Re: A/C Mystery... help

#1 make sure auxillary fan is working,electric fans in front ,behind radiator,should work with ac on,both fans
#2 heater control valve or hot water valve bad,stuck in the open position allowing water ,aka hot coolant into evaporator area making cool air hot
#3 ac low on charge or over charged ,ac will blow out warm air if overcharged
