Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, replacement fuses, cabin air filter.
Disconnect the vehicle battery to avoid electrical short circuits.

2. Inspect and Replace Fuses

Locate the fuse box (usually in the cabin or engine compartment).
Use the fuse puller or pliers to remove the fuses related to the climate control system.
Check the fuses visually and with a multimeter for continuity.
Replace any blown fuses with new ones of the same amperage.

3. Cabin Air Filter Replacement

Open the glove compartment and remove any contents.
Locate the clips or screws securing the cabin air filter cover and remove them.
Take out the old cabin air filter and inspect for dirt or debris.
Install the new cabin air filter, ensuring the airflow direction is correct.
Reattach the filter cover and secure it.

4. Blower Motor Inspection

Access the blower motor, usually located under the dashboard on the passenger side.
Disconnect the electrical connector from the blower motor.
Use a multimeter to check for voltage at the connector when the climate control is activated.
If there is voltage and the motor does not operate, replace the blower motor.
If there is no voltage, check the wiring harness for damage.

5. Refrigerant Level Check

Connect a manifold gauge set to the AC service ports.
Start the vehicle and turn on the AC to the maximum setting.
Read the pressure levels on the gauges; they should be within the manufacturer's specified range.
If the refrigerant is low, carefully recharge the system with the appropriate type of refrigerant.
