Solution

1. Preparation

Tools Required: Safety goggles, gloves, manifold gauge set, UV leak detection kit, multimeter.
Safety Warning: Disconnect the battery before servicing electrical components.

2. Check and Recharge Refrigerant

Locate the low-pressure service port on the AC system.
Connect the manifold gauge set to the low-pressure port.
Check the pressure reading; it should be within the manufacturer's specifications.
If refrigerant is low, add the appropriate refrigerant (R-134a or R-1234yf, depending on the model).
Monitor the system while adding refrigerant to avoid overcharging.

3. Inspect and Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Remove the glove compartment by detaching the hinge stops.
Locate the cabin air filter housing and remove the cover.
Take out the old cabin air filter and inspect for dirt and clogs.
Install a new cabin air filter ensuring the airflow direction matches the markings.
Reassemble the glove compartment.

4. Test AC Compressor and Electrical System

Use a multimeter to check the voltage at the AC compressor connector while the AC is turned on.
If no voltage is present, check the AC relay and fuses.
Replace any faulty relays or fuses as necessary.
If voltage is present but the compressor does not engage, replace the compressor.

5. Clean the Condenser

Inspect the condenser for debris obstructing airflow.
Use compressed air or a soft brush to clean the condenser fins.
Ensure that the condenser is free from any physical damage.
