Check for a vacum hose under the hood on the driver side, the hose will be going into the fire wall, could have come disconnected, check for vacum and repair as needed.

I have a 2003 Ford F-150 FX4 5.4 and the AC only blows out of the defrost and help


Dustin, Sound like vacuum loss to position switch. Defrost is the default position when vacuum is lost in vent control system. Check any and all vacuum lines and connections under hood first, especially any that run through firewall. Check the attached links,instruction and guides, Good luck

Does the Erg vacuum solenoid cause the ac switching from vents to defrost


the ERG shouldn't have anything to do with what vents the AC comes out of, rather the dash switch that exists for changing from defrost to main vents to floor vents controls what vents are used.

Defrorstores stay on ,try to change to floor, ac, heat vent ,deforstores still on 1995 thunderbird lx blower motor works great.


Some cars use vacuum from the engine to open and close the doors that direct the air to different positions. It is possible that the vacuum line to the controls is cracked or disconnected.

Climate control switch don't work to change on defrost or floor or feet


Your AC switch is off. Anyway if the AC switch is on and the climate control is not flowing the cool or heat to any of the sides then it means that the AC nozzle is leaking and the pressure is just working into straight direction instead distributing to the switched position. It's a mechanical problem and not electrical at all

Hvac controls


Most units will use vacuum generated by the engine to help move the dampers. I would bet that might be your culprit.

Ac blows through defroster on max


The Climate control system in your truck has a gate that changes postition in order to change the flow of air from your face to defrost. The door is actuated by vacuum. Yours is still working otherwise it would be on defrost all the time. So you do have partial vacuum to the actuator but not enough to keep it in position when on high. Sounds like you have a vacuum leak but not bad enough (yet) to totally disable the gate.

Why does the ac on my 2003 ford f150 blow through the defroster


Most likely it is a vacuum problem. That's what controls the air flow flaps.
