Normal Operation

The RH front window control switch receives delayed accessory power from the LH front window control switch through circuit CPW14 (VT/WH) when the window lock switch is set to the UNLOCK position, and the delayed accessory feature is active. When the RH front window is operated in the up direction from the RH front window control switch, power is sent to the RH front window motor through circuit CPW20 (YE/BK) and ground through circuit CPW19 (VT). When the RH front window is operated in the down direction from the RH front window control switch, power is sent to the RH front window motor through circuit CPW19 (VT) and ground through circuit CPW20 (YE/BK).

The LH rear window control switch receives delayed accessory power from the LH front window control switch through circuit CPW14 (VT/WH) 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 CPW21 (BN) and ground through circuit CPW22 (GN/VT). 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 CPW22 (GN/VT) and ground through circuit CPW21 (BN).

The RH rear window control switch receives delayed accessory power from the LH front window control switch through circuit CPW14 (VT/WH) 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 down direction from the RH rear window control switch, power is sent to the RH rear window motor through circuit CPW23 (GY) and ground through circuit CPW24 (WH/VT).

Window Operation From LH Front Switch

When the RH front power window is operated in the up direction from the LH front window control switch, power is sent to the RH front window control switch through circuit CPW13 (GY/RD), which transfers power to the RH front window motor through circuit CPW20 (YE/BK).

Ground is provided to the RH front window switch through circuit CPW13 (GY/RD), which transfers ground to the RH front window motor through circuit CPW20 (YE/BK).

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 CPW16 (BU/OG), which transfers power to the LH rear window motor through circuit CPW21 (BN). Ground is provided to the LH rear window switch through circuit CPW15 (YE), which transfers ground to the LH rear window motor through circuit CPW22 (GN/VT).

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 CPW15 (YE), which transfers power to the LH rear window motor through circuit CPW22 (GN/VT). Ground is provided 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 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 CPW18 (GY/VT), which transfers power to the RH rear window motor through circuit CPW24 (WH/VT). Ground is sent to the RH rear window switch through circuit CPW17 (BN/GN), which transfers ground to the RH rear window motor through circuit CPW23 (GY).

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 CPW17 (BN/GN), which transfers power to the RH rear window motor through circuit CPW23 (GY).
