Ford Super Duty (1999-2016) :: HVAC Control - A/C Only Works On Max
I just picked up this truck and have found my first undisclosed problem. The A/C only works on MAX. If you turn to any other setting, regardless of selected temp, the air blows hot. And I mean full hot! I was thinking the control panel assembly is bad?

When my hvac controls are turned to hot, I'm getting only luke warm air. When moved over to cold it feels like the a/c is on...granted it is 21 degrees here. What I've done so far:
1. Flushed the coolant system at the local COOP TBA
2. Flushed heater core-Both heater hoses are hot to the touch as well as the heater core itself. The hoses are within 10 degrees of each other tested by an infrared temp gauge.
3. Verified the blend door actuator is moving. I can see it spin while attached to the box as well as I pulled it out and plugged it in it will move from hot to cold.
4. Smacked the #$%! out of the blend door box.
The fan still functions as it should from low to high. The truck also gets up to operating temp as usual.
Is it possible the actuator is still faulty even though it moves and not going all the way to the heat side? I considered picking up a replacement but I hate to start throwing parts at it.
Did the blend door give up? The snow is here and I need the heat for those 4am waterfowl hunting trips.
Ford Super Duty (1999-2016) :: 2011 F350 - HVAC Vents Stuck
So my vents stopped actuating to different positions in my 2011 6.7 F350. I read that it could be a vacuum pump or solenoid issue. In any event, I turned 4x4 on and went down the street and made a u-turn - 4x4 seems to be on as the truck wants to hop the outside wheel when turning. I want to check the vacuum pump anyway but for the life of me cannot find it anywhere. Moreover, google turns up nothing which is making me start to believe the new trucks have a completely different system.

I'm installing an aftermarket radio in my 2004 SD. The illumination control stopped working (when I turn on the lights, the radio doesn't get darker), and now the dash and a/c panel aren't backlit any more.
This is the first time I've driven it since the new radio. I thought I might have seen a spark when testing to see which wire was the illumination control, but I'm not sure. I've got a fuse box diagram, but so far all the fuses look good.
Ford Super Duty (1999-2016) :: F250 - HVAC Blower Motor Stopped While Driving
My HVAC blower motor stopped today while the wife was driving the F250. I thought I should swap relays (with the heated mirror relay - same Ford Part Number) to rule it out or identify it as the culprit. However, since these are close to the firewall, I have a hard time getting the grip and leverage to pull the relay out of the Battery Junction Box (BJB). How to make this a bit easier?

The mirror defrost comes on with the rear window defrost, my question here is does the defrost image on the mirror light up when on?
Ford Super Duty (1999-2016) :: A/C Blowing Out Defrost Only
I have followed the vacuum lines but don't see any holes or cracked lines. I dont have the ESOF hubs so that is ruled out. Also checked the connector on the vacuum pump to make sure it still had power. Everybody says that when I turn the key to acc I should hear the vacuum pump running. I don't or do I feel it moving. Am I on the right track? I don't want to replace if not bad. Do all vacuum pumps run on keyed power? I honestly don't remember hearing it run before but that doesn't mean anything with my memory.

I was recently on a trip pulling my 32' Travel Trailer, and out of the Hvac system started blowing scalding hot air and soot and smoke into the cab. I pulled over to check things out and could find nothing wrong. When the turbo kicks in it blows even hotter. I could find nothing wrong at the time. As I got back on the road again it started again a few miles down the road.
I made it home and started checking things out. Around the dash, airbag, glove box, on the window , headliner and carpeting, is covered in soot and smoke. the computer is now telling me that ALL the doors are ajar, power locks and key fob do not work, 3/4 of the window switches do not work and 1 window does not work now. I removed the glove box and the panel underneath it to look at the HVAC system.
What I saw about made me cry. The Plastic that houses the HVAC system had started melting and the HVAC hoses have melted. I have still not found the reason for any of this to happen. Also when I got the truck a year ago the Turbo would spool up around 1800 to 2000 RPM. Now it does not spool up until around 3000 to 3250 RPM.

I have a 2012 super duty with a 6.2 in it. I bought it last winter and noticed no air getting to the defrost vents. Now in the heat, sometimes when I turn the air on, all I get is super hot air like the heater. Sometimes playing a bit will work but not always.

I have a 2000 f250 4x4 7.3 diesel. I had problems with my a/c and controls for sometime now. my a/c was blowing threw the defrost vent. I was told my blend door was bad. I bought a new blend door installed it,still doing the same thing. I was told to check my vacuum lines. I check them, they were bad. I replace my vacuum lines and my vac pump as well. that fixed my problem blowing threw the defrost vent. I can control my air flow from floor,dash vents and defrost vent. the problem I have, I not able to control my temperature when I turn my center from red to blue. It blows hot air and the air that is coming out of the vents isn't very strong at all.

I know there is a motor or switch that I can remember the name of that is in the dash somewhere that controls the Defrost and regular cabin flow. I am not good with A/C, and was wondering, what is the name of it, and is it something I can get to behind the glove box or is it very complicated?

The A/C on my 05 F250 6.0 recently would not blow out through the vents. So, I replaced the vacuum pump and the reservoir tank. Once I replaced them the A/C still starts through the defrost vents but, after a minute or so starts to blow through the vents. I also noticed that the vacuum pump never stops running. Is this normal or is there something else I need to look for?
