2006 F250 5.4 - While driving ac changes from vent to defrost on it own..let off gas and it will change back to vent. I replaced vacuum can under hood.. no luck.....
View 1 RepliesI 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 RepliesMy husband and I have 3 Excursions, V10, 6.0, 7.3 and I have a 6.0 250 crewcab. 3 of the 4 now blow air or heat from just the defroster unless your going at a slow speed.
View 2 RepliesI 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.
View 1 RepliesI have a 2012 F-350 SRW with a 6.7 diesel. The other day I went to push the defrost switch and noticed it does not work. All the lights work in the switches, and the temp control works, but no matter what I push, defrost or floor, it stay in the vent only. Anything I can check??
View 1 RepliesI have a problem with my vent selector on my truck. It's a 2005 f350 lariat. The vent is stuck on defrost, some times after a few mins I can get it to switch to floor but not always. I have replaced the pump, checked tank for cracks, disabled and plugged the auto hubs. The pump will shut off so I assume it's not a leak. I believe it's in the switching unit, can these be repaired? I found a lot of dust and dirt in the vac tank that had been sucked through a bad hub. I think it may need to be disassembled and cleaned. I have seen videos showing how to replace the orings in the older units. Are the newer style remote ones the same?
View 5 Replies2006 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 RepliesI 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.

Not sure what this component is but when I wiggle the wire at the orange cap a small motor kicks on.
I have a 1999 F 250. When I accelerate my AC from the vents changes to the defrost. Other than that it works great and is ice cold. Why it's doing this.
View 5 RepliesI have a 1999 F250 V10 SuperDuty. Just recently I had noticed some gray foam material laying on my passenger floor. Then about a week later my air vent near the passenger window is whistling really bad when I have the air on. I normally have that vent closed. Is there an easy fix for this? My guess is that the foam inside has deteriorated and broke apart.
View 2 RepliesThe 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?
View 5 RepliesMy 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.
View 2 RepliesMy 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.
View 11 RepliesMy 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
View 2 RepliesMy 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?
View 10 RepliesNew to me 2003 F250 Super Cab 6.8 V10. Great condition inside and out. 68,000 miles. Began smelling fuel (gas) a few days after driving it 250 miles from purchase location. Traced leak down to the top of the gas tank. Staining was visible around the rear vent. Applied about 5 psi to the tank and sprayed soap around until I saw bubbles coming from a hairline crack at the rear vent connection. Its where the fitting for the hose comes out of the tank.
My first choice would be to hot weld the crack. I'm not very comfortable with the idea of a heat source near a gas tank. I'm not sure, but the heat from the plastic welder might be hot enough to ignite fumes? Second option is to try some industrial 2 part epoxy (PIG) and seal it with that. Is there pressure inside the tank, and if so how much? Can try this fix with epoxy or JB Weld?
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?
View 2 RepliesIt's a 2006 F250 Super Duty, 4WD AT, no auto hubs, 5.4L. All climate functions come out through the defrost vents. That mean when I'm using A/C it works, but comes out the defrost vents, or if it's a cold day and I want to use the heater it comes out the defrost vents. (So does defrost! LOL) Once or twice things went back to normal, but then, once when I had some cargo on the passenger's floor, I heard a hissing sound and it all went back to the defrost vents. Been there for a while now. Dealer wants to charge an arm and leg to look at it and then all arms and legs to fix it, and wouldn't you know it's not covered on my service plan!? Remember, these 4WD front hubs are not auto. I get the idea that to do anything under the dash means I have to disassemble the entire truck down to every last bolt.
View 10 Replies2006 f350 DRW King Ranch diesel with 94,000 miles on it. When I shift in to 4x4 the AC switches to defrost and then takes 2 min to return to the vents. I imagine this is a vacuum leak issue. Where to start hunting? I pulled the dash for another install and all lines were connected. I will say the vacuum pump stays on longer than normal when the ignition is first activated.
