Default a/c not blowing? HELP!!!

i just got a new truck and the people i bought it from said the a/c module was bad? when i turn the a/c on or even the vent nothing comes out? does anyone have any experience with this and maybe have a part # and description? thanks in advance.

well i changed the resistor which was burned up. the dealer gave me another one that looks different he said the part # changed. then it still doesnt blow so i changed the blower motor and it still doesnt blow!! i checked fuses too. i put a test light on the harness and it lights up. what else could it be?

Ya when the resiter went out on my truck it had melted part of the wiring harness that plugs into it, mostly just a black wire that was in the middle of the bigger plug i was just under warramty so i had a dealer fix it.
