Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the engine and disconnect the negative battery terminal for safety.

2. Recharge the AC System

Tools Required: Manifold gauge set, refrigerant can, AC service hose.
Locate the low-pressure service port on the AC system.
Connect the manifold gauge set to the low-pressure port.
Start the engine and turn on the AC to maximum cool setting.
Open the valve on the refrigerant can and allow refrigerant to flow into the system until the proper pressure is reached (refer to the vehicle manual for specifications).
Disconnect the manifold gauge set and replace the service port cap.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, wrench set, AC compressor removal tool.
If the compressor is damaged or not engaging, it must be replaced.
Disconnect the electrical connector from the AC compressor.
Remove the serpentine belt by releasing the tensioner.
Unscrew and remove the mounting bolts of the compressor.
Disconnect the refrigerant lines (ensure the system is evacuated by a professional if needed).
Install the new AC compressor by reversing the removal steps.
Torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Cabin Air Filter

Tools Required: None (optional flathead screwdriver).
Open the glove compartment and remove any contents.
Locate the cabin air filter cover (may require a flathead screwdriver to pry off).
Remove the old cabin air filter and install the new one.
Reassemble the glove compartment.
