Vacuum leak
Sounds like the switch broke (the one that directs the air valve) or disconnected somewhere along the shaft.
It only stays on when the air flow is turned to defrost. It does this because the air condition has a dryer on it that dries the air which defrosts the windshield better.
Check the vacuum supply from the engine. If it is disconnected or cracked the system will default to defrost only.
If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
no, only with defrost or ac on or if coolant temp is hot enough
There is most likely a vacuum leak on the line from the engine to the air conditioner control.
Cooling fan is designed to come on only when A/C, defrost, or engine temperature exceeds 235 degrees
The vacuum supply line from the engine is disconnected or broken. When the vacuum supply is cut off the system defaults to the defrost mode.
I get hot air coming out of my air conditioner on the passenger side, while I get cold air coming out the drivers side. Can you tell me why and how do I find the schematic to fix it?

That is condensation and it is normal for water to come out of an air conditioner in the back of it.
