Solution

1. Preparation

Tools Required: Safety glasses, gloves, manifold gauge set, OBD-II scanner.
Safety Warnings: Disconnect the battery before working on electrical components.

2. Check and Recharge Refrigerant

Sub-steps:
1. Connect the low-pressure gauge to the service port on the AC system.
2. Check the pressure reading; it should be within the manufacturer's specifications (typically 30-40 psi for low pressure).
3. If low, add refrigerant (R134a or R1234yf as per specifications) until the recommended pressure is reached.
4. Monitor the system for any leaks during this process.

3. Inspect and Replace AC Compressor (if necessary)

Sub-steps:
1. Remove the drive belt from the AC compressor using a wrench.
2. Disconnect the electrical connector from the AC compressor.
3. Remove the bolts securing the compressor and take it out of the engine bay.
4. Install the new AC compressor by reversing the removal steps, ensuring all seals are replaced and properly torqued.

4. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter compartment (usually behind the glove box).
2. Remove the glove box to access the filter.
3. Slide out the old cabin air filter and replace it with a new one, ensuring the airflow direction is correct.
4. Reassemble the glove box.

5. Check Electrical Components

Sub-steps:
1. Inspect the AC fuses in the fuse box for any blown fuses and replace them if necessary.
2. Test the AC relays; replace any that are defective.
3. Reconnect the battery and test the AC system operation.
