Driver's Window

With the ignition switch in RUN or START, voltage is, applied to the coil of the power window relay. The contacts of the power window relay close and voltage is applied through fuse 6 to the driver's power window switch and the power window control unit. When your move the driver's power window switch to UP, voltage is applied to the power window control unit up input. Voltage is then applied through the power window control unit (motor up control) to the driver's power window motor. The motor's ground path is back through the power window control unit. The power window motor drives the window up. When you move the driver's power window switch to DOWN, voltage is applied to the power window motor in the opposite direction. The motor drives the window down.
