Windows: Description and Operation
POWER WINDOWS DESCRIPTION AND OPERATION
POWER WINDOWS SYSTEM COMPONENTS
The Power Window System consists of the following components:
- Driver window switch.
- Front passenger window switch.
- Left rear (LR) window switch.
- Right rear (RR) window switch.
- Window regulator motors in each of the doors.
- RETAINED ACCSRY PWR Circuit Breaker 30-amp.
POWER WINDOWS SYSTEM CONTROLS
The Power Windows System can be controlled by a power window up or down switch activation
DRIVER WINDOW OPERATION
When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and the driver window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing the window to open. When the driver window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction and the window closes.
The driver window switch also controls the front passenger, left rear (LR), and right rear (RR) windows.
EXPRESS DOWN FEATURE
The driver window will travel to the fully down position when the driver window switch is pressed past the first detent. Pressing the driver window switch to the up position will cancel the express down feature.
LOCKOUT SWITCH FEATURE
On Impala models, the driver window switch has a lockout switch which disconnects the battery positive voltage to the front passenger, left rear (LR) and right rear (RR) window switches, disabling them.
INDIVIDUAL WINDOW OPERATION
When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and an individual window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing that window to open. When the individual window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction causing that window to close.
