Liftgate (Power) - GMC Yukon 2011 Owner's Manual

The liftgate or liftglass cannot be
opened if the rear wipers are in
motion. Attempting to open the
liftgate or liftglass while the rear
wipers are in motion will cause the
release of the liftglass or liftgate to
delay until the wipers are moved off
the liftglass.
Both the liftglass and liftgate have
an electric latch. If the battery is
disconnected or has low voltage,
the liftglass and liftgate will not
open. The liftglass and liftgate will
resume operation when the battery
is reconnected and charged.
