2004 Expedition: The 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

Hello, Check your water hoses from the front heater core by using your hands when the engine has warmed up and running. You need to feel if the water is circulating through this front heater core. If one hose is cold, then the water valve is not opening and you need to determine why. You may have an auxillary heater core for the rear heater that is independent of the front unit.
If the system only has 1 heater core, then the obvious problem is in the ductwork flap activation. The solenoids are called "motors" and one is not opening for you.
There is a procedure for equipment used in the "High-End" Ford products with a Digital Climate Control system. These units are self-diagnosing when a particular activation Code is entered in them. It is accurate, fast, and you need a Codebook for a list of errors. For sure a Dealer has them and many Automotive Air Conditioner Repair places can use the system to diagnose your problem in under 5 minutes.
The problem is location. Only someone with a working knowledge of each vehicle will know where the parts are placed. It is easy to buy the parts and almost all are plug and play without any adjustments. But you don't want dash noises and squeeks after a novice tries to refit the dash.
I often recommend going to a Salvage yard and working on their vehicles to pull parts and understand how a certain vehicle disassembles. It will save you many broken fasteners and sometimes things that are hard to repair can be saved on your own vehicle from this experience.

you need to have automatic ac and heater control checked out at a garage problem could be in the mode switch or electrical problem causing front blend door actuator not working properly.your vechicle has the EATC SYSTEM which is computer control need diagnostie equipment to fix.
When I turn on the heat in my 2004 mazda mpv
the front air vents blow heat but the rear air vents are blowing cold. I have adjusted every setting is there something I am overlooking.
