Window Motors

Each door module supplies battery voltage and ground, through window motor drive circuits, to appropriate window motor. Window motors are reversible. Direction window moves depends on which motor drive circuit battery voltage is applied to, and which motor drive circuit ground is applied to. To move window to up direction, module applies battery voltage to window motor up drive circuit, and ground to window motor down drive circuit. When a window movement in the opposite direction is needed, door module reverses polarity and supplies power and ground to opposite circuits moving window in reverse direction.
