The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.

HVAC Blower Controls Circuit Description
The blower motor is a variable speed motor. The motor operates at a higher rate when voltage is increased to the maximum level.
The blower motor resistors reduce the voltage supplied from the A/C FAN fuse (LH IP Accessory Wiring Junction Block) when the blower control is set at low and medium speeds (speeds 1-4). The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.

The blower motor resistor is located under the dash on the passengers side between the blower motor and the fire wall. You will need to remove the hush panel first, also if you remove the blower motor the resistor will be easier to replace.

It is probably the blower motor resistor located on the passenger side
under the dashboard that is bad not the fuse.

Yes, generally the blower motor relay is located in backside of this devices, located under globe box (passenger side).

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

sounds like diode in motor burned out- replace motor

Just behind the blower motor is the blower motor resistor board.Under the dash just ahead of the passenger feet.

The blower motor resistor is located behind the glovebox mounted in the fan housing box under the dash.

If the blower moter only works on hi speed it is the blower motor resistor that is bad. The blower motor resistor is located under the passenger side of the dash next to the blower motor. It is not necessary to remove the blower motor to change the resistor.

If it's only working on high setting it is usually the blower resistor that needs replacing. They are usually located under dash, passenger side, remove cover, and it should be bolted or screwed near blower motor itself. $10-$20 part
