Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shocks.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Check the HVAC-related fuses using a fuse puller or pliers.
Replace any blown fuses with new ones of the same amperage.

3. Check and Replace Cabin Air Filter

Open the glove compartment and remove it by detaching the damper arm.
Locate the cabin air filter housing, usually behind the glove compartment.
Remove the old cabin air filter and inspect for dirt or blockage.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Test the Blower Motor

Reconnect the battery and turn on the ignition without starting the engine.
Activate the fan switch to check if the blower motor operates.
If no sound is heard, proceed to check the electrical connections at the blower motor.

5. Replace the Blower Motor (if necessary)

Disconnect the wiring harness from the blower motor.
Remove any screws or clips holding the blower motor in place.
Replace with a new blower motor and securely fasten it.
Reconnect the wiring harness and retest the fan operation.
