Air/Heater Problem

My car will not blow any air at all. Cold/Hot it wont turn on. I put it on max and min doesnt blow anything. What can be wrong?

Check for blown fuse. If blown fuse is not the problem, put blower switch on high and smack the blower motor (located by passenger footwell) with rubber hammer or similar. If the blower motor starts blowing, the problem is with the motor (worn out brushes, etc). Finally, the problem could be with the resistor pack.
