Friend should have the ability to see the brake lamp illuminating the door. If even one that them come on, you recognize that the brake light fuse isn’t blown. We’ll go into more depth on that below.

Driving without the brake lights functioning is simply as unsafe together if her S10’s brake lights were stuck on.

1. Check the Fuse

If nobody of the brake lights space working, we room going to monitor the circuit from the fuse box earlier to the brake pedal. In ~ some allude the strength is not getting from allude A to allude B. We just have to uncover where the is.

Please keep in mind that tail lights have the right to work also if the brake lights are shed out. That is entirely possible that all the brake lights melted out at the very same time.

Even if the looks fine, if you have an additional fuse that the same amperage, swap it anyway. What works better is utilizing a simple electrical check light to recognize if the circuit works. Wal-Mart and any parts store will store them in stock, normally at $10 or less.

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. It have to be “hot” on both sides. If the is not, change the fuse. If that blows much more than once, it’s likely that your S10’s wiring harness has been damaged ~ above the method to the brake lights. Make sure to put the very same size fuse earlier in

2. Examine your S10’s Brake light Switch

Ok, now we’ve confirmed that there is power going come the brake irradiate circuit, it’s time to number out where in the course from the fuse crate to the brake lights the power is lost. The most usual location is thebrake light switch. The good news is they are inexpensive and also easy come replace.

Your S10’s brake light switch is under the brake pedal. It always should have actually power to run to it, even if the crucial is off. Us need certainly need a test light in ~ this point. The video below shows exactly how to perform this.

He has actually the brake irradiate switch out of the vehicle, which makes it way easier come see. You execute not should do this.

You may need to consult your hand-operated to identify which one is which. But, as a general rule, the cruise regulate switch will certainly not have actually power going to it as soon as the key is off prefer the brake irradiate switch does.

3. Examine for a bad Ground

If there is a soil wire to run to the brake irradiate switch, make sure that that is secured tightly and corrosion free. If friend can’t discover the ground wire at all, run a jumper cable to substitute because that the floor wire.

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.
