Filament Inspection
1. Switch the ignition ON (engine off).
2. Turn the rear window defroster switch on.
CAUTION:
Directly touching the rear window defroster filament with the lead of the
tester could damage it. Wrap aluminum foil around the end of the lead and inspect
the filament by touching it ...
