When you turn up the A/C heat in your truck and see no change in the amount of air coming from the vents you likely need to replace your blower motor.

The blower motor is designed to produce more air as you turn up the knob on your A/C system. However, when the blower motor fails the motor is no longer able to blow on high.

Once you have changed the factory blower motor that has failed on your truck you'll be able to control your A/C heat again.
