Auto Diagnostics & Check Engine Light Service in Gurnee, IL
Modern vehicles are rolling computers with dozens of sensors and control modules. When something goes wrong, your car’s computer stores diagnostic trouble codes – but those codes are just the starting point.
At McClure’s Garage, we don’t just read codes and guess. Our ASE-certified technicians use advanced diagnostic equipment and decades of experience to trace problems to their source.
