What my thoughts say about auto ac repair
A certified repair technician has the knowledge and the access to equipment essential to a proper diagnosis of your problem. Some issues that require proper diagnosis would be sudden illumination of any dashboard warning lights (such as the check engine light), emission failure, engine or transmission performance or steering and ride control malfunction. The diagnosis will include a scan test for stored trouble codes and a systems and components check to eliminate possible causes. Diagnosis and correction can often occur within the same day. Absolutely do not take your car to an auto parts store for a diagnosis when your check engine light goes on.
