The first thing to check if you’re experiencing problems with electronics in your car is the fuse that controls the circuit. If you’ve never inspected or replaced a fuse before, it’s simple. Here’s how:

  1. Turn the ignition off (lock).

  2. Make sure all of the accessories are off as well, including your headlights.

  3. Open the fuse box.

  4. The first fuse to check is the large combined fuse in the underhood fuse box.

  5. If you see a blown connector, it needs to be replaced.

  6. Use a Phillips head screwdriver to remove it, and replace it with a new one.

  7. Check all small fuses in the fuse box under the hood, as well as the one under the dash.

  8. Replace any of them that are blown (you’ll see a broken connector inside the fuse).


Always replace a fuse with one of the same rating. Do not replace it with one with a higher rating.
