Just hook the clip of the light approximately a great ground and also touch the two metal tabs on height of the fuse. Over there is no have to pull the fuse for this.

Now check the brake light switch. If it works, solve the soil wire.

4. Other Wiring Issues

If her S10’s brake light switch watched ok, and there space no brake lights illuminating at all, examine the wiring exploit going from the brake move to the bulbs themselves. There can be an issue with frayed wiring, wiring that has lost the ground, or a short/open situation.

If you have actually the “third” or committed brake irradiate (the one not in her tail lights), examine the harnessafter lock diverge. You understand that it has actually power prior to this allude since the 3rd brake light is still acquiring power.
