Solution

1. Preparation

Gather tools: screwdrivers, socket set, multimeter, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace the Cabin Air Filter

Locate the cabin air filter housing, typically found behind the glove compartment.
Remove the glove compartment by detaching the screws or clips.
Take out the old cabin air filter and inspect it for dirt and blockages.
Install a new cabin air filter, ensuring it is oriented correctly based on airflow direction.

3. Check and Replace the AC Fuse

Locate the fuse box, usually under the dashboard or in the engine compartment.
Identify the AC blower motor fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity with a multimeter; if blown, replace it with a fuse of the same amperage.

4. Test and Replace the Blower Motor (if necessary)

Reconnect the battery and turn on the ignition without starting the engine.
Set the AC controls to the highest fan speed and listen for the blower motor operation.
If the blower motor does not operate, disconnect it and check it with a multimeter for continuity.
If defective, remove the blower motor by unscrewing it from its housing and disconnecting the electrical connector.
Install the new blower motor by reversing the removal steps, ensuring all connections are secure.

5. Reassemble and Test

Reattach the glove compartment and any other components removed during the process.
Reconnect the battery.
Start the engine and test the AC system to verify that air is blowing from the vents.
