Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the negative battery terminal to prevent electrical shock.
Safety glasses and gloves should be worn.

2. Check and Replace Blower Motor Fuse

Locate the fuse box under the dashboard on the driver's side.
Identify the blower motor fuse (refer to the owner's manual for location).
Remove the fuse and check for continuity with a multimeter; replace if blown.

3. Inspect and Replace Blower Motor Resistor

Access the blower motor resistor, usually located near the blower motor itself.
Disconnect the electrical connector and remove the screws holding the resistor in place.
Replace with a new blower motor resistor and secure it with screws.
Reconnect the electrical connector.

4. Inspect Blower Motor

Remove any covers obstructing access to the blower motor.
Disconnect the electrical connector from the blower motor.
Test the blower motor directly by applying battery voltage; replace if not operational.
Reinstall the blower motor after testing.

5. Replace Cabin Air Filter

Locate the cabin air filter compartment, usually behind the glove box.
Remove the glove box for better access.
Take out the old cabin air filter and inspect for dirt or blockages.
Install a new cabin air filter, ensuring it is oriented correctly.
