Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, and screwdrivers.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace Blower Motor Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the blower motor fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Replace with a new fuse of the same amperage.

3. Inspect and Replace Blower Motor

Access the blower motor, usually located under the dashboard on the passenger side.
Remove any necessary panels or covers to reach the blower motor.
Disconnect the electrical connector from the blower motor.
Remove the motor by unscrewing the mounting screws.
Install the new blower motor and reconnect the electrical connector.

4. Check HVAC Control Module

Reconnect the battery.
Turn on the ignition and check the HVAC control module for proper operation.
If the module is faulty, replace it according to the manufacturer's specifications.
