Normal Operation

Under normal operation, when the driver window control switch is commanding the passenger window DOWN, voltage is sent to the passenger window control switch through circuit (T/LB) and ground through circuit (W/Y). When UP is commanded, voltage and ground from the driver window control switch is reversed. Voltage is supplied to the passenger window control switch through circuit (LB/B). Ground is provided by the driver window control switch (at rest) through circuits (W/Y) and (T/LB). When the passenger window control switch commands the passenger window DOWN, voltage is sent to the passenger window control motor through circuit (Y/R) and ground through circuit (R/Y). When UP is commanded, voltage and ground from the passenger window control switch is reversed.
