Normal Operation
The LH window control switch has 2 separate power sources for each front power window. The LH window control switch receives 12 volts from the accessory delay relay 2 on circuit 400 (LB/BK) for the LH window and receives 12 volts from the accessory delay relay 1 on circuit 170 (RD/LB) for the RH window. The accessory delay relay 2 receives 12 volts from the BEC fuse 6 (30A) on circuit 964 (DG/LG) for the LH window. Accessory delay relay 1 receives 12 volts from the BEC fuse 10 (30A) on circuit 296 (WH/VT) for the RH window. The LH window control switch is grounded on circuit 1205 (BK) for the driver and passenger power windows. The accessory delay relays are controlled by the SJB.
