Rear A/C for 2005 Ford Expedition

The rear A/C on my 2005 Ford Expedition works but will only blow out the floor vent. I cannot get the air to blow out the roof vents. Anyone know how to solve this problem?

I had same problem. What I did was a temporary fix that needs to be repeated once in a while. Here goes. Remove the rear cup holder that is above the rear vent on the passenger side of the vehicle. Take a long Flat Head Screwdriver and try to rotate the white plastic gear clockwise by pushing it on the left side of one of the teeth. You will feel it give and should feel air coming from roof vents instead of bottom vent. It is pretty easy to do but may have to be repeated off and on.

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.

How to fix rear heater not blowing out vents can hear rear blower motor blowing also rear floor is blowing cold air


The rear heater will use vacuum or an electric motor to control a blend door to direct the airflow. This may be a big job to access this blend door actuator for testing as the interior paneling will have to be removed. If there is no heat available to the rear, check the coolant level to make sure it is full.

I have a 2004 ford expedition eddie bauer edition and my rear ac top vents are not blowing out any air


If this means that you have no rear air at all, the problem is a cheap resistor that you can replace. Ask a parts house to find the part and show you where it is located. You can do it and it's a cheap, easy fix. If some air is blowing out of other rear vents, then the problem may be a fan and not just the resistor. Air can be blowing out of the front vents like crazy and the problem with the back can be as I described sense front and back have separate resistors.

My 2005 Ford Expedition is blowing hot air from the front vents and suddenly the rear vents stopped working at all but I can sometimes hear a noise on the rear part of the truck ,may someone please tell me...


to me this sounds like a blend door problem. this is in the heater box, first you need to pinpoint the noise. there is 2 heater boxes on front and a rear both have blend doors. being you hear a noise, I suspect either door is jambed by forign object or broken, but still could be a problem with the actuator for the door. as for the rear not blowing?,check the position of the front blower switch, one position will disable rear function. honestly this
should be done by an experianced technican, I was 20yrs ford.

A/c problem


You either have a bad control, or motor running the air direction door in the front HVAC unit, or a door that is stuck.

The front and rear units are totally separate.

The door directs where the air, cold or hot, should come out, whether it is panel vents, floor, defrost, or any combination of those.

This door and motor are located inside the heater box which usually requires a lot of the vehicle dash assembly to be taken apart to get to these parts.
