Hello everyone. I have a 2002 tahoe with front and rear a/c. The rear a/c is blowing cold air but, the front is blowing hot air. The "door" that switches the air flow from hot to cold seems to be working. The line after the orifice tube is super cold. I don't know what else it could be. The pressure on the low side is about 40psi and the high side is about 200psi. I couldn't find any leaks anywhere. I'm going to try to get a better look at the temperature "door" when I get back home today. Anyone have some advice?
P.S. I live in Phoenix, AZ. The temperature outside lately is about 108.
