1. Run engine at 2,000 r/min. Check heater element with
battery at full.
2. Turn ON rear window defogger switch. Measure heater
element voltage with circuit tester at rear window glass
centre A.
Condition is good if it indicates about 6V.
3. If 12 V is indicated at A, there is a break in the negative
terminals from A.
Move test bar slowly to negative terminal to detect where
voltage changes suddenly (0V).
4. If 0 V is indicated at A, there is a break in the positive
terminals from A. Defect where the voltage changes
suddenly (12 V) in the same method described above.
