Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety.
Ensure the vehicle is on a flat surface and the engine is off.

2. Check Refrigerant Level

Tools Required: Manifold gauge set.
Connect the low-pressure side of the manifold gauge to the service port.
Start the vehicle and turn on the AC to the maximum setting.
Check the gauge reading; if it's low, recharge the system with the appropriate refrigerant.

3. Inspect AC Compressor

Tools Required: Flashlight and safety goggles.
Locate the AC compressor in the engine bay.
Inspect for any visible leaks or damages, including cracked hoses or connections.
Ensure the compressor is engaging when the AC system is activated; if not, further diagnostics may be needed.

4. Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool (if applicable).
Locate the cabin air filter access panel, usually behind the glove box.
Remove the panel and take out the old cabin air filter.
Install a new cabin air filter, ensuring it is oriented correctly according to airflow direction.

5. Reconnect Battery

Once repairs are made, reconnect the vehicle's battery terminals.
Start the vehicle and test the AC system to confirm proper operation.
