Rear Window Operation From LH Front Switch

When the LH rear window is operated upward from the LH front window control switch, power is sent to the LH rear window control switch through circuit CPW16 (BU/OG), which transfers power to the LH rear window motor through circuit CPW21 (BN). The LH front window control switch provides ground to the LH rear window switch through circuit CPW15 (YE), which transfers ground to the LH rear window motor through circuit CPW22 (GN/VT).

When the LH rear window is operated downward from the LH front window control switch, power is sent to the LH rear window control switch through circuit CPW15 (YE), which transfers power to the LH rear window motor through circuit CPW22 (GN/VT). The LH front window control switch provides ground to the LH rear window switch through circuit CPW16 (BU/OG), which transfers ground to the LH rear window motor through circuit CPW21 (BN).

When the RH rear window is operated upward from the LH front window control switch, power is sent to the RH rear window control switch through circuit CPW18 (GY/VT), which transfers power to the RH rear window motor through circuit CPW24 (WH/VT). The LH front window control switch provides ground to the RH rear window switch through circuit CPW17 (BN/GN), which transfers ground to the RH rear window motor through circuit CPW23 (GY).

When the RH rear window is operated downward from the LH front window control switch, power is sent to the RH rear window control switch through circuit CPW17 (BN/GN), which transfers power to the RH rear window motor through circuit CPW23 (GY). The LH front window control switch provides ground to the RH rear window switch through circuit CPW18 (GY/VT), which transfers ground to the RH rear window motor through circuit CPW24 (WH/VT).
