2004 CHEVROLET EXPRESS CARGO VAN wheelbase

If your vehicle has a 135 inch wheelbase, a rear control
panel for this system is located in the second row
behind the driver in the rear of your vehicle. A rear-seat
passenger can use this control panel to personally
adjust the temperature, the direction of the airow and
the fan speed for the rear-seating area.
The fan knob located on the front climate control panel
must be turned to REAR CNTL to allow a rear-seat
passenger to use the control panel in the rear-seating
area. Performing this action disables the front control
panel. To return control to this panel, move the fan knob
out of REAR CNTL.
Turn the center knob clockwise or counterclockwise
to change the direction of the airow in the
rear-seating area.To change the current mode, select one of the following:
D(Vent):Use this mode to direct air to the upper
outlets, with a little air directed to the oor outlets.
2(Floor):Use this mode to direct most of the air to
the oor outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to HIGH, MED (Medium) or LOW to
increase or decrease the fan speed in the rear-seating
area. Turn the knob to OFF to turn off the fan.
(Temperature Control):To increase or decrease the
temperature for the rear of the vehicle, turn the right
knob located on the climate-control panel.
The air-conditioning system on the main climate-control
panel must be turned on to direct cooled air to the
rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin
temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate-control
system, seeClimate Control System on page 3-19listed
previously in this section. For information on ventilation,
see “Outlet Adjustment” earlier in this section. Rear Climate-Control Panel
