Outlet Adjustment
Your vehicle may have rear seat outlets that can be
used to adjust the airflow toward either seating area, the
floor or upward. Move the control in the center of
each outlet in any direction to direct airflow.
TrailBlazer EXT
To operate the rear air conditioning system, the front air
conditioning system must be on. With the front air
conditioning system off, the rear system controls can
only be used to circulate air in the rear of the vehicle.
To adjust the airflow
speed, turn the fan knob
(driver override switch),
located on the floor
console to 1, 2 or 3. The
rear mode and
temperature position will
now mimic the front control
system mode and
passenger side
temperature.
H(Panel): When panel mode is selected in the front
controller, the rear system will distribute air from the four
headliner outlets.
