Normal Operation

With the ignition switch in the START or RUN position, voltage is supplied to the driver window control switch from the central junction box (CJB) on circuits 15-AJ1 (GN/BU), 15-LH14 (GN/YE) and 15-AJ7 (GN/BU). Circuit 15-LH14 (GN/YE) is spliced off circuit 15-AJ1 (GN/BU) and provides voltage to the switch illumination light emitting diodes (LED). Circuit 15-AJ7 (GN/BU) is spliced off 15-AJ1 (GN/BU) and provides voltage for the driver window control, the front passenger window control and the driver window one-touch down control. Circuit 15-AJ15 (GN/BK) is spliced off 15-AJ1 (GN/BU) and provides voltage to the one-touch down relay (switch side). The driver window control switch is grounded through circuit 31-AJ7 (BK). The one-touch down relay is grounded through circuit 31-AJ15 (BK). When the driver window control switch is moved to the window down position, voltage is supplied to the one-touch down relay coil on circuit 15S-AJ40 (GN/BK). The one-touch down relay is switched from ground contact to voltage contact providing voltage to the driver window motor on circuit 32-AJ26 (WH). The driver window motor is connected to the driver window control switch on circuit 33-AJ26 (YE) which provides ground. When the driver window control switch is moved to the window up position, voltage is supplied to the driver window motor on circuit 33-AJ26 (YE). Circuit 32-AJ26 (WH) connects the driver window motor to the one-touch down relay switch which is in the rest (grounded) position. The one-touch down relay is grounded through circuit 31-AJ15 (BK).
