Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Recharge Refrigerant

Tools Required: AC manifold gauge set, refrigerant canister.
Check the refrigerant level on the gauge; if low, proceed to recharge.
Connect the low-pressure side of the manifold gauge to the service port.
Start the engine and turn the AC to maximum cooling.
Open the refrigerant canister valve slowly and monitor the gauge until the recommended pressure is reached (typically 30-40 psi on the low side, depending on ambient temperature).
Disconnect the service port and recheck for leaks.

3. Inspect AC Compressor

Tools Required: Socket set, torque wrench.
Locate the AC compressor and visually inspect it for any signs of damage or leaks.
Start the engine and turn on the AC; observe if the compressor clutch engages.
If the compressor does not engage, check the electrical connections and fuses.
If it engages but makes unusual noises, the compressor may need replacement.

4. Replace Cabin Air Filter (if necessary)

Tools Required: Screwdriver or trim removal tool.
Open the glove compartment and locate the cabin air filter housing.
Remove the cover and take out the old filter.
Install the new cabin air filter, ensuring it is oriented correctly.
Reattach the cover and secure the glove compartment.

5. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all tools and loose items are removed from the engine bay.
