I know its a old thread but I have had my truck for 10 plus years always sucked, e fan conversion upgraded compressor, red ford oriface a/c is super cold, evap cleaned then replaced still sucks ... well blows terrible. I have figured out perfect charge to make super cold, im finally fed up and im going to make it blow more air. I'm thinking pull dash port every chamber ? or maybe start with putting a way better blower. I will report back. if anyone has any ideas let me know. Im in AZ and I love this stupid truck, its blown with built motor and tran even has billet 3/4 hub, locker, stereo everything you can do lol, but still drive wifes Porsche more than I want because a/c sucks in summer. Sorry for grammar my teachers would cringe.
