Power Window System

Main switch (master switch) on driver's door controls all windows. A sub-switch on passenger's door operates only the passenger side window. A permanent magnet motor moves each power window up and down. The direction the motor turns depends on the polarity of the supply voltage. The control switches control the supply voltage polarity. With the ignition switch in the ON position, voltage is applied to a Power Windows Circuit 30-amp fuse in the fuse box. Power then travels to the master switch in the driver's door armrest and then to the passenger's sub-switch.
