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.

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.

My 2004 expedition When you put it on cool vent


This sounds like a blend door or actuator problem. Testing this is a pain and the repair may envolve removing the dash board and center console. I strongly recommend taking the vehicle to a repair shop. This one is beyond the DIYer especially if your pressed for time.

2003 Ford Expedition blowing hot air only. Is it a leak or major problem. Also there is a clicking noise in the back rear when you put the ac on


Sounds like your rear actuator for heat and cool is stuck in one position this normally happens when the plastic gears shear down, you will need to change out the actuator. You have two on the rear passenger side, one is for teh hot and cold and the other is for teh upper and lower air

Front heat works, but rear blows cold air only


With your front heat working the most likely cause for the rear heat not to work is that there is an obstruction in the line that is preventing the warm coolant to get to the rear heater core or the rear heater core itself is plugged and not circulating. Another possible cause could be low coolant level where the system has enough coolant to provide the front system with enought warm coolant but not the rear system. Hope this helps

99 Expedition blows cold in front but not in rear cabin. Heater will work in rear, but no A/C. Front A/C and heat is normal.


somewhere in the cabin there is a panel, behind it there will be a small vacuum valve that opens duct heat/cool for the back. I had it go bad in a windstar and stuck on heat, too lazy to replace so i'd pull panel and manually move it once or twice a year

Front vents do not work, a/c is blowing through the defrost and floor vents ur 2004 Ford Expedition Problem


I had the same problem and found that the vacuum tube located behind the battery was cut. The tube is about the size of an ink tube inside a ball point pen. The size is 5/32" and can be purchased at most auto parts stores. A quick splice and you will be back to cooling.
