      • Is the voltage greater than 11 volts when the Left Hand (LH) front window control switch is pressed; and 0 volt when released? 
      • Yes:  GO to step  8 .
      • No:  If voltage was less than 11 volts when the switch was pressed, GO to step 6 .

        If voltage was greater than 0 volt when the switch was released, GO to step  7 .

  6. CHECK FOR AN OPEN BETWEEN THE SUSPECT WINDOW CONTROL SWITCH AND THE Left Hand (LH) FRONT WINDOW CONTROL SWITCH
    1. Ignition OFF.
    2. Disconnect: Left Hand (LH) Front Window Control Switch.
