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 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.
View 12 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 Replies2008 F-350 Lariat, 6.4L, dual climate control. The passenger side blows ONLY hot air whereas driver side seems to blow whatever is called for. Is it right to assume this is the passenger side actuator, and this actuator is the "easy" one to replace (i.e. not pulling dash)? I read in another thread that there might be a question on determining the correct one to replace, so therefore I ask for clarification. How to verify if my assumption wrong?
View 4 RepliesJust bought the truck and when remote starting it i noticed it is turning on the heat. Having read a bunch of different posts it sounds like the climate control would be set to automatic which i would like to have it just use were i set my controls. Problem is i do not have any options on the instrument cluster for climate control and no auto button the the heater controls themselves. I would think that means i do not have automatic climate control but it is doing it. How to turn it off?
View 6 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 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 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 RepliesLast Oct. I noticed that my ac/heater started to intermittently stop blowing from AC fresh air/recir/vent/etc. mode and stick to defrost only. Do I have a bad switch and or a vacuum issue here? It's a '01 F350 CC 7.3 .....
View 6 RepliesI can't seem to get my heated seats to come on when I use the remote start. Is this possible? I assume the supplemental heater comes on behind the scenes. Is there a temperature differential between the climate setting and the outside temperature? If so what is the delta? If it's 40 degrees outside and my climate is set at 60 degrees...will the supplemental heater come on? How about the rear window defroster and heated seats, can I make them come on when remote started? Same question for the seat cooling...in a few months.
My truck is a 2012 Ultimate Lariat 6.7L ......
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 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 a2011 f-250 in my fleet, manual a/c and just the other day it shut off like a switch, when you start the truck it comes on and the buttons all work but after 6 seconds it goes dead, no lights, no blower nothing, everything else works fine. I have also noticed when you first start when the radio goes from the station to the clock thats when the climate unit shuts off. talked to the dealer they said they never sell and control heads and i doubt its that cause it works on first start.
View 6 Replies2006 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 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 RepliesI have a 2009 F350 and use it almost exclusively for towing. Every time I stop to fill up or eat or whatever I have to push the tow haul button again when I start the truck- no big deal really just annoying at times because I don't always remember to turn it back on. Is there a way to have it turn on with the button and not turn off until I push it again (even after the trucks been turned off)? I suppose while we're on the subject same with the heated seats?
View 12 RepliesWhat all would be involved in swapping from regular ac controls to automatic climate control like the lariats have on a 2015 xlt superduty?

View 11 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 RepliesMy blower works half of the time...from what I have researched it is more than likely the resistor. The thing is I can't find it..all the videos and pictures looks like they are the **** control control. Where this is located for the dual climate control?
