hey guys. ive been having trouble with my a/c; ive looked everywhere and cant find my problem so any help is greatly appreciated. heres the problem: im in college and i like to drive home occationaly but on long trips my a/c stops blowing. the fan gradually slows to a stop but the air remains cold. i had been told that it could be the blower or the resitior pack. i dont think it is these because they were replace about one year ago. when those were replaced the problem was different. then the fan stopped blowing abruptly, now it slows to a stop.

i had my a/c sytem checked at pep boys and they found nothng wrong.

i tried pulling the codes but nothing there. i dont know what to do. i gotto school in waco tx, there is not dealership close that i know of nor any mechanic knowlegable whith volvos that i know of either. so once again any help is greatly apprechiated
