The power window
switches are located
on each door.
Window Indexing
This feature automatically lowers the window a
small amount when the door is opened. Then, when
the door is closed, the window will raise to its full up
position. If either window does not index properly,
it could be due to loss of power. Before returning to
your dealer for service, perform the power window
initialize procedure following.
Power Window Initialize
After a power reconnect such as battery
replacement, the window index-up feature will
not function until the system is initialized. Once
power is restored, do the following:
1. Close the door.
2. Raise the window by pulling up the switch.
3. Hold the up switch for three seconds after the
window is closed. Release the switch.
4. Hold the up switch again for three seconds
and release.
