When using a car, safety and comfort must come first. One of the components of safe passage in winter is a clean rear window, without fogging and snow crust.
Instructions
Step 1
In frosty weather, if the windows of your car are fogged up or covered with a layer of frost, turn on the heated rear window: this will improve visibility and ensure safety on the road. After turning on the heating, the corresponding indicator should light up, which is located on the dashboard of the car. A couple of minutes after turning on the heating, look at the rear window: it should become cleaner and more transparent, and the snow on the outside of the car will begin to melt. Place your hand on the glass. If the heating is working properly, you should feel warm.
Step 2
If the heating operation indicator shows that operation has started, but the glass is still covered with vapor, check to see if the heated rear window fuse is on. Turn it off if necessary.
Step 3
If the glass is not frozen enough and there is no snow on the surface of the vehicle, use the following methods to check the heated rear window. Sit in the back seat and exhale vigorously through your mouth onto the glass. It should fog up, and immediately begin to clear from the warm heating lines.
Step 4
Stand outside the car and pour some water onto the rear window. A properly working heating will not allow water to freeze on the glass, even in severe frost. If only some of the heating threads are out of order and the glass heats up unevenly, using water it is easy to calculate which strips need to be replaced. Pour water on the glass and see where it is frozen. If you don't have water on hand, try scattering some snow onto the glass.
Step 5
Those who like to rummage in the car and check the health of all contacts can try the following check method. Turn on the heated rear window. If the indicator shows its operation, the relay is working properly, open the heater contacts on one side of the glass and connect them together through a "probe". If the heater is working properly, the current will flow freely through the heating filaments, causing the probe to glow. If the probe does not brighten, the heater filaments are faulty or the contacts are oxidized.
