If you are experiencing an electrical problem such as an issue with lights, check engine light, power windows, or your car battery, we encourage you to bring your vehicle into our Houston auto repair shop for testing and diagnosis. We work on all makes and models of vehicles and our mechanics are ASE certified who are highly skilled when it comes to diagnosing and repairing electrical faults.

When you bring your vehicle into our mechanic shop with any of these issues, our professionals will perform a battery and charging system test to truly understand the cause of your vehicle’s electrical problems.
