Ford Super Duty (1999-2016) :: 2011 F350 - Air Would Only Blow Through The Dash Vents
Oct 7, 2014
2011 F350 6.2L Gas engine. Last fall when I first started using my heat I noticed that the air would only blow through the dash vents. It will not switch over to defrost or floor. I have an XLT I am pretty sure the controls are the basic controls. there are push buttons to change from floor/vent and defrost. I do recall the summer before I had I noticed the problem I would hear a clicking sound in behind the dash. I figured something fell down the defrost vent. I see people who have had this problem on older trucks talking about an actuator. I've looked on ford parts site and I cannot find an actuator listed for the damper door. I was hoping to see what it looks like so I could try and find it in my truck.
I do have the dash pulled apart and I can reach up and manually move a lever that is connected to a cable. and I can change the air outlet to the floor, but I cannot get it to change to defrost. While I have the dash apart I also tried pressing the buttons on the heat control to see if the lever which I am moving by hand is moving at all and it is no. I was thinking if something was stuck in the system I would probably be able to feel the cable at least try to move, but it does not. The white cable which is connected to the lever which I am moving goes into the bottom of the duct work, where it goes from there, but I am assuming some kind of actuator?
This is right in front of the 4x4 shifter
Obviously behind the glove box
With the radio removed
I'm guessing this is 1 of the motors?
I stuck my camera up there to see what was there. This is as far forward as I could go on the drive rside and in front of the 4x4 shifter. You can see the end of the cable I'm assuming that is the door.....

So my vents stopped actuating to different positions in my 2011 6.7 F350. I read that it could be a vacuum pump or solenoid issue. In any event, I turned 4x4 on and went down the street and made a u-turn - 4x4 seems to be on as the truck wants to hop the outside wheel when turning. I want to check the vacuum pump anyway but for the life of me cannot find it anywhere. Moreover, google turns up nothing which is making me start to believe the new trucks have a completely different system.

So I just purchased a 2011 F350 6.7 this week...I've had absolutely no problems until I drove it to the dealer just to get it detailed...I give the salesman my key and he comes back and says it won't start...we tried numerous time to start it...put jump boxes on both batteries and nothing...had full power to all accessories but when attempting to crank it would black out on the dash screen and give me a "stop vehicle" warning....does this deal with security?....also after hassling to get rental for a hour or so,we tried agian and it fired right up?!?...also it started double honking when locking. ..is that due to the hood being up?

6 months ago AC started to only blow through Defrost, replaced EOSF and problem went away. Today my ac started to blow through defrost, switched to floor it will shift from defrost to floor, switch back to defrost, it goes back to blowing to defrost, switch to front vents, nothing stays at defrost. Air pump kicks on for 30 seconds (KOEO) then shuts off. If I disconnect a vacuum line pump turns on. I am pretty sure at this point.. its not a vacuum leak. What else should I look at?

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.

2005 F350 Lariat ..... I cant get my AC to work in my truck.
AC will not cycle on, Originally thought the system was low because I jumped the pressure switch and it cycled fine (But did not cool inside the vehicle). Checked the pressure and it was in the 40lb range on the low side. My blower will only blow on high but I assumed it was a defective fan speed control.. Possibly an issue with the climate control?

I seem to be having a run of bad luck with my dash vents. 3 of the 4 vents in the dash have broken and I would like to replace them.
Are these vents made aftermarket? If so who? The dealer wants fifty some odd dollars each.

So two weeks ago I had a battery melt on me and I replaced it. Then last week I had the other battery almost blow up on me (it was a mess and smoking). I didnt use it all weekend. Today it started right up. I drove it like 500 feet and it just died. It is very weird. Both batteries are fully charged. Relay is good. When I put in the key it does nothing. No sound no radio no clicking. However, the gps still works (the online monitoring kind). I can fold in my out revie mirrors. And I can lock and unlock the doors. and the interior overhead lights come on. Nothing else has power at all. And I can't put it in neutral. Right now the truck is blocking my driveway so nothing can get in or our of here. I am wondering if it is some type of antitheft issue...

I have a f250 with 6.8l engine. I can get air thru the defrost and to the floor, but no air thru the dash vents on me. I have traced all vacuum lines and they seem fine.

Best truck I ever had but around 200k would occasionally blow a bunch of smoke when pulling a heavy load.
My 2000 f 350 xlt triton v8 has done the same thing a couple times (about 200k miles).
The (cough) "truck expert" at my local dealer has never seen that before but its happened in 2 different trucks for me. It never caused a problem other than scaring me.
I sold the 02 last year when i got a 2011 f 250--it was 12 years and 300k miles old and never was hospitalized except for a fuel pump due to my negligence of filter.

My heater vents have been acting up. I have read that there may be a vacuum leak that causes the blend doors to default to defrost...
Where the vacuum line fails? I have ESOF 4x4 and that is still working. I think there may be a correlation between engine vacuum and my vents: at cruising or idle the vents work ok (not perfect) and under acceleration (less vacuum) the dash vents stop blowing.
I thought that the blend doors had their own vacuum pump, so I do not know why things change at different amount of throttle?

