The blower resistor pack for a 2002 Toyota Highlander is located under the dashboard on the passenger side of the vehicle, typically near the blower motor. To access it, you'll need to remove the lower dash panel and possibly some additional components to reach the resistor pack. It's usually mounted directly to the heater box and has a wiring connector attached. Make sure to disconnect the battery before attempting any repairs.
Defective Blower Motor Resistor Pack.
It can be the resistor pack on the evaporator case.
Possibly defective Blower Motor Resistor Pack.
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.
There is a Blower Motor Resistor Pack. Either the blower motor speed control switch itself is defective or the Resistor Pack is bad.
Blown fuse, defective blower motor, or defective blower motor resistor pack.
First check the fuse to see if it is blown. If the fuse is good, then it is either the blower motor switch, blower motor Resistor Pack, or the Blower Motor itself. It can also be bad wiring. Apply 12 volts directly to the blower motor to see if it is good. If it is good and the wiring it OK, then it is the switch or resistor pack. I would bet on the Resistor Pack being the culprit. The switch rarely goes bad..
Either the blower motor fan switch is bad or the blower motor resistor pack is defective. It is more than likely the blower motor resistor pack.
If there is a second blower motor and speed control for the rear air, then there is also a second Resistor Pack. It will be located near the rear blower motor. Exactly I cannot say. Follow the wiring.
If it works on some speeds and not others, the most likely problem is a defective Blower Motor Resistor Pack. It is located near the 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.
: My 2002 focus blower fan worked at the highest setting only and not 1,2 and 3. I fixed it by replacing the blue resistor pack held down by 1 screw behind the glove box next to the blower motor. : At first I checked the power supply to the blower motor connector. I was getting power only at setting 4 and none at other settings. : Fan blower electrical diagram showed that the only connection to the fan blower is the power supply, resistor pack and front panel switch.
