New guy with A/C question
Second, I have a 2000 F-250 4X4 7.3L, mbrp 4" turbo back stack kit, hypertech programmer, afe air filter - anyway my question is my a/c blows warm air when i stop at a red light or slow down below 20 mph. I've checked the freon charge and the fan clutch. The book i have mentions a pressure cycling switch located on the dryer. Could this be my problem? when traveling at highway speeds it gets good and cold. I live in south Mississippi so i need the a/c all the time! Any help would be greatly appreciated.
