LH Front Window Switch Operation

When the ignition switch is in the RUN position, voltage is applied to the LF window switch through the PWR WDO Circuit Breaker and to circuit 143. When any of the up switches in the LF window switch are operated, voltage is applied to the window regulator motor. The window regulator motor is grounded through the down contact in the LF window switch. The motor runs to drive the window up. When any of the down switches in the LF window switch are operated, voltage is applied to the window regulator motor in the opposite direction. The window regulator motor is grounded through the up contact in the LF window switch. The motor runs to drive the window down.
