Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, vacuum gauge, refrigerant manifold gauge set, cabin air filter.
Safety Warnings: Always disconnect the battery before starting work on electrical components.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the climate control fuses using a fuse puller.
Inspect each fuse for continuity using a multimeter.
Replace any blown fuses with ones of the same amperage.

3. Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Locate the cabin air filter access door, usually behind the glove compartment.
Remove the old filter and clean the area.
Install the new cabin air filter, ensuring the airflow direction is correct.

4. Test and Replace Blower Motor (if necessary)

Access the blower motor, typically located under the dashboard on the passenger side.
Disconnect the electrical connector and remove any retaining screws.
Test the blower motor with a multimeter for continuity.
If faulty, replace the blower motor with a new unit, reconnecting the electrical connector and securing it with screws.

5. Recharge A/C System (if necessary)

Use the refrigerant manifold gauge set to connect to the A/C service ports.
Check the low and high side pressures to confirm if they are within specifications.
If low, follow refrigerant refill instructions, ensuring to use the correct type of refrigerant for the vehicle.
