Question about 2010 Ford F-150

1 Answer

2010 F150 Lariat. Dual climate control works only on passenger side. Rear temperature controls work fine. Driver side or left vents only blow hot air. Regardless if AC is turned on or temperature control is put in auto mode. Everyvent blows proper temperature air except the two driver side vents. I've read forums to try to diagnose, vould be upper blend acuator or the climate control unit. After reading so many posts, I am not convinced it is the climate control unit. Any ideas? Also, the unit does not make any clicking sound, like a stuck actuator would make, when I put into auto mode or change setting from 60 to 90.

If the driver's blend door actuator has failed completely, or the wiring to it is damaged, you will not hear any clicking. Check for appropriate voltage at the blend door actuator, and determine from there if it's the actuator or the control unit.

I have a 2010 f150 lariat dual climate and passenger side blows cold and driver side is warm I don't hear any clicking from changing the temps like they say u hear it the blend door how do I diagnose


Some vehicles have a DCCV that controls flow of coolant to one side and the other. Don't know if yours does or not. And you won't hear an electric blend door motor very easily. don-ohio

My 2010 F150 Lariat. The heater blows warm air on driver side but blows cold air on passenger side. What could be the problem?


Does it have dual zone climate? If so, you have to adjust the passenger side. If it still doesn't work, check for vacuum hose off in engine compartment, going into the firewall.

you really need help from a dealer tech if you cant read it in your own question, i would point out that dealer test equipment is most reliable, and use of service bulletins to find whats the latest fix for this kind of issue on this make and model. you are asking to research and find what he fixes daily. please consult them to get answer if you can.. if they are not available where you are there is always benz world and pelican. some technicians frequent those sites and answer what they can.

Heat comes thru driver's side vents, but blows cold air thru passenger side vents


You likely have a faulty blend door. It could be electrically, mechanically related, or even a broken door. It may be the blend door motor, or possibly the temp sensor.

Passenger side blows hot air when front control set to Air


you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

Dual Temperature controls inside - 2002 lincoln ls


The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.

This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.
