3. Inspect and Replace Components

Inspect AC Compressor
- Check for any visible leaks or damage.
- If the compressor is faulty, remove it by:
  1. Disconnecting the electrical connector.
  2. Removing the drive belt using a socket set.
  3. Unbolting the compressor from its mounting points.
  4. Installing a new compressor by reversing these steps, ensuring all bolts are torqued to manufacturer specifications.
Check and Replace Expansion Valve
- Locate the expansion valve and inspect it for blockages.
- Remove the expansion valve by disconnecting the refrigerant lines and securing it with a socket set.
- Install a new expansion valve, ensuring to replace O-rings to prevent leaks.
Replace Cabin Air Filter
- Open the glove box and remove it to access the cabin air filter compartment.
- Take out the old filter and install a new one, ensuring proper orientation.
