My heater/AC fan only works on high. how do i get the low and medium settings to work? ---

This is almost certainly a problem with the blower motor resistors. ---

The blower motor resistor pack is likely shot, and replacing it will likely solve the problem. If you install a new resistor pack and your fan speeds start working again, you should check your current draw on your blower motor. A dragging blower motor will cause the truck to eat resistor packs. If the motor is drawing too much current, it needs to be replaced. ---

thanks! I’ll look into this.
