superman4k6 Posted June 20, 2015 Share Posted June 20, 2015 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. Quote Link to comment Share on other sites More sharing options...
clubfoot Posted June 21, 2015 Share Posted June 21, 2015 Most moder bay cars don't use freon, if I'm not mistaken. Did you change your cabin filter (glove box) before it stopped working? Quote Link to comment Share on other sites More sharing options...
