Repair of rear window heating by own hands

Now absolutely every car is equipped with a heater on the rear window. Visually it looks like thin threads, because of what motorists call them "heater threads". This tool is designed to effectively remove frost from the glass surface, thereby preventing the occurrence of an ice crust on it. If the heater is defective, this will significantly affect the visibility. Hoarfrost can completely cover the surface of the glass, which creates an emergency situation. Therefore, this mechanism should always be in working order. Well, if you need to repair the heating of the rear window, then this article is for you.

First we need to determine the place where these threads were damaged. This can be done with a voltmeter. When the heater is on, the voltage on both wires must be 11 Volts.

Now you need to prepare the necessary tools. In order to qualitatively repair the rear window of the car, we need sulfuric acid, a section of a copper tube with a diameter of 7-8 millimeters, copper sulfate and a strip of cloth measuring 30x0.5 millimeters.

The end of the tube is wound with a strip of tissue. It takes only half of its width to wind it to get a kind of brush. Now put the threads on the fabric in such a way that the latter does not unwind. At the next stage, the repair of the rear window heating terminal is accompanied by the manufacture of an electrolyte. To do this, take a glass, fill half of its volume with water, then pour a few teaspoons of copper sulphate. The resulting mixture is thoroughly stirred and a solution of concentrated sulfuric acid (per 100 milliliters, about ½ teaspoon) is added.

Now connect the terminals to the ground; The "+" battery is connected to the handset. The plus electrode is dipped into the solution and processed by them the place of rupture of the filaments. The voltage that will pass through the current transfers the copper ion, so that the threads are heated. If the scale of failure is small, then after 5 minutes the repair of rear window heating will be completed, and the device will work fully. If this did not happen, then the threads were seriously damaged. In this case, we take the soldering iron in hand and process the areas with the solution applied. At this stage we need to solder a jumper from a thin wire. Also do not forget that the solution with sulfuric acid is very dangerous for the fabric on clothes, so observe the precautionary measures.

If you are not confident in your abilities, you can try to repair the heating of the rear window in a different, faster and easier way. For this we will need a Done Deal repair kit. It is specifically designed for such works. The glue will form a conductive layer on the glass surface, which has the same electrical resistance as the filaments themselves.

Whatever method of repair you use, still in both cases, the rear window heater will be repaired. The difference is only in time and cost of work.
