Normal Operation
12 volts are supplied from the BEC fuse 6 (30A) to the accessory delay relay 2 on circuit 964 (DB/LG). The accessory delay relay 2 then supplies 12 volts to the LH window control switch on circuit 400 (LB/BK). When the driver window control switch is pressed in the UP position, the LH window control switch directs 12 volts to the driver window motor on circuit 333 (YE/RD) and ground on circuit 334 (RD/YE). When the driver window control switch is pressed in the DOWN position, the LH window control switch directs 12 voltsto the driver window motor on circuit 334 (RD/YE) and ground on circuit 333 (YE/RD). The LH window control switch is grounded through circuit 1205 (BK). The accessory delay relays are controlled by the SJB.
