Ford 1996 Crown Victoria Manual page 90

You can override the fan speed at any time. If
you use the thumbwheel to override the fan
speed, the EATC will continue to control the
temperature but you control the fan speed. To
return to auto fan control, press the
AUTOMATIC button. If you are operating in
one of the override functions (FLOOR, MAX
A/C, etc.), automatic fan control will continue
unless you rotate the fan thumbwheel. To return
to automatic fan control, press the AUTOMATIC
button. The EATC will return to Automatic
operation. If you want to return to any override
function, press the button for that function. The
fan speed will continue to be automatically
controlled.
Manual override buttons
Your EATC has six buttons which allow you to
make special selections. The buttons are located
along the bottom edge of the EATC control and
allow you to determine where the air will be
discharged. Pressing any override button
changes the air discharge location only. It does
not affect the ability of the system to control
temperature or the fan speed. Return to fully
Automatic operation by pushing the
AUTOMATIC button.
MAX A/C button
The MAX A/C feature allows for faster cooling
because air is drawn from inside the car. Using
inside air causes the fan to sound louder which
is normal for this selection. The Display window
will indicate MAX A/C under the selected
temperature. The airflow will be from the
instrument panel registers.
