Disconnect the negative terminal of the battery to prevent electrical shock.

2. Replace Blower Motor Fuse

Locate the fuse box; refer to the owner's manual for the specific fuse related to the blower motor.
Remove the blown fuse using a fuse puller or needle-nose pliers.
Insert a new fuse of the same amperage.

3. Replace Blower Motor Resistor

Remove the lower dashboard panel or cover to access the blower motor resistor.
Disconnect the electrical connector from the resistor.
Unscrew and remove the old resistor from its mounting location.
Install the new blower motor resistor and reconnect the electrical connector.
