Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shocks.
Gather necessary tools and parts.

2. Recharge Refrigerant

Tools Required: AC refrigerant gauge, refrigerant canister, manifold gauge set.
Check the refrigerant level with the gauge; if below the recommended level, proceed to recharge.
Connect the refrigerant canister to the manifold gauge set and attach it to the low-pressure service port.
Open the valve on the refrigerant canister and allow it to flow into the system until the correct level is reached (refer to manufacturer specifications).

3. Replace Cabin Air Filter

Tools Required: Flathead screwdriver or trim removal tool.
Locate the cabin air filter access panel (usually under the glove compartment).
Remove the screws or clips securing the panel and take out the old filter.
Insert the new cabin air filter in the correct orientation (check for airflow direction) and secure the access panel back in place.

4. Inspect and Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, AC compressor oil (if applicable).
Remove the serpentine belt from the AC compressor by loosening the tensioner.
Disconnect any electrical connectors and refrigerant lines from the compressor.
Unbolt the AC compressor from its mounting bracket and remove it from the vehicle.
Install the new compressor by reversing the removal steps and ensuring all bolts are torqued to the manufacturer's specifications.
