Ford Ranger Third Brake Light Not Working Common Causes

Ford Ranger Third Brake Light Not Working Common Causes

If your Ford Ranger third brake light is not working, many potential culprits could be behind this problem. Below, we take a look at the most common causes of this problem.

Bad bulb

Probably the most common cause for the 3rd brake light on your ford ranger not to come on is a blown bulb. The bulb is usually on the same circuit as the primary brake lights.

If the normal brake lights are working but the 3rd brake light is not, its bulb is probably burned out.

Therefore, the first place to check is whether your bulb has burned out. If the filament inside appears broken or the bulb appears blackened, simply replace it with a new one.

Bad wiring

If the bulb is okay, then you may have a wiring issue causing the brake light to malfunction. Check the wiring that leads to the third brake light for signs of physical damage, e.g. fraying.

Does the cable have any visible cuts, signs of wear, or exposed wires? In case of any damages, be sure to repair/replace the wire as necessary.

Loose or corroded connections

Any bad connection (loose or corroded connections) for the third brake light can also cause the brake light to stop working.

Closely examine all the connections and ensure they’re secure and corrosion-free. You may also consider cleaning all the contacts and then reconnecting them.

Blown fuse or relay

Another reason why the brake light is not working may be due to a blown fuse or a bad relay related to the third brake light.

In case you find a blown fuse, simply replace it with a new one that has the same rating as the old one. If the relay is faulty, you will need to replace it.

The fuse for the third brake light is separate from that of the lower brake lights. If you’re not sure which fuse to check, consult your user manual

What To Do If Your Ford Ranger Third Brake Light Is Not Working

If your Ford Ranger third brake light isn’t working, there are a few steps you can take to find out what is causing the light to fail.

  • The first step is to check if the bulb is blown. If the bulb has burned out, buy a replacement bulb that works for your Ford Ranger model and test if it’s working.
  • Try swapping the current bulb with a new one and see if it works. Even if the bulb doesn’t look blown, it could still be burned out.
  • If the light doesn’t come on, next you’d want to inspect the wiring and connections leading to the 3rd brake light. They should all be secure and free from corrosion. Clean and reconnect them as necessary.
  • Next, you should inspect if the fuse or relay related to your center high mount stop lamp are faulty and replace them with new ones.
  • Don’t forget to check all the wires connecting to the brake light for any signs of fraying or damage and replace them as necessary.

If you have tried all the above problems and none of them seems to solve your problem, take your car to a mechanic for expert diagnosis and repair.

Where Is The Fuse For The Brake Lights On A Ford Ranger?

If you suspect a blown fuse for brake lights could be the reason behind the brake light not coming on, you may want to look at the fuses to confirm.
