Checking the glass of the tailgate
If during operation it was noticed that one of the grid lines did not work, you can find the gap by following these steps. If none of the grid lines work, a full system diagnostic should be performed before starting repairs.
1. Set the ignition to the ON position.
2. Turn on the heated tailgate glass.
3. From inside the car, connect a voltmeter to each end of the grid line. The voltmeter will show the voltage supplied by the battery if the grid line is open.
Note: Care should be taken when touching the voltmeter contacts to the grid line. If the contacts are applied roughly, the mesh can be scratched, resulting in a broken circuit.
4. If the grid line is open, move the voltmeter leads to one side of the line and repeat the test closer to the other side of the window. Continue checking, each time bringing the voltmeter contacts closer to the side of the window opposite to the one from which the measurements were started. The grid line break point is where the voltmeter starts showing 0 instead of battery voltage.
5. Use a marker chalk to clearly mark the break point on the rear window. The glass should be marked, not the grid line itself, and the mark should be far enough away that it can be removed without ruining the fix.
6. Repair a break in the grid line with a grid line repair kit. See «Repair of lines of a grid of heating of glass of a back folding door» in this section.
Heated front window does not work, heated exterior mirrors work normally.
