No Heat!

When I turn the knob, no air blows, regardless of the setting, heat or AC. I know that my AC doesn't work, but in the current 26 degree weather, it is less of a problem. The heat however is sorta important.

Like I said, nothing happens when I turn the knob. Could it be the blower motor?

Cehck if theres power to the blower motor switch, then see if theres power to the motor, when that happens its usually the blower motor resistor
