         1) Start and run engine at 2000 RPM. Ensure battery is fully

charged. Turn defogger switch to ON position. Using a voltmeter, check

voltage at center section of each defogger grid filament.

         2) If voltage is about 6 volts, grid filament is okay. If

voltage is about 12 volts, an open is present in negative circuit.

Move probe slowly toward negative terminal to determine location of

open circuit.

         3) If voltage is zero volts, an open is present in positive

circuit. Move probe slowly toward positive terminal to determine

location of open circuit. Repair grid as necessary. See

GRID FILAMENT REPAIR under ON-VEHICLE SERVICE.
