Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister, manifold gauge set.
Sub-steps:
1. Connect the low-pressure side of the manifold gauge to the service port on the AC system.
2. Start the engine and turn the AC to the maximum.
3. Check the pressure readings; if low, proceed to recharge the system.
4. Attach the refrigerant canister to the manifold gauge and open the valve to allow refrigerant to flow into the system.
5. Monitor the pressure until it reaches the manufacturer's specifications.

3. Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool.
Sub-steps:
1. Locate the cabin air filter compartment, usually under the dashboard or behind the glove box.
2. Remove the cover by unscrewing or unclipping it.
3. Take out the old cabin air filter and inspect for dirt or blockages.
4. Install the new cabin air filter, ensuring it is oriented correctly.
5. Reattach the cover securely.

4. Inspect and Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, AC compressor removal tool.
Sub-steps:
1. Disconnect the electrical connector from the compressor.
2. Remove the serpentine belt by releasing the tensioner.
3. Unscrew and remove the mounting bolts holding the AC compressor.
4. Carefully remove the compressor from the engine bay.
5. Install the new compressor by reversing the removal process, ensuring all bolts are torqued to specifications.
