I would like ask you a quick question about my car a/c system. I have a Lexus is250 and my a/c stop working. When I add freon, the a/c blows cold but if I drive the car it will blow warm. I changed the compressor, condenser, dryer, and expansion valve; the condenser fan are working as well. When I'm adding freon for the first time, the pressure reads normal low 30, and high 225 and the outside temperature is 90. However, when it blows warm the low is 80-90 and high is 100-150 and the outside temperature. I'm using an a/c manifold.
