of vehicles back in their windows The available defrost wires are an indispensable tool for many drivers during the winter months. However, as we said, these wires are not on the windshield.

The reason behind this situation is actually quite significant logically It is based on some technical details that you will find. Come on, let’s investigate it together.

First, let’s look at the mechanics of the windshield and rear window.

On rear windows it is usually embedded in the glass. heating wires An electric defrosting system is used. When this system is activated, the wires heat up and the fog or ice on the glass quickly disappears. This method allows the rear window to be removed from the vehicle. weather current This is very useful considering the lack of direct access to their systems.

Warm air from the vehicle’s heater hits the windshields, engine as it gets warmer This is caused by air blowing from the ventilation holes in the windshield. This air is led to the glass and the ice is dissolved.

So why are different systems used in two glasses?

The method on the windshield ensures that the engine is sufficient heat up Given the time required for this slowly It might come. However, integrating heating elements into the windshield, as with the rear windows, would be more expensive and complex because the windshield is larger and requires clear vision without visual interruptions such as wires.

There are also preheated windows available on the market.

Heated windshields are also available on some vehicles, but generally there are more high on recommended models or optional They are available as. These glasses can quickly defog the glass thanks to the network of fine threads in it.

This feature was once an exclusive technology found in vehicles produced by Ford, but now that the patent is expiring, it has spread to a wider audience.

In summary, the rear windows can use a simple and expensive electrical system, while the front windows generally use an air-based system, which is slower due to cost and design requirements. Heated windshields offer a faster alternative, but their use is reduced due to the higher cost.
