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 will not operate from their respective window control switches.

Passenger Front
When operating the passenger front window in the DOWN position, ground is received from the driver window control switch through circuit 319 (YE/BK). Voltage is supplied to the passenger front window motor through circuit 334 (RD/YE) and ground through circuit 1159 (WH/BK).

When operating the passenger front window in the UP direction, ground is received from the driver window control switch through circuit 320 (RD/BK). Voltage is supplied to the passenger front window motor through circuit 1159 (WH/BK) and ground through circuit 334 (RD/YE).

Left rear
When operating the left rear window in the DOWN position, 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 1159 (WH/BK).

When operating the left rear window in the UP direction, 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 1159 (WH/BK) and ground through circuit 334 (RD/YE).

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 334 (RD/YE) and ground through circuit 1159 (WH/BK).

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 1159 (WH/BK) and ground through circuit 334 (RD/YE).

Window operation from the driver window control switch
When the passenger front power window is operated in the DOWN direction, power is sent to the passenger front window control switch through circuit 1505 (YE/RD), which transfers power to the passenger front window motor through circuit 334 (RD/YE). Ground is provided to the RH front window switch through circuit 313 (WH/YE), which transfers ground to the passenger front window motor through circuit 1159 (WH/LB). When the passenger front window is operated in the UP direction, power is sent to the passenger front window control switch through circuit 313 (WH/YE), which transfers power to the passenger front window motor through circuit 1159 (WH/LB). Ground is provided to the passenger front window switch through circuit 1505 (YE/RD), which transfers ground to the passenger front window motor through circuit 334 (RD/YE).

When the left rear power window is operated in the DOWN direction, voltage is sent to left rear window control switch through circuit 317 (GY/OG), which transfers power 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 1159 (WH/LB). When the left rear window is operated in the UP direction, voltage is sent to the left rear window control switch through circuit 316 (YE/LB), which transfers power to the left rear window motor through circuit 1159 (WH/LB). Ground is provided to the left rear window switch through circuit 317 (GY/OG), which transfers ground to the left rear window motor through circuit 334 (RD/YE).

When the right rear power window is operated in the DOWN direction, voltage is sent to right rear window control switch through circuit 320 (RD/BK), which transfers power to the right rear window motor through circuit 334 (RD/YE). 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 1159 (WH/LB). When the right rear window is operated in the UP direction, voltage is sent to the right rear window control switch through circuit 319 (YE/BK), which transfers power to the right rear window motor through circuit 1159 (WH/LB). Ground is provided to the right rear window switch through circuit 320 (RD/BK), which transfers ground to the right rear window motor through circuit 334 (RD/YE).
