Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety.
Ensure the vehicle is parked on a level surface.

2. Replace Cabin Air Filter

Tools Required: Screwdriver, new cabin air filter
Remove the glove compartment by unscrewing the hinges and gently releasing it.
Locate the cabin air filter housing; remove the cover.
Take out the old cabin air filter and inspect for dirt or blockages.
Install the new cabin air filter, ensuring it fits securely.
Reattach the housing cover and the glove compartment.

3. Inspect and Replace AC Blower Motor (if necessary)

Tools Required: Socket set, multimeter
Access the blower motor by removing any panels obstructing it (often located under the dashboard on the passenger side).
Disconnect the electrical connector from the blower motor.
Use a multimeter to test for voltage at the connector while the AC is on; if no voltage is present, further electrical diagnostics may be required.
If the blower motor is faulty, unbolt it from the assembly and remove it.
Install the new blower motor and reconnect the electrical connector.

4. Check Ductwork for Blockages

Tools Required: Flashlight
Visually inspect the ductwork for any visible blockages or debris.
If blockages are found, carefully remove them to restore airflow.
Ensure all duct connections are secure and free of leaks.
