Its from the ceiling. I turn the a/c on from the front and its cold but when I turn on the back its always warms like the outside air. Im trying to avoid paying hundreds of dollars to fix. So if I can get some help from others that has had this problem it would make things easier.
 
Thank you in advance for any help.

That's a vac leak. Common spot is where the vac lines go under the battery tray.

What happens when you adjust the temperature knob, do you hear clicking or thumping in the rear passenger side?

I have this same issue. I did not have a thumping / clicking noise but I changed both actuators since I had the trim torn out anyways. Still can't figure out why I'm getting ambient air out of the rear a/c. When the temp is turned to hot, the air gets hot, as expected. When turned to cold, the air cools down(ambient air) but not air conditioned.

Do I have to replace the vac hoses totally? and what is the price I will have to pay to fix this problem?
 
Thank you in advance for your help.

Doing some more research, sounds like it could be a clogged / failed rear expansion valve? Anyone have any experience with changing a rear expansion or even suspect that it could be causing unconditioned air to blow out of rear vents?

Changed out the rear expansion valve. The kids complained last night that they were too cold.

#199 of 232 Rear AC Problem by logokster

Jul 10, 2011 (7:53 pm)

Hi. I have a 2005 Expedition with similar but maybe slightly different rear ac issues. A little over a month ago I had a clicking and thumping sound coming from the rear. Based on forums I narrowed the problem down to the air blend actuator which controls the floor to ceiling air flow. Then yesterday, I started hearing the clicking sound again when in the rear ceiling setting. Did my actuator really go bad in a little over a month? On top of that, last night (about an hour of driving after the clicking started), the AC in the entire vehicle stopped working. So front and back blows out warm air when set to the coldest setting and hot air when set to hot. There is also a new noise that started when the AC turned warm. I am not good at describing sounds but maybe like a whistle / grinding. Kind of like when your brake pads are wearing down, I think it is related to air flow. Weird thing is when you hit the throttle the sound changes pitch but comes back. I do not believe the side actuator which controls the temperature is bad but who knows (there is no clicking from this and I can feel it turn when I change the temperature).
