Solution

1. Preparation

• Tools Required: Safety glasses, gloves, OBD-II scanner, refrigerant pressure gauge, multimeter.
• Safety Warnings: Disconnect the battery before working on electrical systems; ensure the engine is off when inspecting components.

2. Recharge Refrigerant

• Step 1: Locate the low-pressure service port on the AC system.
• Step 2: Connect the refrigerant gauge to the low-pressure port.
• Step 3: Add refrigerant according to the manufacturer's specifications (typically R-1234yf for this model).
• Step 4: Monitor the pressure gauge and ensure it falls within the normal operating range (usually around 30-40 psi on low side).

3. Repair or Replace AC Components

• Step 1: If the compressor is not engaging, test the AC clutch with a multimeter to check for continuity.
• Step 2: If there is no continuity, replace the AC compressor or clutch assembly.
• Step 3: If fuses are blown, replace them with the specified amperage fuses.
• Step 4: If the cabin air filter is clogged, remove and replace it with a new one.

4. System Cleaning

• Step 1: Use an appropriate AC system cleaner to eliminate any foul odors and bacteria from the evaporator core.
• Step 2: Introduce the cleaner through the system while running to ensure it circulates properly.
