A good place to start would be the resistor pack, they are notorious for failing in any breed of truck. Mine had full blast only until I removed the resistor pack and re-soldered a tab back in place.
Check the wires leading to the resistor pack as well, make sure a different wire has power on different settings of the switch. Hope that helps.
