Owning a car means taking responsibility for its maintenance, and knowing how to handle minor issues yourself can save you time and money. Here’s a detailed guide to fixing common problems like dashboard warning lights, car batteries, and wiper blades. Let’s dive into these simple but essential DIY car repair tips.

Fixing Dashboard Warning Lights

Dashboard warning lights indicate potential issues in your car. Here's how to address the most common ones:

Check and Simple Fixes:

  • Check Engine Light:
    • Ensure the gas cap is tightly closed, as a loose cap can trigger this light.
    • Use an OBD-II scanner (available for $20-$50) to read error codes and look them up online for solutions.
  • Tire Pressure Warning Light:
    • Check tire pressure with a gauge and inflate to the recommended level (usually listed on the driver’s door frame).
  • Battery Warning Light:
    • Inspect battery terminals for corrosion or loose connections. Clean them using a mixture of baking soda and water with a wire brush.

Reminder:

If the light persists after these steps, consult a professional mechanic for a thorough diagnosis.
