Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shock.

2. Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister.
Sub-steps:
1. Connect the manifold gauge set to the high and low-pressure ports on the AC system.
2. Start the engine and turn on the AC to the maximum setting.
3. Check the pressure readings on the gauges; if low, proceed to recharge.
4. Attach the refrigerant canister to the low-pressure port and slowly open the valve to add refrigerant until the correct pressure is achieved.

3. Replace AC Compressor

Tools Required: Socket set, torque wrench, AC refrigerant recovery machine.
Sub-steps:
1. Recover the refrigerant using an AC recovery machine.
2. Disconnect the electrical connector and hoses from the old AC compressor.
3. Remove the mounting bolts securing the compressor and take out the old compressor.
4. Install the new compressor, securing it with bolts to the manufacturer’s specified torque values.
5. Reconnect the electrical connector and hoses.

4. Check and Replace Cabin Air Filter

Tools Required: None.
Sub-steps:
1. Locate the cabin air filter compartment, typically under the dashboard or behind the glove box.
2. Remove the cover by unclipping or unscrewing it.
