Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal to avoid electrical shocks.

2. Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister, safety goggles, gloves.
Attach the manifold gauges to the low and high-pressure ports of the AC system.
Start the engine and turn on the AC to the maximum setting.
If the refrigerant level is low, connect a refrigerant canister to the low-pressure side.
Open the valve on the canister slowly to add refrigerant until the gauge reads within the manufacturer's specifications.

3. Inspect and Replace the AC Compressor (if necessary)

Tools Required: Socket set, wrench set, AC compressor removal tool.
If the compressor is diagnosed as faulty, disconnect the electrical connector and remove the drive belt from the compressor.
Unscrew and remove the mounting bolts to detach the compressor from the engine.
Replace with a new compressor, ensuring all O-rings are lubricated and properly seated.
Reattach the mounting bolts and reconnect the electrical connector.

4. Check and Replace AC Condenser (if necessary)

Tools Required: Socket set, wrench set, leak detector.
Inspect the condenser for any visible damage or clogs.
If damaged, remove the mounting screws and disconnect the refrigerant lines.
Install the new condenser, reconnect the refrigerant lines, and secure with screws.

5. Test the System

Reconnect the negative battery terminal.
Start the engine and turn on the AC to the maximum setting.
Monitor the temperature from the vents to ensure it is blowing cold air.
