It is a device with multible resistors that controls the speed of a blower motor.
The HVAC resistor pack is used to provide the various speeds of the blower motor for heating and A/C. According to other sources, the resistor pack mounts to the rear of the blower motor, which is located under the passenger side dash.
The 2005 Ford F1 50 pickup truck blower motor resistor pack can be found on the firewall in the engine compartment. The blower motor resistor pack is on the passenger side of the firewall.
If the fan works on at least one of the settings then it most likely the resistor pack. The fan either works or doesn't work.
Either it's the switch on the dash (unlikely) or the blower motor resistor pack (very likely). The resistor pack is usually easy to replace.
If you are referring to the blower motor resistor, it is located behind the glove box and in the heater case.
the resistor pack is situated passenger side under glove box, behind the right side foot well trim towards the back. A few screws hold this in place. My son changed the resistor for me today.
There is a Blower Motor Resistor Pack. Either the blower motor speed control switch itself is defective or the Resistor Pack is bad.
