No back heat in Expedition, Blows cold air but front works fine

2000 Ford Expedition Eddy B., (front and back controls) I turn the heat on and it works in front, The back does not it only blows cold air, Or will even blow warm to cold off and on, But mostly cold air... I was told by Ford dealer it would cost me $800.00+ for a blower thing in the back panel on drivers side that controls the back temprature panel.. i opened panel in back and it seems to be blowing and moving just fine to me. What could this be and how can I deturmine a cheep and eay fix? Can someone tell me what to look for and walk me through it.
Thanks,
Michele

    That blend door diagram you show, would I find it in the back of the expedition in back panel on drivers side? I was told I have two blend door fan areas and the one that controlled the back vents etc. is in back of expedition on drivers side. So this is the only place I should be in correct, I dont have to take dash out or anything? Just wanting to know where to find this one blend door that controlls the back vents are at if this is my problem. I will check out the hot water vale thing tonight though. Thanks for the info.

Shelly,

Buy used parts at car-part.com. Look on page with * to find the cheapest part. Coud be your temp blend door (#2) may not be moving back and forth. Or, you are not getting hot water to the rear heater core.

You may have to crawl under the truck and feel the heater hoses to see if they are hot. You will find a group of 4 lines, 2 for heater and 2 for a/c. If hot, you know hot water is getting back to the heater core. If not, there may be a hot water vave that's not working. Not sure if EXP. has a water valve for rear.

Let us know what you you find. Good luck.

    Yes, only one in back. No, you don't need to take dash apart.



    report back on findings.

My heat works great in the front but the rear vents only blow cold


The blend door actuator is located in the left rear quater panel. It's right there when you remove the trim panel (left side rear) Below is a picture of it when panel is removed along with another picture of the air duct system. I also gave you a picture of the connector at the actuator. Make sure you are geting power and test opening and closing. Worst case you could make the blend door stay to where you are geting heat until you can repair the problem...11_6_2012_12_34_03_am.jpg11_6_2012_12_34_21_am.jpg11_6_2012_12_34_35_am.jpg11_6_2012_12_34_48_am.jpg

In my 1998 ford expedition the air works fine then when the truck hits a bump or I turn the wheel sometimes it clicks off. After a few minutes it will turn back on. You can hear it click off when this...


there is a "flap" like you say inside the blower box that mixes hot and cold air. in my 93 mustang this flap is controlled by a vacuum line, check for a vacuum leak? on a newer vehicle it may not be vacuum activated, but this flap is most likely the problem

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

MY AIR CONDITIONIER ON 97 FORD EXPIDITION BLOWS HOT AIR IN THE FRONT, YOU CAN TURN THE AIR OFF AND THEN BACK ON AND IT WILL WORK SOME TIMES FOR A LITTLE WHILE. SOME TIME IT WORKS OK FOR A COUPLE OF DAYS....


The hot and cold air in the front is controlled by an actuator in the dash. The temp controller is working as designed because the back is working fine. You need to take to local shop to have the vent actuator or heater control box inside changed out. Then the tempaturer controller has to be reset. Good luck

Heater is blowing but its cold air not hot air 2000 expedition


Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

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.
