Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Recharge AC System

Tools Required: Manifold gauge set, refrigerant canister
Connect the low-pressure side of the manifold gauge to the AC system service port.
Open the valve on the refrigerant canister and allow refrigerant to enter the system until the gauge reads the manufacturer's specified pressure.
Disconnect the manifold gauge and secure the service port cap.

3. Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, refrigerant recovery machine
Remove the front grille to access the AC compressor.
Disconnect electrical connectors and hoses from the compressor.
Unbolt the compressor from its mounting bracket and remove it from the engine bay.
Install the new compressor and torque bolts to manufacturer's specifications.
Reconnect hoses and electrical connectors securely.

4. Replace Cabin Air Filter (if necessary)

Tools Required: None
Locate the cabin air filter compartment, usually behind the glove box.
Remove the glove box (if necessary) to access the filter.
Remove the old filter and install the new one, ensuring it is oriented correctly.

5. Test the AC System

Reconnect the battery and start the engine.
Turn on the AC to the maximum setting and check if cold air is blowing from the vents.
Monitor for any unusual sounds or leaks.
