Check Voltage At The Grid Filament
  

Measure the voltage at the center of each heated back window grid filament. The voltages should be approximately 5 volts at the center of each filament. If the heated back window grid does not operate as specified, repair the filament(s) in question; refer to Heated Window Grid Wire Repair. Otherwise, return to the pinpoint test. See: Pinpoint Tests
