Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister
Instructions:
1. Attach the low-pressure side hose of the manifold gauge to the AC service port.
2. Start the engine and turn on the AC to the maximum setting.
3. Open the valve on the refrigerant canister and monitor the gauge to ensure the system is charged to the manufacturer's specifications (typically around 30-40 psi for low side).
4. Close the valve and disconnect the manifold gauge when done.

3. Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, AC compressor oil, new compressor
Instructions:
1. Remove the serpentine belt by loosening the tensioner with a wrench.
2. Disconnect the electrical connector from the AC compressor.
3. Remove the bolts securing the AC compressor and take it out.
4. Install the new AC compressor, ensuring to use the correct amount of oil as specified in the service manual.
5. Reconnect the electrical connector and reattach the serpentine belt.

4. Clean or Replace Cabin Air Filter

Tools Required: Socket set or screwdrivers
Instructions:
1. Locate the cabin air filter (usually behind the glove compartment).
2. Remove the glove compartment to access the filter.
3. Take out the old filter and replace it with a new one, ensuring it is oriented correctly.

5. Inspect and Clean Condenser

Tools Required: Water source, soft brush
Instructions:
1. Inspect the condenser for dirt and debris obstructing airflow.
2. Use a soft brush to gently clean the condenser fins.
3. Rinse the condenser with water to remove any remaining debris.
