How Often Do I Need Electrical System Service?

In general, your vehicle owner's manual will guide you as to how often you should have your electrical system checked and serviced. Keeping up with your car's maintenance schedule helps to ensure that minor problems are detected and repaired before they become major issues that will cost you a lot of money to fix.

At Greulich's, all of our locations in Phoenix are stocked with a full line of manufacturer-certified tools that can accurately diagnose and repair problems with any of these components. In fact, the quality of the tools, scanners and other diagnostic equipment used by our certified electrical technicians is equal to or better than those used in your local dealership's service department.
