Rear glass heating is a very useful feature that many modern cars are equipped with. However, sometimes this function does not work correctly, delivering the car owners a lot of inconvenience.
Mazda's 6 2nd generation owners often complain that the top of the rear window heating does not work. In fact, the top strands placed on the back of Mazda 6 II are not heaters and therefore should not perform such a function. A number of top threads in the back of Mazda 6 are the antenna of the regular audio system.
