Normal Operation
The LH rear window control switch receives power from the accessory delay relay through circuit 170 (RD/LB). The LH rear window control switch provides power to the LH rear window motor through circuit 884 (YE/BK) and ground through circuit 885 (YE/LB) to operate the LH rear window DOWN; and power through circuit 885 (YE/LB) and ground through circuit 884 (YE/BK) to operate the LH rear window UP.
When operating the LH rear window using the LH front window control switch, power is sent to the LH rear window control switch through circuit 320 (RD/BK)/316 (YE/LB) and ground through circuit 319 (YE/BK)/317 (GY/OG) to operate the LH rear window DOWN; and power through circuit 319 (YE/BK)/317 (GY/OG) and ground through circuit 320 (RD/BK)/316 (YE/LB) to operate the LH rear window UP.
