Solution

1. Preparation

Gather tools: OBD-II scanner, refrigerant gauge, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a level surface and the engine is off before starting repairs.

2. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter access panel, typically found behind the glove box.
2. Open the glove box and remove any contents.
3. Release the stops on the sides of the glove box to allow it to drop down.
4. Remove the access panel to the cabin air filter.
5. Take out the old filter and replace it with a new, clean filter.
6. Reassemble the access panel and glove box.

3. Recharge A/C System

Sub-steps:
1. Connect the refrigerant gauge to the low-pressure service port of the A/C system.
2. Start the engine and activate the A/C at maximum settings.
3. Check the gauge reading to determine if refrigerant is low.
4. If low, add the correct type and amount of refrigerant according to specifications.
5. Disconnect the gauge and check for proper A/C operation.

4. Inspect and Replace Blower Motor

Sub-steps:
1. Disconnect the vehicle's battery to prevent electrical shock.
2. Locate the blower motor, typically found under the dashboard on the passenger side.
3. Remove any screws or clips securing the blower motor.
4. Disconnect the electrical connector from the blower motor.
5. Remove the faulty blower motor and replace it with a new unit.
6. Reconnect the electrical connector and secure the motor with screws or clips.
