Power Window System Controls

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.

The LF power window master switch can control the up and down functions of all the windows in the vehicle. The passenger door power window switches can only control the up and down functions of the individual window. The power window master switch also contains a lockout switch (4 door vehicles). The lockout switch controls the power window master switch lockout signal circuit. When the lockout switch is in the OFF position, the power window master switch lockout signal circuit is complete and the passenger door power window switches function normally. When the lockout switch is in the ON position, the power window master switch lockout signal circuit is interrupted and the passenger door window switches cannot control the up and down functions of the power windows.
