1.Run the engine at a speed
of 2,000 r/min to fully charge the battery, and then check
the printed heater. 2.With the defogger switch
turned on, use a multimeter to measure the voltages of each
printed heater at centre point A on the window glass. The
printed heater is okay if 6 V is displayed. 3.If a
voltage of 12 V is indicated at point A, the open circuit
location is between point A and the (-) terminal to find the
point where the voltage changes is the location of the open
circuit. 4.In addition, if a voltage of 0 V is
indicated at point A, the open circuit location is between
point A and the (+) terminal. Use the same procedure
as described above to find the point where the voltage
changed to 12 V.
