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

2003 ford expedition i just got it a week ago and the front heat works great but the back vents only blow cold air. How do i fix this?

With the car parked and engine idling, turn the ventilation control between windshield defroster and "open air ducts" to front and rear vents. Listen to pinpoint where the valves are that open and closes the air ducts. It sounds like the air duct to rear vents are blocked, and the cold air in rear air duct is coming from "outside ventilation." The air vent to allow hot air to the rear vent is stuck in "open ventilation" mode, like when you're driving in spring or summer months.

2003 F-150 air conditioner won't select panel vents. Air is cold but stays on defrost vents, for a long time. Eventually switches at stoplight. Any ideas?

Sounds like you may have some sort of vacuum leak to the control head or a faulty control head. Actuators are vacuum operated.

Climate control is on defrost only the auto

Check your vacuum pump located on the right side fenderwell. see if its running. Check the vacuum hose at the hubs for leaks or damage. repair if damaged. check for other vacuum leaks such as the grey hose going to the heater control valve.

Ford F150 2003 When I press the max cool on the AC the air comes out of the windshield defrost vent iinstead of the cabin vents and is not as cold as it use to be. Summer in Texas Help !

You did not mention if the system you have is electronic(digital control) or manual(control knobs) but what your problem is, is a vacuum leak. Defrost and heat or the default postions for no vacuum. If it works ok until you press max air Then you will need to check the outside blend door vacuum motor. It will be the white vacuum line going from the control head.

Sounds like you have a supply vacuum problem. When you lose supply vacuum to the control head it defaults to defrost.

No heat - ac stays on blowing through defrost vents

If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.

You have a vacuum leak.Defrost is the default postion(no vacuum).
See if you can locate the small black vacuum line that goes inside the vehicle on the passenger side near the heater core. The trace it back,should see it going to a canister then to the intake manifold.Make sure it is not disconnected or broken somewhere.

My 2003 windstar had the same problem. It was the vacuum cannister. That part# is F2UZ19A566A and the Ford dealer charged me $32.11 for it. Works fine now. My heat was also not working and the problem was the actuator motor.The part# for that is XF2Z19E616FB and the cost was $55.31 plus tax. Now the heat works.
