the following table.
If defogger wire open is found, go to next step.
Defogger wire voltage
4) Touch voltmeter negative (–) lead to defogger wire ground terminal end (1).
5) Touch voltmeter positive (+) lead with a foil strip to defogger wire power source terminal end (2), then
move it along wire to defogger wire ground terminal
end (1).
The place where voltmeter fluctuates from 10 – 12 V
to 0 – 1 V is where there is open.
If found defective, repair defogger wire referring to
“Rear End Door Window Defogger Wire Repair”.
