i own a 91 accord wagon........... the ac unit is working but when u turn it on nothing but hot *** heat is blown at u........... i figure it could be the freeon that they put in the ac unit it might have to be added but i feel there is something else wrong. becuase even with teh a.c off and the **** turned to cool it still blows hot *** air.......... i dont remeber the name but a friend of mine told me it might be this valve that opens and closes and it might be stuck on hot. could this be true? what should i look for to try to get this fixed cause so cal heat is deadly dammit

 

yup, he's right about the heater control valve maybe still stuck open, there's a couple threads that i've skimmed over already about this vent door...
