Cadillac Escalade Brake Light Switch

Top Reasons Why Your Cadillac Escalade Brake Light Switch Failed

Because your Cadillac Escalade break light switch is built to last for the life of your car, this component is almost always taken for granted. However, several years of use can still cause your brake light switch to break down. To avoid safety problems caused by a faulty brake light switch, take note of these common causes and symptoms of brake light switch failure:

Non-operational brake lights

If all your brake lights are not working, you might have a burnt brake light switch. After several years of turning your brake lights on and off, some of the electrical contacts in your brake like switch may burn out or become covered in soot. Try checking for continuity between the terminals of your brake light switch once the switch is released. If there is no continuity when your switch is released, then you have to get a replacement for your defective brake light switch.

Brake lights won't go off

When your brake lights stay on long after you let go of your brake pedal, then you definitely have a sticky brake light switch. A probable cause of a sticky brake light switch is the buildup of dust and other debris around the switch. In other cases, the brake light switch might not be properly adjusted. A brake light switch that is out-of-adjustment doesn't touch the contact pad that signals the brake lights to turn off. In both cases, the brake light switch might not have to be replaced at all since a simple cleaning or adjustment procedure can take care of the problem. However, if the sticky switch is cause by old age, the brake light switch will probably have to be replaced.

Intermittently working brake lights

Loose electrical connections and worn-out or damaged wires are among the most common culprits behind an intermittently working brake light switch. If your brake lights sometimes work and sometimes don't, then you might want to examine your electrical connections to see if they are firmly attached to your brake light switch and if they are showing any physical signs of damage.

Other troubleshooting techniques

If you have just replaced your brake light switch but your brake light problems didn't go away, recheck your installation. Take note that you also have to adjust your new brake light switch for pedal travel.

  • Keeping Your Cadillac Escalade Brake Light Switch in Good Working Condition 27 February 2013

    Your Cadillac Escalade brake light switch doesn't require too much maintenance, but checking up on this component on a regular basis can save you from the dangers of faulty brake lights. Keep your brake light switch in perfect form with these helpful tips:


    Habitually check your brake light switch for proper voltage.


    Using a voltmeter or multimeter, check for continuity between the terminals of your brake light switch. Make sure that you have 12 volts going in and out of your brake light switch and that there is no continuity when the switch is fully depressed. If your brake light switch fails to meet any of these conditions, then you should get a replacement.


    Clean your brake light switch from time to time.


    Since dirt and grime can build up in and around your brake light switch, it would be a good idea to clean this component about once a year. Use a soft cloth to wipe the electrical contacts and remove any soot, dust, or rust that might cause a sticky brake light switch. You can also use an electrical contact spray cleaner for a more thorough job.


    Visually inspect your brake light switch for signs of damage.


    Examine your brake light switch for any loose electrical connections, damaged wires, broken contact pads, and other cracked components. Replace any defective part as necessary.


    Regularly check the fuse as well.


    More often than not, what you suspect is a case of a bad brake light is actually an issue with your fuse. An overloaded fuse has the tendency to melt and fail to provide power to your switch. Make sure to include this fuse as part of your routine maintenance. Don't forget to check on it when you are trying to find out the culprit behind your faulty brake lights as well.


    Make sure that your brake light switch is properly adjusted.


    Your brake light switch can become improperly adjusted over time and cause your brake lights to remain lit even if the brake pedal is released. To avoid this issue, make sure that you regularly check if your brake light switch and contact pads are still in their proper positions. Otherwise, make the necessary adjustments.
