2. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter access panel, usually found behind the glove compartment.
2. Remove the glove compartment by detaching any screws and gently pushing it down.
3. Open the access panel and remove the old cabin air filter.
4. Clean the area with a vacuum cleaner to remove any debris.
5. Install a new cabin air filter, ensuring it is oriented correctly for airflow direction.
6. Reattach the access panel and glove compartment.

3. Recharge Air Conditioning System

Sub-steps:
1. Locate the low-pressure service port on the A/C system.
2. Connect the refrigerant recharge kit to the service port.
3. Check the pressure and add refrigerant if low, following the manufacturer's specifications.
4. Disconnect the recharge kit and check for leaks.

4. Test and Replace Blower Motor (if necessary)

Sub-steps:
1. Access the blower motor by removing the lower dashboard panel on the passenger side.
2. Disconnect the electrical connector and remove the blower motor mounting screws.
3. Pull out the blower motor and visually inspect it for damage.
4. If faulty, install a new blower motor and reconnect the wiring.
5. Reattach the lower dashboard panel.
