Why Volkswagen Right Brake Light Not Working

Burnt-out Bulb

The most common cause of a non-working brake light is a burnt-out bulb. To check if this is the case, open the trunk and look at the brake light housing. If the bulb is blackened or cracked, it needs to be replaced.

Loose or corroded wiring

Another common cause of a non-working brake light is a loose or corroded wire. To check for this, follow the wiring harness from the brake light switch to the bulb. Make sure that all of the connections are tight and that there is no corrosion.

Faulty brake light switch

The brake light switch is a small switch that is located under the dashboard. When you press the brake pedal, the switch closes and sends a signal to the brake lights to turn on. If the switch is faulty, it may not be able to close properly and the brake lights will not turn on.

Faulty brake light fuse

The brake light fuse is a small fuse that is located in the fuse box. If the fuse is blown, the brake lights will not work. To check the fuse, remove it from the fuse box and look at it. If the fuse is blackened or melted, it needs to be replaced.

Problem with the brake light control module

The brake light control module is a small computer that controls the operation of the brake lights. If the module is faulty, it may not be able to send the signal to the brake lights to turn on.

Other causes

There are a few other possible causes of a non-working brake light, such as a faulty brake pedal switch or a problem with the brake light relay. If you have checked all of the above causes and the brake light still does not work, it is best to take your vehicle to a qualified mechanic for diagnosis.
