2. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister, safety goggles, gloves.
Sub-steps:
1. Connect the manifold gauge set to the AC service ports.
2. Check the low and high-pressure readings.
3. If the refrigerant level is low, add the appropriate type of refrigerant as specified in the owner's manual.
4. Monitor the pressure and ensure it reaches the manufacturer's specifications.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, refrigerant recovery machine (if necessary), safety goggles, gloves.
Sub-steps:
1. If the compressor is not engaging, test the electrical connections and fuses related to the AC system.
2. If faulty, disconnect the refrigerant lines and electrical connections from the compressor.
3. Remove the AC compressor mounting bolts and take out the compressor.
4. Install the new compressor, ensuring all connections are secure and the mounting bolts are torqued to specification.

4. Verify and Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool.
Sub-steps:
1. Locate the cabin air filter housing, usually behind the glove box.
