If there is a problem, first check the fuse in the fuse box.
If the fuse is good, check the tight fit of the wire tip by turning it left and right on the rear window, if necessary, clean it from corrosion products.
If the rear window heating system still does not function, check the integrity of the supply wires and the functionality of the switch, as well as the switching relay, see item 20.4.
1 - Broken wire; 2 - Sticky tape; 3 - Repair area
If the heating lines are broken, conductive silver varnish helps to restore their connection. To do this, clean the damaged area with thinner or ethyl alcohol.
Cover the torn area on both sides with adhesive tape and apply silver varnish with a small brush.
Leave the varnish to dry at a temperature of about 25°C for 24 hours. You can warm it up with hot air. At a temperature of 130°C the varnish dries in about 30 minutes.
Warning! Do not turn on the rear window heating system until the varnish is completely dry. Do not use gasoline or other solvent to clean the damaged part.
