About Door Switches

When you open your door, your vehicle remains dark and you cannot see what you are doing. If you have a door light switch that is not working properly, things like dome lights and other automatic processes may not work when you open and shut your vehicle doors. A door switch light works by signaling your dome lights when you open your door so that you can easily and safely enter and exit your vehicle when it is dark outside. A door jam switch works in a similar fashion and may be used for things like activating lights or even the alarm system on your car. Since a simple door switch does so much to provide safety and comfort in your vehicle, if one of these goes bad, you want to replace it right away. Make sure you have the make, model, and year of your vehicle when you search for these switches on eBay to ensure you get the right one for your car or truck.
