Ford Expedition Climate Control Problems

kdxfankdxfan Posts: 1
I replaced the battery in our 03 expi and now the A/C controller wont turn on. i checked the fuses under the kick panel inside the truck....any ideal what it could be?


  • I bought a 98 exp xlt 4.6L early in 06'. I have the rear ac/heat option and now that the cold season has hit, I have not been able to get my rear heat to work. The blower works just fine and so do the blend doors. One of the hoses to/from the heater core is hot, the other isn't. The heater core also seems to be ok, unless a possible blockage....? Any one that has any ideas on troubleshooting this, please let me know. Thanks.
    I recently took replaced the front heater core myself. I was getting luke warm air, but not hot. Then the heater core blew. After talking to a Ford repair man, he informed me its very common for the blend door to go out in Expeditions. I need to fix this.
  • I have a 2000 Ford Expedition Eddie Bauer I am getting no heat at all front or back cleaned out heater core changed water pump and thermostat had sytem flushed don't know what to do next
  • I have a similar issue. I have a 99 Expedition Eddie Bauer. The fan the controls the A/C and heat does not work. The temperature is controllable, but that's it. I don't see any burnt fuses.

    At one time, I was trying to swap a turn signal relay and the fan conrol stopped working. The dealer says the problem is the dashboard climate contol unit.

    Have you found the issue? Is there a loose connection somewhere?
  • I brought my Expedition to the dealership for another issue and asked them to take a look at the heater; They indicated the climate control head unit (in the dashboard) was faulty. More specifically, the switch that controls the fan is no good. I thought it was very strange since I'd never touched the unit or any related parts. I went ahead and bought a used replacement off Ebay for $40 and installed it. IT WORKED! I didn't think it would...but it did.
  • How do you fix the air conditioner on a 2002 Ford Expedition that switches from the panel to the defrost vents when the engine is under a load?

    Every time the engine is over about 2,000 rpm's the a'c switches from panel to the Defrost vents.
    any idea why? any tips would be greatly appreciated


  • i have a 1999 Expedtion and it suggest that I replace the Cabin filter, where is that located? If anyone can tell me

    Just yesterday i went to turn on the rear A/C for my kids and the air wasn't blowing out of the overhead vents. We could hear the air blowing but it was blowing in the third row seat floor vent. Any ideas? :confuse:
  • Hello, I have a 1998 Expedition with the 4.6l motor. There is some heat coming out of both sets of vents, but it doesn't get 'hot' at all. The temperature regulator knob seems to work. What might be the problem? Thank you for your help.

    This is a 4 dollar part that when it fails it does so in a way to keep the car from overheating and the cabin heater core from ever getting hot enough to give you "heat"

    If the air from the vents gets colder at highway speeds, then this is the likely culprate.

  • Thank you so much for your help, I will get the part soon, and let you know if this works!
  • Hello:

    I have a very similar problem as to these other postings I have read,I have a 1998 ford expedition xlt with a 4.6 ltr engine,any ways
    I just realized that my heat is not blowing hot air it is blowing luke warm to cold air & I am freezing in the a.m.!! even when I start the truck in the am I let it run for like 20 min & still no heat!! I changed the thermostat and did a radiator flush with top of the line anti freeze,on the high way it does get worm thats about it,but when i slow down it gets cold again. I am starting to think the heater core is on its way out!!

    does anybody have any idea why this is happening? is my heater core on the way out??
    is it easy to change?what else can it be?

    Thank You

    I would like to fix asap as I do have kids to bring to school in the am!
  • I have the same problem as my post reads down below yours from milliard,have you gotten any good ideas of what it might be??
  • Hi,
    I have a 2004 Expedition. My air only blows up by the window, and not out the vents like it is supposed to. The switch that controls where the air will blow doesn't seem to be working properly, because I only get air flow at the window ( like defrost) and off. Do I need to replace this switch or is it some vacuum line or something that is not allowing the air to transfer to the proper location that I select?
  • I have a 05 Expedition EB with heated and cooled seats and had the same problem. I called the dealer and they said it was the control unit, but I did'nt think so because when I tried to switch it to vents I can hear a clicking noise like it's trying to move. So I started pulling the center console out and looking at the vacuum lines that control were th air gets switched. there is a manifold that has 6 tubes in it. A black,white,red,orange,blue, and yellow. The black and white are the two that come from the vacuum side so I took a air compressor and blew into all the tube and then it started working again. So I think the small tube must have had some junk in the line. I took some pictures of the area so if would like to receive them just email me at and I will send them to you.
  • got 05 have problem with gas fumes when using defrost been to dealer 4 times they can't found it
  • Folks I am brand new to this forum and maybe I over looked the fix or maybe I didnt, anyways I have no heat in the front of my 98 ford expedition but plenty in the rear heater system. I understand that there is a blend door actuator that controls the Max cold-maxheat, but where is the damn thing and what do you do to fix this reoccuring problem that the Ford recall team seems to ignore?

    seams to me we have the same problems with these ford expeditions, I have a 2003 xlt ,overhead rear heat works great, dash heat stay`s cold no matter where you set the temp control knob. any suggestions, my local ford dealer charged 77 dollars just to tell me it needs a blend door controler, and it will cost me 1300 dollars to fix , forget that i`ll trade it off first, anyone know what i can do to fix it myself, ? :mad:
  • Sounds like I am not the first one with this problem. I disconnected the hoses to the front heater core and ran water through it. The core is clear. I then reconnected the hoses. The inlet hose becomes hot. However, the outlet hose never warms up. Can someone help?
  • I have a very similar problem. My front heater core is clear--we disconnected the hoses and ran water through it. When the engine is at normal operating temp, the inlet hose to the core becomes hot ---the outlet hose remains cool. Any suggestions?
