Help with rear AC question

[Jason530]

I have been ripping into the rear AC, first i found a bad actuator and i will be replacing that, however now i am looking at a hot air or warm air situation. Research tells me that the expansion valve is probably bad but i wanted to ask here before calling a mechanic. In the picture attached the arrow shows the tube that is getting cold, cold enough to create moisture on it. I know very little about AC so any input is helpful.

This is a 2003 Eddie Bauer model expedition

Do you have a dog? If so, you may have a stopped up/blocked evaporator in the rear. Not flowing enough air to exchange heat to cool air across coil.

we bought that vehicle used, i was surprised when i took the back panel off and it looked like a dog blew up in there.

If the rear looks that bad, probably have some of the same in the front. After you brush it out & vacuum, Lysol it & make sure it drains well. You can save yourself a lot of $$$
