A little background alternator died / car stalled while driving. replace the alternator and the a/c stopped working. So i figured the most common part that would go is the resistor, so i bought a new one and swapped , a/c still wasnt working a few day of playing with it i noticed that when i put a new resistor in the slide in there opens (there's a slide to the actual blow motor fan itself, when resistor is bad or out it is in closed position) so i rolled up a newspaper and gave it a kick start, and that's my fix. Hope this could help someone...
