Power Window Switch: Description and Operation
Window Switches
Individual window switches are installed in each of the three passenger doors. Window switches for all of the windows, and a child lock switch to isolate
the rear windows, are installed in the driver's door.
All of the window switches have two switching positions in each direction. The first switching position operates the window in the inching mode, where
the window moves until the switch is released or until it reaches the fully open or closed position. The second switching position operates the window in
the one-shot mode.

Anti-trap Sensors
An anti-trap sensor is installed along the top of each window aperture, just outside the travel path of the window glass. Each anti-trap sensor consists of a
rubber covered contact strip connected to ground and to a power supply from the door (front windows) or GEM (rear windows). When the anti-trap
sensor is pressed the resistance across the contact strip is reduced. If a window is being closed and the door/GEM detects a drop in resistance across the
associated anti-trap sensor, it immediately (in less than 20 milliseconds) reverses the window.
