I had an issue like that in my old explorer the heat was on. the little valve that let engine coolant flow through the core was stuck open.

Even if you have and expansion valve instead of an orifice, it's still the least open spot in the system for flow and compressor debris will pile up in it.
I have seen where some expansion valves have a filter screen on their inlets to help keep any debris from clogging up the innards of the valve.

to check the blend door quickly just try the a/c when the car is cold after an overnight cool off, with cool coolant you should get cold a/c if all is working, if it gets warmer as the engine warms you know the blend door is the issue.

the cable has alot of tension on it and is pulling the gear that opens/closes the blend door off of the shaft...so it its forced shut by the air coming in...which pushes hot air through the ducts...ima play with the cable/gear and if i cant get it to work properly ill just force the door to stay open until winter comes around
