Ford F150 Heater Vent Problem

My 2004 F150 blows air only from the panel vents regardless of where I set the selector. There is a control assembly under the drivers dash on the side of the heater. It has 2 electrical connectors and an arm that seems to be connected to an internal flap or door. That arm does not move regardless of where I set the selector. Could this be the problem?
Any other ideas? Thanks.

    The blower on my F-150 (2001) no longer blows air out the front panel or floor vents...air comes out at the window vents. This is the same for heater and a/c.

Check your vacuum connections to the lever switch first. There should be no leaks.

2004 Ford econoline E-250 air condition it's not blowing through the front vent only through heater vent and leg vent


Check for cracked or loose vacuum hoses under the hood. Engine vacuum is often used to operate the vanes that direct the air according to your settings.

If these happen to be electrically operated, you may have a blown fuse or a failed actuator.

What causes the ac to blow cold in the rear but warm air in the front?


These vehicles came with 2 types of ac controls.
The vacuum control system uses vacuum to actuate the vents and ducting from hot to cold. A lot of times the HVAC vacuum line in the engine bay (black hard plastic) is either broken or disconnected from its vacuum source.
The electronic vent control: does everything at the control knob via vent actuators and the control panel itself. With this one it could be any of the components. You would have to locate them and verify operation by moving temp/vent selector.

Ford Escape Heater Vent Control


suspect a control panel issue as this HVAC (heater, ventilation, Air conditioning ) system should be all electric... If you can pull the control panel out looking at the back of it will answer your question... are the cables or just wires..

MY DISTRABUTION DIAL FOR DEF.,VENT, ETC IS IN DEFROST AND WON'T CHANGE. THE DIAL TURNS BUT NOTHING CHANGES. I NEEN SOME ADVICE ON WHAT TO DO TO FIND PROBLEM AND FIX. THANKS GENO


Here is the info. I hope the pictures show up. please rate assistance. thx.

Air distribution within the vehicle is determined by the function selector switch position. Two airflow mode doors are used to direct airflow within the heater core and evaporator core housing. The function selector switch/cable assembly is used to position these airflow mode doors. Refer to Section 412-00 for description and operation of each of the system functions.
------------------------------------------------------------------------------------------------------------------------------------
Function Selector Cable Assembly
The function selector cable assembly moves the airflow mode doors to the desired position using a 2-sided pull-pull type cable assembly. The function selector controls the cable movement. The end of the cable assembly attaches to the airflow mode door/temperature blend door actuating assembly which transfers the cable movement to the 2 airflow mode doors.
An electrical switch is incorporated into the function selector to notify the A/C switch assembly if DEFROST or FLOOR/DEFROST is selected. When DEFROST or FLOOR/DEFROST is selected, the A/C switch assembly will disable the RECIRC request button and send an A/C request to the powertrain control module (PCM) regardless of the A/C request button indicator ON/OFF status.

The vent function no longer works, i.e. won't blow


manual or electronic heater/A/C controls?

Could be loose vacuum harness on back of control head. Need to put 10" tie straps on to hold it tight to control head.

Air conditioning blows through defrost vents only


AC blows where you have your control switch set,if it only comes out your defroster have the vacuum check at the blend air doors or if you have a faulty heater control unit.

Fully warmed up; blowing hot and cold; Suzuki XL-7


Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.
