Ford F-Series Climate Control



  • 2004 F250 never got heat or ac to lower vents everything defaults to the defrost vents and no one has fixed it yet? anyone have a solution?
  • I own a f-350 2004 6.0 It just started not putting out heat even if the temp control is on high. It does this at idle. But if you drive down the freeway it will start putting out hot air and then it changes to warm air without touching the Temp switch. If you stop and idle the air turns cold. It is in the ford shop but after a day of testing they don't know what's causing it. They did say it might be the head gasket but they are not sure.

    Sometimes I have heat and sometimes I do not. Had anti-freeze, thermostat replace. Did not hear hissing sound when changing to floor, froster, ect. Had that replaced too. Not sure what the issue is now. Anyone have the same issue or anything close to that.
  • Did you ever determine what the problem was.
    I have the exact same issue. Started yesterday. 2004 F250 6.0.

    I had the climate control panel replaced in my truck and that seemed to help. It takes a while for heat to come out after about 30 minutes of driving now. The person working on my truck thinks it might be a motor issue under the dash that controls a panel the directs the heat( open / closes a door). He has to take the dash out so replace the heater core while he's there. It seems to me a lot of the Ford trucks have this issue, even the newer models.
  • I checked the level of coolant in my truck and nothing was there. I stopped off at the local NAPA Autoparts and poured in an entire container of antizreeeze. Still didn't register. continued to fill the reservour up with water to the lines. Started the truck and instantly the heater started working again.
    Feel pretty stupid for something as easy as coolant level. I am going to watch it though, because it's going somewhere.
  • I have a f-250 lariot. the blower motor on the a/c / heater only works on high. does anyone know what could possibly cause this?
  • is there any way to change the celicus to farenheight on the display. nothing in the manual. been searching the web so far nothing. I have an f150 lariat 2003

    Anyway, I'll assume that you bought the truck used and don't have a manual.

    You can download your manual here:

    If you were to read the manual, on page 41, you would learn that if you press and hold the MAX A/C button and the Defrost button together for 1 second, it will switch you from F to C :)

    Good Luck,

  • I have a 1995 f-150 with a 4.9- 6 cyl.
    we have replaced the thermostate (with a 195(recomended),This we tested and it works.We also maded sure the water flow thu the heater core-is flowing, (we hooked a water hose to each heater line and water flowed,good),and the flapper controll under the dash is working.The 2 hearter water lines are very hot after engine runs a while.
    the heater will not get warm.
    you got any ideas we can try?
  • Check the blower motor speed control modual/relay/resister. Will be located in engine compartment attached to either the A/C coil box or the heater core box. If you have already solved the problem please let me know. I have a friend with the same problem in hers,She is not willing to spend the $90 the part costs unless it will fix the problem.

    I have the same truck and having the same problem. Have you figured out what the problem was and how to fix?

    04' F250 has 54,000 miles. I first checked the colant level. It was low. (Added two gallons of 50/50 coolant in January. Just two weeks ago I check the level again and it was two gallons low.
    Took it into the Dealer. System would not hold vacuum.
    They replaced EGR Cooler, Oil Cooler, T-stat, misc. Factory Warranty. so far so good.
  • The problem is usually not the heater core, but the blend door. The F150(and Expedition/Navigator which use the same plenum box) have a common problem with the plastic axle breaking. The OEM fix requires complete removal of the dash, including removal of the steering column and evacuation and disconnection of the AC refrigerant system. It is a time consuming and expensive repair.

    Check out this web site for diagnostic information and options to repair the system at costs significantly below what the dealer will charge. These guys are the experts on blend door issues on Ford, Chevrolet, and Chrysler and have a bullet proof solution to the problem. link title
  • I am having major problems with the climate control in my truck. If its in the mid to upper 70's and I want AC I have to set the temp to 60. If I set it to 65 it blows warm air. Of course at 60 it get freezing in the cab. The same goes for heating. If I set the temp to 65 it blows hot air. The interior gets very uncomfortable. So I put to 60 and the cab gets cold. I have to keep alternating between 60 and 65. There are no in between settings. Is anyone else experiencing this problem.

    I took my truck in for service today with the same problem. Was told that Ford issued a service bulletin to all dealers indicating that Ford engineers were researching this problem and something will be out in late November. The local dealership advised me to wait. :sick:

    i have a 01 f350 diesel and have an issue with not being able to select either floor or vents etc defaulted to defrost, i have checked the fuse #24 for the blender door and its ok, just wondering if anyone else had any ideas what i should be looking for I don't have a shop manual for the truck. also doesn't seem to do anything when placed in ac position.

    thanks in advance Warren K :(
  • I have a 2007 F150 and I am having a problem with the climate control. It won't control the temp. I took it to a dealer and he tells me that the part I need is on back order and other dealers are wanting the same part. Is this a ford problem that others are experiencing?
  • I had a leak in my heater core. After putting in some Stop Leak the steaming up of the windows stopped but I still have the odor of Anti Freeze in the cab. I had the same problem with the odor a couple years ago in the summer and took the truck in. After 24 hours with 30 lbs of pressure on the system they told me there was no leak. So I had them change the coolant anyway and here I am. Even when the cab was steaming up I never seemed to lose any coolant yet the odor remains.

    Has anyone had a similar experience? It is a 1997 F-150 Lariat with 4.6 8Cyl.
