Expert troubleshooting and repair for all vehicle electrical issues
Modern vehicles rely on complex electrical systems to control everything from engine performance and safety features to comfort and convenience systems. When electrical problems occur, they can be challenging to diagnose due to the interconnected nature of these systems and the hundreds of electrical components in today's vehicles.
At D&H Auto Works, our certified technicians specialize in electrical system diagnosis and repair. We use advanced diagnostic equipment and follow systematic troubleshooting procedures to identify the root cause of electrical issues, rather than simply replacing parts based on guesswork.
Our comprehensive approach ensures that we accurately diagnose and effectively repair electrical problems, saving you time and money while getting your vehicle back on the road quickly and safely.
Our electrical system diagnosis and repair services cover all electrical components in your vehicle, including:
Our electrical system diagnosis process begins with a conversation about the symptoms you've experienced, such as warning lights, intermittent issues, or specific components that aren't functioning properly. This helps our technicians focus their investigation on the most likely causes.
Next, we'll perform a comprehensive inspection of the relevant electrical systems, starting with basic checks of the battery, alternator, and starter if the issue is related to starting or charging. For more complex issues, we'll use specialized diagnostic equipment to test circuits, measure voltage drops, check for parasitic draws, and identify faulty components.
For computer-related issues, we'll connect our diagnostic scanners to retrieve error codes and monitor real-time data from sensors and control modules. This allows us to identify communication problems, sensor failures, or control unit malfunctions.
Once we've identified the problem, we'll provide you with a detailed explanation of the issue and a transparent estimate for the necessary repairs. Electrical diagnostics can take anywhere from 30 minutes to several hours, depending on the complexity of the issue and whether it's intermittent in nature.
After completing any repairs, we'll verify that the issue has been fully resolved through comprehensive testing of the affected systems.

Two other shops couldn't figure it out, but the technicians at D&H Auto Works were persistent and methodical in their diagnosis. They found a corroded wire in a hard-to-reach area and fixed it permanently. Their expertise saved me from replacing my car!"
"My car's electrical system was acting strange - power windows would work sometimes, the radio would cut out, and occasionally it wouldn't start. D&H Auto Works diagnosed it as a failing alternator that was causing voltage fluctuations. They replaced it quickly and at a fair price. All electrical systems have been working perfectly ever since!"
