Auxiliary Heater And Air Conditioner (If Equipped) - Ford Econoline/Club Wagon E-150 Owner's Manual

Auxiliary Heater and Air
Conditioner (If equipped)
If your vehicle is equipped with a factory
installed auxiliary unit (heater or heater/air
conditioner), the front control assembly will
include separate switches for FRONT and REAR
fan control. Fan speed for front and rear systems
can be set as desired by adjusting these switches.
In addition, on vehicles equipped with auxiliary
A/C, an auxiliary unit fan switch is located in
the headliner at a location between the front and
rear seats.
To control the auxiliary fan with this switch,
the rear fan switch on the front control must
be in the REAR CONTROL position.
NOTE: The air flow from the auxiliary unit is
discharged from the headliner
registers (if so equipped) or the A/C
register (untrimmed vehicles) when
front control selector is in MAX A/C,
NORM A/C and VENT only, and from
floor registers when front control is in
FLOOR FLR/DEF and DEF only.
The auxiliary unit does not provide for
mixing of hot and cold air; adjustment of
temperature in the rear may be accomplished
by increasing or decreasing the rear fan
speed.
