In 4-door models, the rear window child
lockout switch (
arrow
) is incorporated in
the driver's window switch block to the
left of the shifter. When activated, it
provides a constant ground signal to the
GM V, preventing the windows from
being operated from the rear door
switches.
The lockout switch ground signal is
overridden by the GM V if a passive
safety system (MRS) crash signal is
received.
Note:
In Convertible models the four-window
control switch is in the position occupied
by the rear window lockout switch in
4-door models.
Power window motors
The window motors are mounted on
cable regulators. The window motor
control circuit consists of two wires for
operating the motor in both directions.
The motors are activated by relays in the
GM V. The relays provide either power or
ground depending on the direction of
window travel. The GM V controls the
polarity based on a request to run the
window from a window switch or a
convenience opening/closing signal.
Convenience opening/closing
The GM V provides the convenience
open/close feature, providing control of
the power windows (and sunroof) from
outside the vehicle with the key in the
driver's door lock. The FZV (remote key)
provides the same function for window
opening only.
Anti-trap protection is active during
convenience closing from the driver's
Door Windows
