An experienced motorist differs from a beginner in that he knows a huge number of various tricks that can make life much easier. Take the heated rear window, for example. Many people believe that it can only be used to fight ice. In fact, this is not the case.
Practice shows that the overwhelming majority of motorists remember the rear window heating system only when it comes to extremely cold weather and the need to remove ice from the glass. However, experienced motorists are also well aware of how this whole system can be applied in summer, spring and autumn. The fact is that the "winter" function actually has alternative ways of using it.
First, it is worth recalling that only a steamed turnip is simpler than a rear window heating system in the world. The mechanism works as simply as possible, and therefore flawlessly. A special film is applied to the glass, lined with incandescent filaments. They are powered by electricity. As you might guess, when the system is activated, these threads are heated and contribute to the rapid removal of snow and ice from the glass.
Note: In inexpensive car models, the heating system (as a rule) does not have an automatic shutdown function, and therefore it must be constantly monitored and turned off manually. If this is not done, the filaments will overheat and may even burn out.
Considering the fact that filaments heat up the glass of a car quite strongly, it is not difficult to come up with an alternative way of using them. Thus, heating becomes the best ally for the fight against water, including in rainy weather. Rear window heating will help to significantly improve visibility, and therefore travel safety. It is much more important that the glass can be heated to combat fogging. In order to get rid of condensation, it is necessary to simultaneously turn on the heating of the glass and the air conditioner.
Note: also for the quickest victory over condensation, it is recommended to turn on the air recirculation mode in the passenger compartment.
Finally, it remains to add that, like any other mechanism, the rear window heating system needs to be checked regularly. This is another reason why it should be turned on periodically so as not to get into a difficult situation at the most crucial moment.
