Sub-steps:
- Connect the refrigerant gauge to the low-pressure service port.
- Compare pressure readings to manufacturer specifications.
- If low, proceed to recharge the system.
Tools Required: Refrigerant gauge, refrigerant (R-134a or R-1234yf based on vehicle specification).

3. Recharge the AC System

Sub-steps:
- Locate the low-pressure service port.
- Attach the refrigerant can to the gauge and open the valve slowly.
- Monitor the pressure gauge as the refrigerant is added.
- Disconnect the gauge once the proper level is achieved.
Tools Required: Refrigerant can, refrigerant gauge.
Safety Warnings: Wear gloves and goggles while handling refrigerant.

4. Inspect and Replace the Cabin Air Filter

Sub-steps:
- Locate the cabin air filter housing (usually behind the glove compartment).
- Remove the glove compartment to access the filter.
- Take out the old filter and replace it with a new one.
