THE PRINTED-HEATER LINES CHECK
(1) Run engine at 2,000 rpm. 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
center A.
Condition good if indicating about 6 V.
(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 (0 V).
(4) If 0 V is indicated at A, there is a break in the positive
terminals from A. Detect where the voltage changes
suddenly (12 V) with the same method described.
