Almost all cars today are equipped with heated rear windows. Sometimes it happens that this heating stops working. To bring it into working order, it is better to contact a specialist workshop. But you can make repairs yourself.
Instructions
Step 1
Determine the cause of the heating failure. Inspect carefully all the heater wires located on the rear window - perhaps the reason is a break in one or more of them. Broken threads are usually visible to the naked eye.
- Find the places of the cliffs.
- Take the conductive adhesive from the rear window defroster repair kit and the stencil.
- Apply stencil glue to the break in the heater filament.
- Check that the heater is working properly.
Step 2
If there is no repair kit, take DD6590 glue (in the form of a syringe with an activator) + 0.5 ml (in the form of a syringe with a silver compound), a wooden applicator, a napkin soaked in alcohol. This is a DONE DEAL kit designed specifically for repairing the rear window defogger threads and its contacts. The glue forms a conductive layer on the glass with the same electrical resistance as the heater filaments. Provides consistent results. It can be used both in auto repair shops and independently. Packaging DD6590 allows it to be reused and repaired up to 20 cm of heating filaments.
Step 3
Check the integrity and cleanliness of the contacts on the connectors of the electric heater (they may be oxidized). To do this, measure the supply voltage using an auto tester or volt-ohm meter directly on the contact glued to the glass: if the voltage is less than 11 V, clean the contact. Check the integrity of the electrical wiring (in case you did not find any breaks in the threads of the electric heater on the glass). To do this, use a voltmeter or auto-tester: on those wires that supply current to the terminals, the voltage with the heater turned on must be at least 11 V. Check the presence and serviceability of the fuse. If the fuse is blown, replace it with a good one. Strip the contacts in the place of its installation before installing a new fuse.
