Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety when working on electrical components.

2. Check and Recharge Refrigerant

• Tools Required: A/C refrigerant gauge set, refrigerant canister, safety glasses, gloves.
• Sub-steps:
  1. Attach the low-pressure gauge to the service port on the A/C system.
  2. Check the pressure reading; if below the manufacturer's specification, the system is low on refrigerant.
  3. Add refrigerant as necessary while monitoring the pressure gauge, ensuring not to overfill.
  4. Disconnect the gauge and replace the service port cap.

3. Inspect and Replace A/C Components

• Tools Required: Socket set, screwdrivers, A/C compressor replacement (if necessary), O-rings.
• Sub-steps:
  1. If the compressor is not engaging, check the electrical connections and fuses.
  2. If faulty, remove the A/C compressor by disconnecting the electrical connector and the refrigerant lines (ensure to recover refrigerant properly).
  3. Install the new A/C compressor and replace O-rings.
  4. Reconnect the refrigerant lines and electrical connections.

4. Replace Cabin Air Filter

• Tools Required: Screwdriver (if needed for panel removal).
• Sub-steps:
  1. Locate the cabin air filter compartment, typically under the dashboard.
  2. Remove the panel covering the cabin air filter.
  3. Take out the old filter and replace it with a new one.
  4. Reattach the panel securely.
