Why Don’t Car Rear Windows Open Fully?

When traveling in a car, if you sit in the back seat, you want to get some fresh air or watch. But in most cars, this can be frustrating. Because many cars have rear windows, instead of fully opening like windshields opens halfway. So why?

We’re sure a few reasons come to mind when you think about it. However, the reason why automotive manufacturers design these glasses like this It may not be what you think. Let’s take a look at why the annoying rear windows don’t open all the way.

For safety reasons, you may think that the rear windows are not fully opened.

One of the first ideas that comes to mind is sitting in the back seat. the safety of children or pets has been. However, in some cars, more than half of the rear windows can be opened. Therefore, the remaining small glass leaves a large opening where a child or dog can easily get out. It is not very difficult for a child or a dog to get out of here.

Of course, the height of the children in the age of mischief and our animal friends does not fully reach the open part of the glass As a result, a small precaution is provided. However, this is not the main reason why the windows do not open fully.

Actually, they don’t open, they can’t open.

The rear wheels of the cars are placed closer to the door compared to the front. That’s why the back doors curved towards the bottom You can see what you have. Especially in hatchback model cars. positioned closer to the door This curve is much deeper due to the wheel housing.

Due to the curved design of the doors, the place where the glass can go down is limited. In other words, the glass of the rear doors does not actually open; cannot be opened. That’s why “Isn’t it opening any more?” If you keep pushing by saying, You can break your car window.

As you can see in the photo above; Thanks to the size of the butterfly glass, our little friend can comfortably watch outside through the fully open window. In most cars as butterfly glass can’t save Since there are large curves, a small part of the glass can stay up.

The situation may be slightly different if both of your rear windows do not open equally.

If one of your rear windows opens halfway and the other more than half, this is most likely. you broke the glass it means. Because the pieces of broken glass will get stuck inside the door, preventing the glass from falling straight down.

Another common reason is; in the mechanism that allows your glass to go down, that is in the window engine problems that may occur. There are several ways to understand when you encounter situations like this. If your window gets stuck, doesn’t open and makes noises while trying to open your window, you may have a malfunction or broken glass motor. Of course, you may encounter similar situations in cases such as problems in the general electrical parts of your car, crashes after an accident. For this reason, it is best to take an industrial route…
