Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Repair Leaks

Tools Required: UV leak detection kit, refrigerant dye
Add UV dye to the refrigerant system.
Run the A/C for at least 10 minutes and inspect all connections, hoses, and the compressor for leaks using a UV light.
If leaks are found, replace the damaged components (hoses, seals, or the compressor).

3. Recharge the A/C System

Tools Required: A/C manifold gauge set, refrigerant
Connect the manifold gauges to the service ports.
Follow the manufacturer's specifications to add the appropriate type and amount of refrigerant.
Monitor the gauge readings to ensure proper pressures are achieved.

4. Replace Cabin Air Filter

Tools Required: Screwdriver (if applicable)
Locate the cabin air filter compartment, typically behind the glove box.
Remove the old filter and inspect for dirt or blockages.
Install a new cabin air filter according to specifications.

5. Test the A/C System

Reconnect the battery.
Start the vehicle and turn on the A/C to check for proper operation and airflow.
Listen for any unusual noises from the compressor.
