Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check Refrigerant Level

Tools Required: Manifold gauge set
Connect the low-pressure side of the manifold gauge to the AC service port.
Start the engine and turn on the AC to max settings.
Read the gauge; if the pressure is low, it indicates a refrigerant leak or insufficient charge.
If necessary, recharge the system using the appropriate refrigerant (R134a or R1234yf as specified).

3. Inspect and Replace the AC Compressor

Tools Required: Socket set, wrench set, refrigerant recovery machine
Remove the drive belt from the AC compressor.
Disconnect the electrical connector from the compressor.
Remove the bolts securing the compressor to the engine block.
Carefully lift out the old compressor and replace it with a new one.
Reinstall the bolts and reconnect the electrical connector.

4. Clean or Replace the AC Condenser

Tools Required: Hose, cleaning solution (if cleaning), new condenser (if replacing)
Locate the AC condenser in front of the radiator.
If cleaning, spray a cleaning solution and rinse with water to remove debris.
If replacing, disconnect the refrigerant lines, remove the old condenser, and install the new unit.
Reconnect the refrigerant lines and ensure all seals are tight.

5. Test the System

Reconnect the negative battery terminal.
Start the engine and turn on the AC to the max setting.
Monitor the AC performance and check for cold air blowing from the vents.
