Window switches
The push-pull type window switch
provides the GM V with a coded ground
signal. Holding a switch at the first
detent provides a single ground signal
on one wire requesting the GM V to
open the window. When released, the
ground signal is removed and the
window motor stops.
Momentarily pushing the switch to the
second detent and releasing provides an
additional ground signal on the second
wire requesting "one touch mode". The
GM V lowers the window automatically
until it reaches the end position.
The switch functions in the same
manner for window closing but the
ground signal sequence is reversed.
Note:
In Coupe models, the rear windows
switches are used for operating the
rear swing-out vent windows.
