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 prevent electrical issues.

2. Inspect AC Compressor

Locate the AC compressor in the engine bay.
Visually inspect for any debris or damage around the compressor.
If debris is found, carefully remove it and test the AC system again.

3. Check AC Belt

Inspect the AC belt for signs of wear, cracks, or fraying.
If the belt is damaged, loosen the tensioner and remove the old belt.
Install a new belt, ensuring it is properly aligned and tensioned according to manufacturer specifications (typically around 10-20mm of deflection).

4. Examine Blower Motor

Access the blower motor, which is usually located behind the dashboard.
Remove any screws or clips securing the blower motor.
Inspect for foreign objects inside the blower motor housing and remove any found.
Reassemble and test the blower motor operation.

5. Replace Cabin Air Filter (if necessary)

Locate the cabin air filter access panel, typically found behind the glove compartment.
Remove the panel and take out the old cabin air filter.
Install a new filter, ensuring it is oriented correctly.

6. Final Assembly

Reconnect the negative battery terminal.
Start the vehicle and turn on the AC to check for any remaining noise.
