Normal Operation
Front Passenger Window When the key is in the START or RUN position, voltage is supplied from the central junction box (CJB) to the front passenger window control switch on circuit 15-AJ18 (GN/WH). Circuit 15-AJ18 (GN/WH) illuminates the switch light emitting diode (LED) and provides voltage for window operation from the front passenger window control switch. Switch illumination is grounded through circuit 31-LH31 (BK). When the front passenger window control switch is moved to the window down position, voltage is supplied to the window motor through circuit 32-AJ17 (WH/VT). The window motor is grounded by circuit 33-AJ17 (YE/VT), through the front passenger window control switch to circuit 33-AJ18 (YE/VT) which is connected to ground by the driver window control switch. When the front passenger window control switch is moved to the window up position, voltage is supplied to the window motor through circuit 33-AJ17 (YE/VT). The window motor is grounded by circuit 32-AJ17 (WH/VT) through the front passenger window control switch to circuit 32-AJ18 (WH/VT) which is connected to ground through the driver window control switch.

LH Rear Passenger Window When the key is in the START or RUN position, voltage is supplied from the CJB to the driver window control switch through circuit 15-AJ10 (GN/OG). If the driver window control switch is in the window LOCK position the circuit is opened and the rear windows will not operate from their respective window control switches. Voltage is supplied to the LH rear window control switch through circuit 15S-AJ2 (GN/BU), and 15S-AJ14 (GN/RD) illuminating the switch light emitting diode (LED) and providing voltage for switch operation. The LH rear passenger window control switch is grounded through circuit 31-LH36 (BK). When the LH rear window control switch is moved to the window down position, voltage is supplied to the window motor through circuit 32-AJ31 (WH/RD). The window motor is grounded by circuit 33-AJ31 (YE/RD) through the LH rear passenger window control switch to circuit 33-AJ32 (YE/BU) which is connected to ground by the driver window control switch. When the LH rear window control switch is moved to the window up position, voltage is supplied to the window motor through circuit 33-AJ31 (YE/RD). The window motor is grounded by circuit 32-AJ31 (WH/RD) through the LH rear passenger window control switch to circuit 32-AJ32 (WH/BU) which is connected to ground by the driver window control switch. When operating the LH rear passenger window to the down position from the driver window control switch, voltage is supplied to the window motor on circuit 32-AJ14 (WH/BU) through the LH rear passenger window control switch and circuit 32-AJ31 (WH/RD). The motor is grounded by circuit 33-AJ31 (YE/RD) through the LH rear passenger window control switch to circuit 33-AJ32 (YE/BU) which is connected to ground through the driver window control switch. When operating the LH rear passenger window to the up position from the driver window control switch, voltage is supplied to the window motor on circuit 33-AJ14 (YE/BU) through the LH rear passenger window control switch and circuit 33-AJ31 (YE/RD). The motor is grounded by circuit 32-AJ31 (WH/RD) through the LH rear passenger window control switch to circuit 32-AJ32 (WH/BU) which is connected to ground through the driver window control switch.

RH Rear Passenger Window When the key is in the START or RUN position, voltage is supplied from the CJB to the driver window control switch through circuit 15-AJ10 (GN/OG). If the driver window control switch is in the window LOCK position the circuit is opened and the rear windows will not operate from their respective window control switches. Voltage is supplied to the RH rear window control switch through circuit 15S-AJ2 (GN/BU), and 15S-AJ24 (GN/YE) illuminating the switch light emitting diode (LED) and providing voltage for switch operation. The RH rear passenger window control switch is grounded through circuit 31-LH36 (BK). When the RH rear window control switch is moved to the window down position, voltage is supplied to the window motor through circuit 32-AJ31 (WH/RD). The window motor is grounded by circuit 33-AJ31 (YE/RD) through the RH rear passenger window control switch to circuit 33-AJ32 (YE/BU) which is connected to ground by the driver window control switch. When the RH rear window control switch is moved to the window up position, voltage is supplied to the window motor through circuit 33-AJ31 (YE/RD). The window motor is grounded by circuit 32-AJ31 (WH/RD) through the RH rear passenger window control switch to circuit 32-AJ32 (WH/BU) which is connected to ground by the driver window control switch. When operating the RH rear passenger window to the down position from the driver window control switch, voltage is supplied to the window motor on circuit 32-AJ24 (WH) through the RH rear passenger window control switch and circuit 32-AJ31 (WH/RD). The motor is grounded by circuit 33-AJ31 (YE/RD) through the RH rear passenger window control switch to circuit 33-AJ32 (YE/BU) which is connected to ground through the driver window control switch. When operating the RH rear passenger window to the up position from the driver window control switch, voltage is supplied to the window motor on circuit 33-AJ24 (YE) through the RH rear passenger window control switch and circuit 33-AJ31 (YE/RD). The motor is grounded by circuit 32-AJ31 (WH/RD) through the RH rear passenger window control switch to circuit 32-AJ32 (WH/BU) which is connected to ground through the driver window control switch.
