Normal Operation
Voltage is supplied to the passenger front, left rear and right rear power windows from the driver window control switch through circuit 170 (RD/LB). If the driver window control switch is in the lock position, the circuit is open and the windows do not operate from their respective window control switches.

Left Rear
When operating the left rear window in the down position, ground is received from the driver window control switch through circuit 317 (GY/OG). Voltage is supplied to the left rear window motor through circuit 333 (YE/RD) and ground through circuit 334 (RD/YE).

When operating the left rear window in the up direction, ground is received from the driver window control switch through circuit 316 (YE/LB). Voltage is supplied to the left rear window motor through circuit 334 (RD/YE) and ground through circuit 333 (YE/RD).

When the left rear power window is operated in the down direction from the driver window control switch, voltage is sent to left rear window control switch through circuit 316 (YE/LB), which transfers voltage to the left rear window motor through circuit 333 (YE/RD). Ground is provided to the left rear window control switch through circuit 317 (GY/OG), which transfers ground to the left rear window motor through circuit 334 (RD/YE). When the left rear window is operated in the up direction from the driver window control switch, voltage is sent to the left rear window control switch through circuit 317 (GY/OG), which transfers voltage to the left rear window motor through circuit 334 (RD/YE). Ground is provided to the left rear window control switch through circuit 316 (YE/LB), which transfers ground to the left rear window motor through circuit 333 (YE/RD).

Right Rear
When operating the right rear window in the down direction, ground is received from the driver window control switch through circuit 319 (YE/BK). Voltage is supplied to the right rear window motor through circuit 333 (YE/RD) and ground through circuit 334 (RD/YE).

When operating the right rear window in the up direction, ground is received from the driver window control switch through circuit 320 (RD/BK). Voltage is supplied to the right rear window motor through circuit 334 (RD/YE) and ground through circuit 333 (YE/RD).

When the right rear power window is operated in the down direction from the driver window control switch, voltage is sent to right rear window control switch through circuit 320 (RD/BK), which transfers voltage to the right rear window motor through circuit 333 (YE/RD). Ground is provided to the right rear window control switch through circuit 319 (YE/BK), which transfers ground to the right rear window motor through circuit 334 (RD/YE). When the right rear window is operated in the up direction from the driver window control switch, voltage is sent to the right rear window control switch through circuit 319 (YE/BK), which transfers voltage to the right rear window motor through circuit 334 (RD/YE). Ground is provided to the right rear window control switch through circuit 320 (RD/BK), which transfers ground to the right rear window motor through circuit 333 (YE/RD).
