Rear Window Heating Element — Removal and Installation (Nissan Terrano 1)

1. The thermocouple consists of a set of horizontal wires embedded in the glass at the forming stage.

2. Minor damage to the wires can be repaired independently; there is no need to remove the glass.

3. To check the operation of the rear window defroster, start the engine and turn on the defroster.

4. Connect one of the test lamp wires to ground and touch the heater wire with the other wire.

5. Move the wire along the wire from right to left - the brightness of the lamp should increase. If the brightness of the lamp is the same at both ends of the wire of the thermoelement, then you should check the connection of the heater to the ground. All wires should be checked in at least two places.

6. To repair the heater you will need a special conductive paste with silver powder (available for sale).

7. Turn off the heater and wait until it cools down.

8. Lightly polish the damaged area with a soft steel wool pad, wipe with alcohol.

9. Apply pieces of adhesive tape to both sides of the damaged area so that the gap between the pieces exactly matches the wire route in the damaged area.

10. Dip a poster pen into the paste and draw a line along the gap between the pieces of tape so that the strip of paste slightly overlaps the damaged area.

11. Carefully remove the pieces of tape and dry the applied track with an air soldering iron at a temperature of 250-350°C for 1-2 minutes from a distance of 2-3 cm from the glass.

12. If necessary, restore the color of the damaged area with iodine tincture. The restored heater can be turned on after at least 24 hours.
