Chevrolet Trailblazer Brake Light Switch
Troubleshooting Tips for a Chevrolet Trailblazer Brake Light Switch
An immense and incredible SUV-the Chevrolet Trailblazer could turn into a troublesome road monster if its brake lights are not functioning properly. Brake light problems are commonly caused by blown fuses, busted bulbs, or a defective switch. Due to old age and other damaging factors, these parts are prone to wear out. Here we have some simple troubleshooting techniques to know if the culprit behind your problems is a defective Chevrolet Trailblazer brake light switch:
If your Trailblazer's brake lights are not working, but the fuses and the bulbs are all in good condition, then you can test if the brake light switch is causing the problem. It is located near the brake pedal, and it looks like a small case with a pin. Use a test light to check if the switch is working or not. Press the brake pedal down and try the connections using a test light. If they don't lit up, then you have a defective switch. Replace the switch immediately to restore your brake lights.
If you've already release the brake pedal but the switch doesn't release as well, then your switch could be stuck. This happens when the switch is already worn-out due to age or corrosion, or it has accumulated dirt that keeps it from moving. When this happens, you can either clean the switch and get rid of the dirt that is causing it to get stuck, or you can also replace it with a new one to ensure that it will work properly on your brake lights.
Aside from wear and tear, corrosion is one of the usual suspects behind a faulty brake light switch. If you noticed that your switch is already rusty, expect that its efficiency will also be affected. It is usually made up of metallic components and electrical wirings, so you might as well check its corners for rust spots. Do not hesitate to replace a corroded switch because it could lead to worse problems not only with the switch, but with the other components as well.
