2004 Ford Expedition rear floor cool/heat

I am having a problem with my Expedition, when I press the button for the heat to blow through the back floor it doesn't work. The heat will only blow from the roof.

I turned the knob for rear control and pressed the button from the back, it still doesn't work.

So, the floor vents are not working, just only the roof air vents.

2004 Ford Expedition rear floor cool/heat - 03f81ff.gif
Item Part Number Description 1 — Air inlet door 2 — Temperature blend door 3 — Headliner airflow 4 — Auxiliary mode door 5 — Floor airflow 6 18476 Heater core 7 19860 Evaporator core 8 19805 Blower motor
The auxiliary A/C and heating system has the following features:

  • The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
  • The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
  • Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
  • The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
  • Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
  • Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.
---------------------------------------
I would say the auxiliary mode door (#4) electric motor is not wokring.

Ford Expedition 1999, Climate control system, A/C blowing Hot air.


I have had my head scratched trying to figure out why my truck kept blowing out extreamly hot air and no a/c. I've done the stuff of taking apart the dash, which seems to have a billion screws you have to remove, to get to the blend door and fixed that part. Only to find I still didn't have cold air. So, I kept researching the internet and reading my Haynes book. This is when I did the smack on the forehead like "I could have had a V8" drink. OK, now for the moment....

If you have it equiped on your Ford, there is a trick to check your climate control OBD-ll system for the inside of the truck. The OBD-ll system (On Board Diagnosis). You can see if you have a problem with the area of the climate control system for the inside of your truck. You have one for the engine as well, but that is used for the pros. and is for other areas to your truck.
1. Turn on your truck.
2. Turn your heat on to desired temp. for heat. Now, do step 3.
3. Turn off your heater and A/C.
4. Press both the Floor and Off buttons together, WITHIN two seconds, release the Floor and Off button and press the Automatic button and release. Give it about 30 seconds to a minute. You should see a little single led dance on the screen where you would normally see the temp.
5. Once that time is up, you should have a number code to located your problem for the cab. If you only see it all lit up with three 888's. Then you might not have a problem. However, you just did a troubleshoot on the system and you should have normal heat and A/C coming out.

To exit:
6. To save the code press the Defrost button, then the display will turn off. To erase the information press the Blue button (A/C) then it will turn off the test display.

Note: Once you turn your heat or A/C back on you will see it is set to 75 degrees. That just means you did it correctly.
Good Luck. I hope this helps. If it does please leave me feedback.

Hi,I have a 2005 denali yukon when u press the directional button to blow air out of top vent it still has air blowing on your feet any solutions or what to look for n how to repair it thanks john


First try this reset procedure .Set A/C panel to what ever setting you want just as long as the system is set to be on. Dissconnect the negitive battery terminal for 20 minutes .... hook the battery back up ... start the truck back up and do not touch any buttons ... the A/C should start going threw it test switching from defrost to vent to floor .This may take 5 minutes or so when its done shut the truck off then start it back up and move your setting to try out the system .if it all works right the module just lost its memory and you are all done if it doesn't then you have a bad Upper vent accuator that needs to be replaced

2004 Expedition - rear heat blows cold air only. I'm told that the blender or damper door is likely broken. Does anyone have a diagram of the rear heating system I can follow to replace this part?


The Expedition uses the same HVAC system as the Ford F150 pickup truck. The Expedition is a little tricky though because you have to remove the center console and floor heat distribution vent to access the actuator motor. Once you remove the motor, you can examine the blend door axle for cracks or breakage. This is a common fail mode on the Expedition.

HeaterTreater is the world's leading company for aftermarket blend door fixes and has a product for the Expedition. Additional diagnostic information and pictures are available on the Ford Expedition HeaterTreater Ebay listing or the web site at www.heatertreater.net. There is an inexpensive effective fix available that replaces the cheap plastic door with steel that will outlast the vehicle.

your controls have problems. the heat is there it is just not getting out because your control lines are not setting the vent controls into the proper positions. i had a chev van that lost some of the foam in side there and it blocked the whole front off. i had to rip it all apart to get at it
