The rear fan/ blower motor may have died before you got the vehicle. if it worked for you at one time, the blower usually makes noise before biting the dust, so you can check fuses and relays, as well.

SOURCE: 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.

SOURCE: 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.

  1. Disconnect the blend door actuator electrical connector.
  1. To install, reverse the removal procedure.

SOURCE: front vents do not work, a/c is blowing through

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.

SOURCE: I have a 2006 Ford Expedition. The Air

you have a vacuum loss to the ac control head, the motors that divert air are vacuum operated, if you loose vacuum the system goes to defrost for safety reasons, the vacuum comes from the engine, then goes o a plastic vacuum tank under the hook start there, it is a 3/16 id hose.

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.

Rear window switchs wont work but Drivers works all windows,


This may be a problem with Ford Expedition in which a class action suit should help resolve. I also had a 2001 and a 1997 expedition which had the same problems. I traded the 1997 in for the 2001 and later bought a replacement arm operator for the rt passenger rear side. i did not get a chance to install due to a recent accident in which I totaled the vehicle--quick fix for me:)
