Hello all and thank you for your help. I have a 92 Vigor recently my a/c went out and I'd just refilled the freon. But for some reason on my pasenger side one of the vent blows out cold air and the rest blows out warm air. I already replace the valve box behind the fire wall "that has a black plastic cover on it". I really need help.... I feel like a freakin melted popsicle Thank you
