Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Recharge Refrigerant

Locate the AC service ports: Find the low-pressure and high-pressure service ports on the AC system.
Connect the refrigerant can: Attach the refrigerant can to the low-pressure service port using a manifold gauge set.
Check pressure: Monitor the pressure readings to determine if the system is low on refrigerant.
Recharge as necessary: If low, open the valve on the refrigerant can to add refrigerant until the system reaches the manufacturer-recommended pressure.

3. Inspect and Replace Compressor

Remove the drive belt: Use a socket set to loosen the tensioner and remove the belt from the AC compressor pulley.
Detach the AC compressor: Unplug the electrical connector and remove the mounting bolts using a socket wrench.
Install the new compressor: Position the new compressor, then secure it with mounting bolts and reconnect the electrical connector.

4. Clean or Replace Cabin Air Filter

Access the cabin air filter: Open the glove compartment and locate the filter cover.
Remove the filter: Take out the old filter and inspect it for dirt and debris.
Install new filter: Place the new cabin air filter into the housing, ensuring proper orientation.

5. Test the AC System

Reconnect the battery: Restore power to the vehicle.
Start the engine: Turn on the AC and set it to the coldest setting.
Verify AC operation: Check that cold air is blowing from the vents.
