Ford Super Duty (1999-2016) :: 2005 F250 Blowing AC Through Defrost Only All The Time
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.

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.
Ford Super Duty (1999-2016) :: 2005 - Vacuum Pump Out - A/C Being Reverted To Blowing Out The Defrost?
Haven't been on here for a while. My f250 AC vacuum pump is out. This means the AC being reverted to blowing out the defrost. I have found the defrost/vent vacuum solenoid and zip-tied it open for a vents-only experience. I just realized, without the vacuum pump, there is really no way of determining if it is on recirculate or fresh air. I wish for the recirculate so I don't get someone else's or my own exhaust in the cab. Does the system stay on recirculate without vacuum power? if not what actuator must I zip-tie next?

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 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?

I have 2005 F250 6.0 XLT. I was driving the other night and all of a sudden my dash lights went out. I noticed I was being flashed from other drivers and discovered that my parking lights are not working. A preliminary check of fuses I discovered fuse #17 (15a mini) was blown. I installed and new one and upon turning my lights on, the fuse popped again. My headlights and turn signals work properly. It appears I have a wire shorted to ground somewhere on this circuit.
The truck is completely stock with the exception of an aftermarket radio which I installed two years ago.
I checked all the fuses with my test light and they are all correct (both sides of each fuse). I disconnected the gray connector and black connector in the driver side rear of the truck to isolate the issue. New fuse pops as soon as I turn lights on. I completely removed the tail lights, trailer 7 pin connector , completely removed both headlights. I did not disconnect the roof running lights or the mirror lights. I am completely stumped.
Ford Super Duty (1999-2016) :: 2005 F250 - Horn Blowing Intermittently / Constantly
The other day I was checking out my parking aids (they kept saying something was behind me when there was nothing there) and the horn just started blowing by itself, constant on until I disconnected the batteries. Been a few days and just got back to working on it, checked the horn switch in the airbag and it is functioning fine. Hooked the batteries back up, no horn, but after a couple of minutes I start getting little honks out of it, then locked on again. Where I should go from here? Truck was parked, switch off, engine off today when I hooked the batteries up. Never started it or turned the key on.

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 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?
View 8 RepliesFord Super Duty (1999-2016) :: AC Quits Blowing Out Of Forward Vents And Goes Into Defrost When Activate 4WD
02 F250 with 7.3. When I activate the 4WD, my light comes on, the A/C quits blowing out of the forward vents and goes into defrost and no 4WD. If I sit and wait a bit, the air again blows out the front vents and the 4WD engages. I figure I have a vacuum leak somewhere in the 4WD system. Is there a common place for this to happen or do I need to trace the whole system down? Also my manual hubs has never been turned and of course they won't. I know better than use a wrench so is there a easy way to free them up or just go ahead and disassemble and clean?

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?

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.
View 2 RepliesFord Super Duty (1999-2016) :: 2005 F350 - Vent Stuck On Defrost
I 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?

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.
