Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid electrical shock.
Ensure the vehicle is on a level surface and the engine is off.

2. Inspect AC Components

AC Compressor:
- Remove the plastic cover if necessary.
- Check for any visible cracks or damage.
- If foreign objects are found, carefully remove them.
Belt Inspection:
- Inspect the AC belt for fraying or cracks.
- Use a torque wrench to adjust or replace the belt if necessary; torque specifications for the belt tensioner should be followed as per the service manual.

3. Check the Blower Motor

Remove the blower motor cover, if applicable.
Inspect for debris or blockages.
If necessary, remove the blower motor by disconnecting the electrical connector and unscrewing it from its housing. Replace with a new unit if defective.

4. Test AC System Functionality

Reconnect the battery.
Start the engine and turn on the AC to check for noise.
Ensure the AC compressor engages smoothly without any clicking.
