Ford Expedition Climate Control Problems

245

Comments

  • I have recently purchased a used 2008 Ford Expdition Eddie Bauer from a dealer with 12K on it. My problem is that the heated seat work OK, but do not get as warm as my old 2001 Chevy Tahoe seats. It seems that the back of the seat is warmer than the base of the seat. I have not talked to the dealer yet, but will on my first oil change coming up soon. Anybody else had experience with not warm enough on the heated seats?

    I was told the blower motor heater module is what changes the blower motor speed and when it goes bad, the blower motor only operates on the high speed switch setting. Would anyone be able to confirm this and if correct, walk me through where this resistor module is exactly located. Thanks in advance.
  • I just bought a 1999 Eddie Bauer Expedition and I see that my problem is common. I will get "warm" heat out of the front floor and cold from the defrosters at the same time..or cold from both. This has the auto Climate Control and I can change temps from "warm" to AC and it will change and blow cold but it wil not heat.. drove it 40 miles one way and NO HEAT!! Rear controls work awesome!! I keep seeing people talking about this but have not seen any solutions short of taking it your dealer and get raped! :mad:
  • One morning it was 50 degrees and I set my heater control to hot. The next day I tried to set it for 'cool' outside air and found it remained hot. Since then, it has stayed hot no matter where I dial my Hot/Cold selector to. I don't use my air conditioning much because I keep it on the PANEL selection when I want to save gas. Now, I can't even get my air conditioning to cool my 1999 Expedition interior down. I get hot air no matter what. My buddy says that the 'electric switcher' that controls the heater door may be faulty(causing the heater door to remain open) or I may have a broken shaft that the motor turns. When I turn the hot/cold dial, I hear nothing. No clicking, nothing. I try my dash panel selector and it changes to the appropriate venting, floor, windshield, etc. But stuck on HOT for some reason. Could my relay in my fuse block be bad? Please help me to find the fault. Thanks. Scott
  • Sounds like a broken blend door. that's a big job - the dash has to come out. There is an aftermarket kit for this that you need to cut the back of the glove box out for - i think it is called Heater Treater or something like that.

    The other one is Blen Dor. Both outfits hang out on the forums here trying to, er, market their stuff without running afoul of our no-soliciting or self-promotion rules. You can find both on eBay.

  • My '06 Exp. A/C blower ventcontrol (?) just stopped working this morning. A/C will turn turn on and off but air only blows thru top vents. When I turn control knob to other vents nothing changes. Any ideas out there? Any and all help is greatly appreciated.
  • On my way home this morning, I was turning a corner and hit a small bump and hear a noise under my dash like something rolling or a rattle. I became curious and thought.... Could it be????? I turned my position(air flow) dial from off to panel.... And I had fresh cold outside air flowing in again!!!!I looked at my water temp guage and it was fully warmed up. I guess it was a stuck door as I have heard ohers talk about. Could it be? I won't turn my temp control to heat again, for fear the door will stick again until I have time to fix what ever caused it to stick. Now I can use my air conditioning again when I need, because it won't be fighting with the heater. If anyone has encountered such a thing as I have, please let me know what I need to do to fix this. I wonder if the door gasket is sagging and interfering with the door.Maybe it isn't the gasket because NO heat is seeping through at all. I guess I can't lube anything near the door because it is inside the 'box' ? Thanks for your responces so far. If I need heat, I will use the rear passenger heat...... It works fine( temperature control). Thanks. Scott ;)
  • If you have the same system as my 99..... It could be the vacumn diaphram or a cracked or broken hose?? Mine sounds like a vacumn system because when I switch my dash blower locations, I hear a short hiss, followed by the doors 'blend doors' closing/opening. I have known this vacumn device to be located on the passenger side behind the kick plate.as it is on other vehicles. I would assume that to be the location. I really need to buy a Chiltons manual though . Hopefully you have an easy fix. Check the fuses????? Thanks. Scott :shades:
  • I did check fuses first thing, I will try and listen for hissing sounds. Are the wires behind the contol knob actually wires or are they vacuum hoses? When you say kick plate, do mean left or right side of passenger side?
    Thanks for the advice, Vic.
  • Right side of passenger side. And they may be vacumn tubes instead of wires behind that switch. I am not sure. That is just a guess and the tubes can be color coded (AND LOOK LIKE WIRES). so the assembler knows where to attach them to, under the dash. This is just a guess. I am sure that mine is vacumn activated by the sounds I hear when I switch dash vents. Call a Ford dealership and ask if the vents are vacumn operated ....... first, before taking my word for it. It is just a guess and from past experiences with other vehicles.. Thanks and good luck. Scott
  • I JUST FIXED MINE , THE PROBLEM IS UNDER THE BIG BLACK PLASTIC COVER ON TOP OF MOTOER , ON RIGHT SIDE( LOOKING AT ENGINE) THERE ARE TWO BOLTS TAKE THEM OFF AND LIFT COVER OFF, MAYBE A LITTLE TIGHT DUE TO THE TWO POP ON CONNECTIONS ON LEFT OF COVER, REMOVE COVER AND ON LEFT SIDE RIGHT WHERE COVER SETS IS WHAT I CALL HEATER VALVE A ROUND TUBE LIKE CANISTER ABOUT 4INCHES LONG AND 2 INCH ROUND, THERE SHOULD BE A 1/8 INCH HOSE HOOKED TO IT BOTH SIDES AND THE ONE IN FRONT COMES OFF DUE TO VIBRATION OR MOVING THAT COVER IF YOUR HOSES ARE ON THEN THE HOSE IS DRY POTTED AND THERES A LEAK ON THAT LINE. MINE WAS DRY POTTED AND WAS JUST ALMOST OFF SUCKING AIR. DEALER JUST WANTS YOU TO BRING IT TO THEM SO THEY CAN CHARGE YOU..I HAVE A LITTLE VIDEO IF YOU NEED IT JUST EMAIL ME,... JOHND7854@AOL.COM
  • GOOD! I knew there was one, I just didn't know where.:D. OK, folks, don't remove them kick boards.

