Is this normal for a 2001 Screw ?????
I own a 2001 F150 Screw, and have noticed the following when
the I have the temp dash **** is turned CCW (to the left) all
the way to the coldest setting.
The "PANEL&FLOOR" **** kicks in the AC clutch and is pouring
out ice cold air (just like in the A/C and MAX A/C modes.
Is this normal ?????
Heres the selections or modes that kick in the AC clutch.
"MAX A/C"
"A/C"
PANEL (does not activate A/C clutch)
"PANEL & FLOOR"
"FLOOR" (does not activate A/C clutch)
"FR & DEF"
"DEF"
Most of the modes are no brainers and should activate or kick in
the A/C clutch. But, "FLOOR" does not and "PANEL" does not...so
why would "PANEL & FLOOR" kick in the A/C clutch ????
Thanks, TMeyers-Colorado

No...you don't understand !!!
Panel doesn't
Floor doesn't
But Panel/Floor does
Makes absolutely no sense to me
dehumidifying the air makes sense for defrost modes only
but not for Panel/Floor combined....while Panel doesn't
and Floor doesn't

You're not alone
My 2002 Screw does the exact same thing as you describe. I thought something was wrong at first, but after consulting the owners manual and asking the dealer...it is exactly like you say.
I personally wish there was an "A/C" button to push to control when the a/c comes on. I used to like running panel/floor mode in my Jeep without turning the a/c on...with the Ford I can't.
It's another one of those things.

I noticed the same thing when I got mine. Read your owners manual. The system is designed to run the AC on the Panel/Floor setting when the temp outside is greater than 40 or 45 degrees. It will work like the heater if your turn the temp dial to the right, but the compressor still runs. Hope this helps.

I agree, that is what I miss the most from my Bronco II, the ability to turn AC on/off with a button.

This is the definition of operation from the Ford Service Manual:
When MAX A/C is selected:
-The air inlet duct door is at full vacuum, closing off outside air and admitting only recirculated air.
-The panel/defrost door is at full vacuum and the floor/panel door is in the no vacuum position, directing airflow to the instrument panel A/C register (19893).
-The temperature is usually set for maximum cold but may be heated if desired.
-Air will be picked up at the recirculation opening by the blower motor (19805). With the A/C control set for maximum cold, airflow across the A/C evaporator core will be diverted past the heater core (18476) and then directed into the passenger compartment through the instrument panel A/C register. There is also some airflow to the AC side window demisters.
-The A/C compressor will be enabled when MAX A/C is selected.
-The blower motor is on.
When A/C is selected:
-The air inlet duct door is in the no vacuum position, blocking recirculated air and admitting outside air.
-The panel/defrost door is at full vacuum and the floor/panel door is in the no vacuum position, directing airflow to the instrument panel A/C registers.
-The temperature may be raised if desired.
-The A/C compressor will be enabled when A/C is selected.
-The blower motor is on.
When VENT is selected:
-The air inlet duct door, with no vacuum being applied, will block recirculated air and admit outside air. From there, air flows through the system to the instrument panel A/C registers.
-The floor/panel door is in the no vacuum position to block airflow to the heater outlet floor duct (18C433).
-The panel/defrost door is at full vacuum, closing off airflow to the windshield defroster hose nozzle (18490). There is also some airflow to the A/C side window demisters.
-The temperature can be adjusted to heat the air but air cannot be cooled below outside temperature.
-The A/C compressor will be disabled when VENT is selected.
-The blower motor is on.
When OFF is selected:
-The A/C inlet duct door is at full vacuum, closing off outside air and admitting only recirculated air.
-The panel/defrost door is in the no vacuum position, closing the passage to the instrument panel A/C registers.
-The floor/panel door is at full vacuum, closing the passages to the panel/defrost outlets.
-The blower motor and the A/C compressor are off.
When PANEL/FLOOR is selected:
-The air inlet duct door is at no vacuum, blocking the recirculated air passage and admitting outside air.
-The panel/defrost door is at full vacuum, closing off airflow to the windshield defroster hose nozzle.
-The floor/panel door is in the partial vacuum position, allowing airflow to both the heater outlet floor duct and the instrument panel A/C registers. There is also some airflow to the A/C side window demisters.
-The A/C compressor will be enabled when PANEL/FLOOR is selected.
-The blower motor is on.
When FLOOR is selected:
-The air inlet duct door is in the no vacuum position, blocking recirculated air and admitting outside air.
-The floor/panel door is in the full vacuum position, directing all airflow to the heater outlet floor duct.
-The temperature can be adjusted to mix airflowing through and around the heater core to achieve the desired temperature level.
-The panel/defrost door is in the no vacuum position, blocking air circulation to the instrument panel A/C registers.
-The A/C compressor will be disabled when FLOOR is selected.
-The blower motor is on.
When FLOOR/DEFROST is selected:
-The air inlet duct door is in the no vacuum position blocking recirculated air and admitting outside air.
-The panel/defrost door is in the no vacuum position directing airflow to the windshield defroster hose nozzle.
-The floor/panel door is in the partial vacuum position, allowing airflow to both the windshield defroster hose nozzle and the heater outlet floor duct. There is also some airflow to the A/C side window demisters.
-The A/C compressor will be enabled when FLOOR/DEFROST is selected to dehumidify the air and reduce windshield fogging.
-The blower motor is on.
When DEFROST is selected:
-The air inlet door is in the no vacuum position, admitting outside air.
-Both the panel/defrost door and the floor/panel door are in the no vacuum position so that most of the incoming air is directed to the windshield defroster hose nozzle. There is also airflow to the A/C side window demisters.
-The temperature setting will determine the amount of air that is directed through the heater core and the amount that bypasses the heater core.
-The A/C compressor will be enabled when DEFROST is selected to dehumidify the air and reduce windshield fogging.
-The blower motor is on.
When MAX A/C is selected:
-The air inlet duct door is at full vacuum, closing off outside air and admitting only recirculated air.
-The panel/defrost door is at full vacuum and the floor/panel door is in the no vacuum position, directing airflow to the instrument panel A/C register (19893).

Actually I like this feature, if you don't know about it you will kill your gas mileage, but you can just turn the temp more to warm and the compressor will not come on as often. But in San Diego when it gets really hot out, I can turn this on and crank the fan, then I have cold air on my feet and from the vents, plus the vents under the front chairs can blow cold air to the back a bit and keep the passengers feet cool as well.
