Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, refrigerant gauge set, basic hand tools (socket set, wrenches), and safety goggles.
Ensure the vehicle is parked on a flat surface and the engine is off. Disconnect the battery to avoid electrical hazards.

2. Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister.
Attach the refrigerant gauge to the low-pressure service port of the AC system.
Start the engine and turn on the AC to the maximum setting.
Slowly add refrigerant until the pressure readings are within the manufacturer's specified range.
Monitor the system for any unusual noises or leaks during the process.

3. Replace AC Compressor (if necessary)

Tools Required: Socket set, wrench set, AC compressor removal tool.
Disconnect the battery once again for safety.
Remove the serpentine belt by loosening the tensioner and sliding the belt off the AC compressor.
Detach the AC lines from the compressor, being cautious of any residual refrigerant.
Unbolt the AC compressor from the mounting bracket and remove it from the engine bay.
Install the new AC compressor by reversing the removal steps, ensuring all fittings are secure.

4. Check and Replace Fuses (if necessary)

Tools Required: Fuse puller or pliers.
Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the AC-related fuses using the diagram on the fuse box cover.
Remove any blown fuses and replace them with new ones of the same amperage.

5. Final Checks

Reconnect the battery and start the engine.
Turn on the AC and monitor for proper operation and cooling.
Check for any leaks in the AC system after repairs.
