Is there a reason why condensation would be dripping from a van that isn't blowing cold when the AC is set to Max and recirculate? It's a 99 Chrysler Town and country. It is a manual temp control unit.

most automotive a/c units have a low pressure sensor on or near the dryer ,so if it go low the unit will not engage so im saying its the door in the unit that switches from hot to cold or visa versa ..it is usually controlled by a cable or vacuum operated switch the door and or cable connect usually on the passenger side under the dash you may have to pull the glove box to access or get a flashlight and look under the passenger side while moving the switch on the controls a cable will sometimes work lose if so is an easy fix usually put it back on by hand sometime requires a screwdriver of a lose screw holding clamp that holds cable in place ,,if it is vacuum operated then you have to find the leak and replace hose could be under the hood for vacuum hose broken or came lose hope this helps
My vote is for the blend door. If its a manual AC system, the blend door should be directly connected to the temp nob - on my Early 2000 and later 1990s Chyrsler it was a cable. On 2000 Durango, the cable came off and the blend door was stuck in one position. Cable was accessible just above glove box (I think I had to remove the glove box). There was noticeably less tension on the control knob.
