1) Check your antifreeze level. 2) I have a explorer sport trac and after changing the heater core(pain in the a#$) I found out it was the heater control valve. Not sure if the expedition has this, but it is an easy fix if it does. It is plastic and has a little ball valve inside. The ball gets stuck closed. Good luck!

I have a 2003 Expedition and the front heat works but rear blows cold air. Any advice?


Well the first thing I would want to know is if the rear heater core is getting hot.
You can check the heater hoses if they are accessable, or pull the cover off the unit next to the third row seat and check the core.

2003 ford expedition air condition works fine hot air doesnt work


If both heater hoses are getting hot, it could be a blend door problem under the dash.
The blend doors direct air thru the heater core and the vents.

Why does my 2004 ford expedition air conditioner go in and out?


there are several ways that system can fail if your saying it blows cold then hot it may just be low on charge if the hvac fan quits and everything goes dead then its uaslly a electrical connectoin problem to the hvac module head thats also called the control panel if its just the fan check the connector at the fan when its running if it goes off then try to replace the connector.

My husband needs to know if there is a fuse that could fail and make the rear air conditioner blow hot air.


no....This is the rear A/C & heater actuator blend door malf/broken. This is very common on expeditions and I encountered the same issue in my 2006 expy. This door switches from hot to cold vents, once stuck only hot air will blow. Also, is there any thumping or tapping noises from the right rear panel (this is where the rear a/c unit is)???

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

My 2003 EB had the same issue, until I took it to my local dealer. There is a TSB that calls for this part to be replaced.You need the following part number: 2L1Z19C828AA - HOS ASY-A/C VAC
