All things auto ac repair
Do not put off a visit to your favorite repair shop if your check engine light suddenly goes on. Your check engine light can go on for reasons as minor as a loose gas cap or as major as a malfunctioning engine. Usually a check engine light indicates that your cars onboard diagnostics check has discovered an improperly working component somewhere that could permanently damage your system if left unrepaired. Ignore it at your peril. In late model cars, the check engine light will behave differently depending on the seriousness of the problem.
