1. Turn on the defogger switch and use a voltmeter to measure the voltage of each heater line at the glass 

center point. If a voltage of approximately 6V is indicated by the voltmeter, the heater line of the rear 
window is considered satisfactory.

CAUTION: Wrap tin foil around the end of the voltmeter test lead to prevent damaging 

the heater line. Apply finger pressure on the tin foil, moving the tin foil 
along the grid line to check for open circuits.

4. To check for open circuits, slowly move the test lead in the direction that the open circuit seems to exist. 

Try to find a point where a voltage is generated or changes to 0V. The point where the voltage has 
changed is the open-circuit point.
