Solution

1. Preparation

Gather necessary tools and parts.
Ensure safety gear is worn (gloves and goggles).
Disconnect the vehicle battery to prevent electrical shock.

2. Recharge Refrigerant

Tools Required: Refrigerant gauge, refrigerant canister.
Connect the refrigerant gauge to the low-pressure service port.
Check the pressure readings; if low, proceed to recharge the system.
Follow the instructions on the refrigerant canister to add refrigerant, ensuring the system reaches the correct pressure.
Disconnect the gauge and reconnect the service port cap.

3. Inspect and Replace Components

Tools Required: Socket set, screwdrivers, multimeter.
Inspect the AC compressor; if it shows signs of failure (e.g., clutch not engaging), replace it.
If the cabin air filter is dirty, remove and replace it with a new one.
Check the AC blower motor; if it is faulty, replace it.

4. Check for Leaks

Tools Required: UV leak detector kit, flashlight.
Use a UV dye in the refrigerant and run the AC for a few minutes.
Inspect all connections and hoses under UV light for dye leaks.
Repair or replace any leaking components as necessary.

5. Reassemble and Test

Reconnect any components removed during inspection.
Reconnect the vehicle battery.
Start the engine and turn on the AC to test for proper operation and cooling efficiency.
