Common causes for the check engine light include a loose gas cap, faulty oxygen sensor, malfunctioning catalytic converter, or issues with the mass airflow sensor. A diagnostic scan tool can provide specific error codes to identify the problem.
Start by checking the AC fuse and relay. Ensure the AC belt is in good condition and properly tensioned. Verify the refrigerant level is adequate. If the issue persists, it could be a faulty compressor, condenser, or electrical problem, requiring professional diagnosis.
