Ford Super Duty (1999-2016) :: F250 - AC Blowing Through Defrost
1999 F250 7.3 4x4 switch on dash with manual hubs. No visual vacuum hoses cracked.
Not sure what this component is but when I wiggle the wire at the orange cap a small motor kicks on.

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?

My defrost is stuck no matter which way I turn the control it won't come off. It just started doing this today. I think it might be a vacuum leak. When I turn my switch on the pump still clicking whether or not it's pumping.

My 2005 F-250 6.0 liter Diesel FX4 Lariat is blowing AC through defrost only all the time. I have manual locking hubs and when I engage 4x4 it works perfectly through the ESOF switch. So I am assuming the vacuum pump and lines to the hubs are in good working order but there is possibly a cracked line or fuse blown? I've only had the truck for 2 days and it just happened after purchase. I'm a little unfamiliar with checking vacuum but have done reading and I believe I can do it. I am going to get a manual hand pump and pump to 20lbs and loss shouldn't exceed 1lb per minute. I just need to know which direction to look. Everyone else had their 4x4 not working and I seem to be the only one posting that has ESOF 4x4 capability when the defrost only issue is on.

My 2005 F250 just had the cab off in December for head studs and gaskets. Its a Crew Cab short bed FX4 so it has ESOF. When I engage 4x4 the blower will switch from blowing air out of the vents to blowing air out of the windshield defrost. Is a vacuum line plugged in wrong somewhere, or is one cracked? Trying to figure this out, its rather annoying

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?

My 2005 Ford F250 6.0 diesel CLIMATE CONTROL DEFAULTS TO DEFROST mode all the time now. For some reason I'll turn on the AC and it is either already in defrost or changes to it no matter what I do. Is the head unit in the dash the problem or is it a vacuum leak or an electrical issue?

2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?
View 1 RepliesFord Super Duty (1999-2016) :: 2006 F250 - Climate Control / AC Vents To Defrost And Blow Normal Air Through
I have a 2006 F-250 Super Cab with climate control. The last three years when the temp exceeds about 85 degrees outside it acts up. It will switch from the AC vents to defrost and blow normal air through, not ac cold. Then it will switch back, when doing so I can hear the internal deflector shudder. It will do this every few minutes. It is extremely annoying. All other times of the year it works fine. My local dealer had the truck last year, but could not find anything wrong. I have used the search and also Googled and while I find similar problems nothing exactly the same.

I have a older minimax with the latest updates and have noticed that under full acceleration the tranny seems to rev up faster than the truck is accelerating. This occurs i think in 3rd gear like accelerating onto a on ramp etc. Kinda like its slipping if you know what I mean. I'm running the mild tunes in tow mode. Everything else seems ok.

Ford Super Duty (1999-2016) :: 2015 F250 - Hissing Or Whistling Noise While Accelerating
I have a 2015 ford f250 xlt crew cab, 6.2, fx4 with about 1200 miles on it. My questions are, I have noticed a hissing or whistling noise while accelerating. I took to dealer and was told it was the throttle plates not closing all the way.I was told they all do this. Normal? Very annoying noise with windows down. Another noise I have been having is the brake pedal makes a popping noise while applying pressure to brakes. Dealer said brake pedal assembly was out of alignment. They said was out of alignment 1/8". After adjustment within a few days popping started again.

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

My F250 6.4, 3.73 Crew Cab Short bed vibrates when accelerating from a stop with my 5th wheel on. The 5th wheel weighs 12K. It is a medium to high frequency vibration that is felt throughout the entire truck. It continues through the shift into 2nd (TorqueShift Tranny). The harder you accelerate the more you feel it.
It does not occur if truck is unloaded and you accelerate at full throttle. Is this normal or should I get it looked at?
Ford Super Duty (1999-2016) :: 2011 F250 - Fan Is Making A Loud Sound As The Motor Is Accelerating
Picked up a new to me 2011 F250 Lariat. She had a few odds and ends to take care of, but I was ok with that. So far I fixed the reverse sensors (2 were out) creaking in the back (leaf spring bushings needed a little Lithium Grease) Squeak in the back (tailgate step needed a little greasing). Now on to my next problem!
This is my first 6.2l (first f250 in general). Truck starts up great and idles quite. Taking off driving, it sounds loud as hell under the hood. To me it sounds like the Fan is making a loud sound as the motor is accelerating. It is more noticeable when you really floor it. Prior to this I owned a 2010 F150 and I know stomping on it the motor really revs up, but this other sound to me isn't right/normal. Googling around, the closest I found to it was:
Loud "Air" Sound Upon Accelerating 2002 FORD EXPEDITION - fan clutch! - YouTube
Granted it's for an expedition, but the sound is damn near identical. Looking on youtube at 1 or 2 videos of a f250 doing a 0-60 all I heard was the sound of the motor revving, so that has me convinced the sound I'm hearing is not normal. I'm 99% convinced it has to be the fan clutch.
Ford Super Duty (1999-2016) :: 2007 F250 - Shimmy When Accelerating From A Stop / Turning Right Or Left
2007 F250 SD Crew Cab Long Bed 4X4 with 6.0. Bulletproofed, leveling springs, 5k firestone airbags, upgraded brakes, new front driveshaft and new universals and carrier bearing on rear u joint.
The issue: When accelerating from a stop or a slow rolling start, turning right or left, I get a shimmy (vibration) that seems to be coming from under my feet. Not a violent shimmy, but enough to make me certain that something is loose or out of alignment in the drivetrain. IT IS NOT THE REAR END as friends have constantly told me. Rear end was serviced and cluth packs lubricated with no change in issue.
What I've done: Changed transfer case fluid, new front driveshaft, new u joints and carrier bearing on rear driveshaft. There has been no improvement after these repairs, if anything the vibration is a little worse and easier to induce.
I've been chasing this problem for over a year. Going to be pulling a Toy Hauler out west this falls and really need to repair this for my piece of mind..
