Ford Super Duty (1999-2016) :: V10 Switching To Defrost At Times While Towing Usually Above 65 MPH
So, my 06CC V10 likes to switch to the defrost at times while I'm towing, usually above 65mph, would that be a vacuum issue? Also, the truck seems to always have hot air blowing in to the cab somewhere from the fire wall? Lastly it seems to me that the steering wheel has a lot of play in it (left/right) before the wheels actually turn, should I tighten up the steering box, or is this normal.

My truck at idle sounds like it has aftermarket cams and the exhaust coming out of the tail pipe smells really rich. when driving down the road my heater controls default to defrost. Also when I fill up with gas it takes forever to get it to fill all the way. I am lost on where to begin with the problem [ I did check the tank vent hose and their is no blockage] Possible vacuum issue?

So when I tell the truck to "play bluetooth audio" it tells me to use the screen, and then disconnects the phone from the truck completely. This a newer development, and it happens more often than not, and I can't figure out why sometimes it does this, and sometimes it doesn't. Every other interface between the phone and the truck works like it should.

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 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 have a 2008 F350 and there is nothing blowing out of the vents or defrost for AC or heat. It doesn't matter what fan speed is set. Would this indicate a blower motor? Where exactly is it located and how to change?

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?
View 7 RepliesFord Super Duty (1999-2016) :: HVAC Goes To Full Defrost And 4WD Does Not Engage
I have a 2005 F350 6.0 with 4 wheel drive.
Late last winter, the 4WD stopped working. I diagnosed it to be a vacuum problem. Like a moron, I purchased a vacuum pump and threw it in there, I just figured that it was bad. It turns out the new pump I bought was bad, but the old pump was fine... Go figure. At any rate, when I switch to 4WD, my HVAC goes to full defrost and the 4WD does not engage.
I think I've narrowed the problem down to the 4WD actuator, since if I hook the vacuum pump output directly to the hubs, the 4WD works fine. If I switch it into 4WD, I can hear the vacuum releasing in the actuator, but it doesn't seem like any vacuum actually gets routed to the hubs. It just opens to atmosphere.
I've noticed that after switching to 4WD, the actuator only "Releases" the vacuum for a few seconds, and then seems to close itself. Is this normal? If I cycle the 4WD selector from 2WD to 4WD repeatedly, it will continue to cycle.
1. Is there any way to service this valve, or should I replace it?
2. Is the valve acting normally?
3. Am I on track with this repair?
