VENT has hot air flow. Feet get cold like this and nose gets dry LOL! I am a techie and it seems as though the the Blend Door actuator is working as warm or cold air (when AC is on) gets to the dash in defrost mode - it seems as if I may have a stuck Floor Panel Door [if there is one in this 98 Explorer (and where would it be so I don't have to take off the entire dash to locate it further diagnose) (its stuck closed routing all air to dash defrost vents). Is there a part I can go to to check if vaccuum to that door is avaialbale and the hoses are connected and do not leak or are broken -or is there a digital low voltage switch that activates that door that I need to locate and replace. Thanks! gary

In regards to your 98 Explorer that heat is only directed to the defrost outlets, I have a 2004 Explorer and recently had to work on the heater controls. On the 2004 you can access the vacuum control by dropping the glove box door down . You can easily see the vacuum control on the 2004. It is on the upper left. You can manually move the control on mine to change the flow from defrost to heat. It's worth a check to see if you can locate yours in that area. Of course the engine has to be running, in park and brake on. Hope this helps somehow.

I have a 03 explorer, when I turn the temp from cold to hot there was a clicking noise Then one day it would just blow cold air. We checked the heater core and it is hot. My boyfriend took the glove box out and found a lever making the clicking. Right now he has a shoestring tied to it and pulled for heat. Can someone please tell me what I need to fix this.

I can smell engine coolant when the heater is on and from reading your prior post I have an additional directional air flow issue(only comes out the defrost vent).
When I have the thermostat in cool, I smell nothing, but when I turn it to heat, cant see due to the windshield is fogged up. Any news good or bad would help. Is it safe to drive in cool mode, until I can get it fixed....and whats the fix.

danbo1, What you are describing is a typical heater core leaking. You might want to try a good grade of stop leak . You would add the stop leak to the radiator, going by the directions on the container. General Motor's parts departments have an excellent pellet type of stop leak that might well stop the leak until you may then want to have the heater core replaced. Some of the Ford models are very expensive to replace. Don. Retired mechanic.

Thanks to all for the tip on locating and fixing the lever for the heat control. It took me awhile to locate it but finally found it and heat is restored. Yea!!
