Solution

1. Preparation

Gather tools and safety equipment.
Tools Required: Socket set, refrigerant gauge, OBD-II scanner, safety goggles, gloves.
Disconnect the vehicle's battery to ensure safety while working.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter housing, usually found behind the glove box.
Remove the glove box and access the filter housing.
Remove the old cabin air filter and inspect it for dirt and blockages.
Replace with a new cabin air filter, ensuring proper orientation.

3. Refill Refrigerant

Connect the refrigerant gauge to the low-pressure service port.
Check the refrigerant level; it should be within the manufacturer's specifications.
If low, add the appropriate type of refrigerant (usually R-134a or R-1234yf depending on the model).
Follow the manufacturer’s guidelines for the correct amount and method of charging.

4. Inspect and Test the AC Compressor

Reconnect the battery and turn the AC to the maximum setting.
Listen for the AC compressor to engage; if it does not, further investigation is needed.
If the compressor is not functioning, replace it according to the manufacturer's specifications.
To replace, detach any electrical connectors, remove mounting bolts, and install the new compressor.

5. Clear Obstructions in the AC Condenser

Inspect the AC condenser for any debris or obstructions.
Clean the condenser with water or compressed air to ensure optimal airflow.
Ensure no damage is present on the condenser fins.
