Auto ac repair What experts say
Ignore it at your peril. In late model cars, the check engine light behaves differently depending on the severity of the problem. A blinking or red check engine light indicates an issue so critical that immediate attention is warranted. A steadily illuminated check engine light indicates a non emergency that should be checked out as soon as possible. Whatever you do, do not take your car to an auto parts store when the check engine light goes on.
