Normal Operation
The LH rear window control switch receives delayed accessory power from the LH front window control switch through circuit 170 (RD/LB) when the window lock switch is set to the UNLOCK position, and the delayed accessory feature is active. When the LH rear window is operated in the UP direction from the LH rear window control switch, power is sent to the LH rear window motor through circuit 884 (YE/BK) and ground through circuit 885 (YE/LB). When the LH rear window is operated in the DOWN direction from the LH rear window control switch, power is sent to the LH rear window motor through circuit 885 (RD/LB) and ground through circuit 884 (YE/BK).

The RH rear window control switch receives delayed accessory power from the LH front window control switch through circuit 170 (RD/LB) when the window lock switch is set to the UNLOCK position, and the delayed accessory feature is active. When the RH rear window is operated in the UP direction from the RH rear window control switch, power is sent to the RH rear window motor through circuit 882 (BN/YE) and ground through circuit 881 (BN). When the RH rear window is operated in the DOWN direction from the RH rear window control switch, power is sent to the RH rear window motor through circuit 881 (BN) and ground through circuit 882 (BN/YE).

Rear Window Operation From LH Front Switch
When the LH rear power window is operated in the UP direction from the LH front window control switch, power is sent to the LH rear window control switch through circuit 2015 (GY/BK), which transfers power to the LH rear window motor through circuit 884 (YE/BK). Ground is provided to the LH rear window switch through circuit 2014 (YE/LB), which transfers ground to the LH rear window motor through circuit 885 (YE/LB).

During LH rear power window DOWN operation from the LH front window control switch, power is sent to the LH rear window control switch through circuit 2014 (YE/LB), which transfers power to the LH rear window motor through circuit 885 (YE/LB). Ground is provided to the LH rear window switch through circuit 2015 (GY/BK), which transfers ground to the LH rear window motor through circuit 884 (YE/BK).

When the RH rear power window is operated in the UP direction from the LH front window control switch, power is sent to the RH rear window control switch through circuit 2013 (YE/BK), which transfers power to the RH rear window motor through circuit 882 (BN/YE). Ground is sent to the RH rear window switch through circuit 2012 (RD/BK), which transfers ground to the RH rear window motor through circuit 881 (BN).

During RH rear power window DOWN operation from the LH front window control switch, power is sent to the RH rear window control switch through circuit 2012 (RD/BK), which transfers power to the RH rear window motor through circuit 881 (BN). Ground is sent to the RH rear window switch through circuit 2013 (YE/BK), which transfers ground to the RH rear window motor through circuit 882 (BN/YE).
