Examination
3. To check the operation of the heater, start the engine and turn on the heater.
4. Connect one wire of the test lamp to ground and carefully touch each track with the other wire.
5. The brightness of the lamp should increase as the wire moves along the element (see illustration). If the lamp is equally bright at both ends of the line, check the ground wire contact. Each track should be checked in at least two places.
17.5a. When the rear window heating is working properly, the brightness of the lamp should change |
17.5b. When the heating threads are checked from the "ground" side, the lamp will light: 1 - No light; 2 - Damaged mesh; 3 - Full brightness; 4 - "Mass"; 5 - "+"; 6 - Full heat |
Repair

11/17 To repair damaged tracks, stick a strip of tape on both sides of the mesh, then apply the conductive compound using a small wooden stick or spatula: 1 - Repair material; 2 - Two strips of tape; 3 - Wooden spatula
12. Carefully remove the tape and direct the hot air stream directly onto the repaired area. It is recommended to use a hair dryer that provides a temperature of 260-375°C. Hold the hair dryer one inch away from the glass for two minutes.
