Dodge Repair: Heater not blowing air, blower motor resistor, hex screws

Question
I have a 2001 Durango and the heater just stopped blowing air. I tested the blower motor and it works. Do you know where the relay and blower switch are located and is there a fuse for the heater? Do you know what the problem could be?
