Have you ever wondered how a rear defogger, also known as a rear defroster, works in a car? It’s a simple yet interesting process that we’re going to explain to you in this blog post.
When your rear windshield gets frosted or fogged, or when there’s snow or ice on it, you can activate your rear defogger to either melt off the snow and ice or defog the window. But how does it work?
If you take a closer look at the rear windshield, you’ll notice that there are lines on the inside that carry an electrical current. When you turn on the rear defroster button, it sends a small electrical current through these lines to heat them up. This reaction causes the windshield to heat up enough to either defog or defrost it.
There are no ducts on the rear of the car, unlike the front, so the defroster works differently. It’s the reaction of the electricity on the windshield that causes the heat, not the electricity itself.
The rear defogger button is usually located somewhere on the dashboard, and when you push it, it illuminates. Electrical current then flows through the lines on the rear windshield, heating it up enough to melt any ice or snow and defog the window.
It’s important to note that in most cars, the rear defogger or defroster automatically shuts off after a certain amount of time to prevent the rear windshield from shattering. Leaving it on for an extended period can cause this to happen.
In conclusion, the rear defogger is a simple yet effective way to defrost or defog the rear windshield of a car. It uses electricity to create a reaction among the rear window, which heats it up enough to serve its purpose. So, the next time you activate your rear defogger, you’ll know how it works!
