Signs Your Vehicle May Require Diagnostic Services

The electrical system of your vehicle is intricate. Keep an eye out for these warning signs to know when it’s time to take your car in for service.

  • The engine isn’t starting: Your car’s ignition system relies on electrical energy supplied by the battery. If you have trouble starting your automobile, check the battery first. 
  • Poor battery performance: A car battery can last between three and seven years, depending on your vehicle and the alternator voltage output. Our shop can test your battery or provide you with a new one if needed.   
  • Fuses blowing out: Fuses can blow, but they’re readily replaced if they do. If they tend to blow frequently, it might be a sign of trouble with your electrical system.
  • Burnt odors: Stop the car immediately if you smell burning plastic. If this happens, it means that either your brakes or electrical system are malfunctioning. 
  • The coolant sensor is failing: The coolant sensor is responsible for maintaining a steady temperature in your car’s cooling system. Please give us a call if the “check engine” warning light appears on your dashboard so that we can do a full inspection and repair.
  • Lights and headlights are malfunctioning: A problem with your electrical system might be the cause of dimming or flickering headlights or lights inside your vehicle. 

Bring your vehicle in right away for diagnostic services in Santa Cruz, CA, if you notice any of the signs. Postponing service could be dangerous or lead to further electrical damage to your vehicle.
