Solution

1. Preparation

Tools Required: Safety goggles, gloves, refrigerant gauge set, OBD-II scanner, basic hand tools (socket set, screwdrivers).
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery for safety.

2. Check and Recharge Refrigerant

Sub-steps:
1. Connect the low-pressure side of the refrigerant gauge to the AC service port.
2. Read the pressure gauge; if it is low, proceed to recharge the system.
3. Add refrigerant according to the manufacturer's specifications (typically R-134a for this model).
4. Monitor the pressure while adding refrigerant to avoid overcharging.

3. Inspect and Replace the AC Compressor

Sub-steps:
1. Remove the drive belt by loosening the tensioner and sliding the belt off the AC compressor.
2. Disconnect the electrical connector from the AC compressor.
3. Remove the AC lines connected to the compressor using the appropriate wrench, and capture any refrigerant in compliance with local regulations.
4. Unbolt the compressor from its mounting bracket and remove it from the engine bay.
5. Install the new compressor by reversing the removal steps, ensuring all connections are tight and secure.

4. Check and Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter compartment, usually behind the glove box.
2. Remove the glove box to access the filter.
3. Take out the old filter and inspect it for dirt or blockages.
4. Install a new cabin air filter in the correct orientation.

5. Final Assembly

Reconnect the battery.
Replace the drive belt and ensure proper tension.
Start the engine and turn on the AC to verify functionality.