    I have a 2004 ford expedition eb 5.4. last night i noticed that the driver side climate control seat was not working even though the thumb wheel light was illuminated. The passenger side was working fine.
    I tested the switch by putting it in my buddy's expedition and it worked fine, so i'm thinking it's something a little more serious. Please Help :confuse: :P

    Hey everyone. I have a 2004 expedition EB 5,4. Having a problem with the reverse sensing system. When i put the truck in reverse the messenging center is telling me to check the system and i'm not geting any warning tones. Any idea's ?

    Thanks :blush:
  • There is a relay on the firewall that may fix this problem. My blower would only work on high and I had that replaced. It corrected the problem.

    I have looked all thru this forum for answers to heating issues with Expeditions but all I see are questions and no answers. Is their anyone that actually monitors these questions to give educated answers (help) to the people asking teh questions. I personally am not finding this fourm very helpful at all.

  • would like to get a copy of the video if you don't mind. thanks
  • I have a 2000 Expedition XLT with a 4.6 and my air blows on every mode but the heat doesnt get hot at all. One hose gets hot, but the other one stays cold. I've changed the thermostat, flushed the entire cooling system but still no heat. Any suggestions ??
  • i have a 1999 Exp. 5.4L .. i have replace all the heating parts in this SUV , the only thing i haven't replaced is the heater hoses ... the blender door is working perfectly i have taken the dash totally apart and watched it work .. the problem is the rear heat gets to 73 degrees , front heat only gets to 69 degrees ... the dealership tells me after $500+ spent to the dealer they have no idea whats going in ... some kind of pro service department from ford ... (they all have a PHD in stupidity if you ask me) any other ideas anyone ???
  • I'd suggest checking the vacuum lines that route around the battery area (at least they do on a '03, I don't recall where they were on my '99). They are prone to breaking down and develop small cracks that are barely detectable, but have a huge impact on how the system performs.
  • I and the ford dealer both have already done that .. I have traced them down more than 3 times now , no leaks .. The dealer claims theres no reason for this to be happening considering the temp. differences between the front and rear differing so much .. Any other ideas will be greatly appreciated , I have exhausted all i or and the dealership can guess , assume , or read in the books .. The service tech told me today just shoot it and buy another one .. :mad: :confuse:
  • does your heater hoses under the hood get so hot that you can't hold them? If not and your heater core is clean and not stopped up you might have and intake gasket blowed, I run in to this problem on mine. There also could be a crack in the intake right where the heater hose hooks on the manifold.
  • yes engine is at correct running temp. well the shops and service department at dealership all say they are at a loss ...
  • I have exactly the same problem on my 2000 Expedition- only 'slightly warm' heat.
    I had the heater core replaced 1 year ago. Just recently, the system was flushed and the thermostat was replaced. Engine temp looks OK, per gauge. Problem persists. Switching from hot to cold does change the air temp so I "think" the blend door is working.

    Any new developments or ideas?
  • I have 99' and replaced the heater core 1yr ago and just dropped a new engine in the last week. I have heat in the mid seats and the far back(rear) but only cold coming out of the console does anydoby know why this would happen? Also I was told that there are 2 heater cores one for the front ane one for the back. Is this true?
  • I have the same problem with my 98 XLT 4.6L
    The other problem I'm having is that once the temp gets into operating range, it will all of the sudden shoot to hot and the engine will lose power. If you are at cruising speeds of +50, it will click back down after about 20 seconds, but if you are city driving, it won't click off until shut the truck down and wait 10 minutes.

    I just had the freeze plug changed out and replaced the overflow reservoir - all to no help.