Air is only blowing through the defrost vents. No matter what I do - try to turn vents, A/C, heat, fresh air, recirculating, etc. Assume it's a switch or fuse issue somewhere. How to fix it?

I can hear and see the blower motor running great. I just have very little air flow through the vents, defroster etc... is there a blower motor door between motor and vents. 2011 F750 xl superduty ....

2006 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.

Came out to start my truck today a hit the key and got nothing. After I settled down from being upset about my truck already giving me trouble (bought it in Nov and had 25k miles on it, 35k now) and that I should have stayed with a Chevrolet, I was able to start it by crawling under and jumping the started with a screwdriver. The truck started up no problem and got me home where I did some troubleshooting. Looks like I dont get solenoid power at the starter (just main power), the relays and fuses checked out, anhe d it looks like the key is still programmed.
I had been getting what seamed like a delayed start every now and again that was going on for a while, but thought it was just me. The next items I thought that may be the culprit are the neutral safety switch or the ignition switch. The gear selector seams to work fine and it wont start in either P or N, the backup camera turns on and nothing seams to be incorrectly working on that account. Also, the truck is a 2011 F350 Crew Cab 4wd Lariat with the 6.2 gas motor.

My 4wd doesn't engage on my 04 powerstroke. The dash light doesn't come on. I replaced the relays, switch, and 4wd module, I checked the fuses, all fuses are good, but fuse 31 doesn't get power to it. The voltage at the relay block reads 12v with the fuses out, but drops to around 7v when they're plugged in. I have no power to the Tcase (.15v).

I bought my 2005 F-350 Diesel 6.0 Brand New. Whenever my low fuel light comes on, I only have a few miles to go before I run out of diesel. Is there a way to adjust this light so it will come on with maybe 20-30 miles to go before running out? Its seems to only have maybe a gallon in the tank when this light comes on...

I need to remove the panel to the left of the dash that has the headlight switch and AC outlet in it.

I have an '02 F350 PS. Recently I have been hearing a crackling noise coming from under the dash on the drivers side sometimes at idle but more often when driving. Th strange thing about it is that the noise stops as soon as there is any pressure on the brake pedal. The noise sounds electrical in nature but I can't be sure. I want to crawl under the dash to try and ID the source but it is not consistent and I have not been able to do so when I hear it. What it might be?

I did this years ago in my 04 Mini Cooper, although there were no vacuum lines, just about a 30 wire wiring harness. simple enough, extended each wire 1 by 1 so it reached where i needed it to be for the new location.
How hard would this be to move it? i haven't even taken the control panel out of the dash yet, i will do that tomorrow and see what's back there, it's been a while since i removed one so i don't recall what the wires were like, if there were vacuum lines, etc.
Until tomorrow when i can look for myself, if there is enough slack in the entire harness/vacuum lines/etc to move it slightly up/down/left/right, but in the same general area? I don't really want to move it, but here's the reasoning. my Joying android double din head unit doesn't fit. it fits in the opening in the dash behind the bezel:
And I've trimmed the little "lips/tabs" on the bezel radio opening completely off, there's nothing else to trim, and the plastic trim around the face of the radio prevents it from sliding in flush with the bezel, so the face of the screen is parallel with the face of the a/c controls, like the stock radio is.
kind of hard to tell but if you look close where the sanding marks are, it's completely flat with the main part of the bezel. normal double din installs in 99-04's i believe you only have to trim either the top/bottom, or the side tabs depending on the unit/stereo installation kit/trim pieces, but usually double dins will fit after trimming these tabs. this android unit is slightly larger due to the plastic trim around the screen (not removable, it's part of the actual screen) so that's why i'm having a hard time.
The only thing i can think of is to completely remove that plastic "bar" that's right in between the radio and the a/c controls, the one that's sort of rounded on the front. if i remove that, the radio will fit, but then it will cut into the a/c controls. now i'm not sure if i can maybe trim more bezel off directly under the a/c (there's not much of the bezel left directly under it to even trim) and move the a/c down just enough to allow the radio to fit right above it....or do something more in depth, and relocate it completely, either somewhere else on the dash, maybe in my future full length custom console i plan to build to house a subwoofer or two, as well as cup holders etc....or, which i think would be my favorite but the most work, and probably not even worth it because i THINK there's vacuum lines on the controls, is to move it to the overhead console like the same exact control is mounted in my excursion (which controls the rear air). i think i even have a spare excursion console that i could use so it houses the controls like stock and looks 100% factory rather than fiber glassing etc...i'd really like that option, it'd give me more space in the bezel to mount my clarion 1/2 DIN equalizer near the radio (which i probably can't if i leave the a/c in the dash) and it would keep me from possibly putting the a/c in the console, that's a last resort for me i think.
This is sorta neat how they moved it, i'd assume there may be enough play in the harness to move it here without having the cut/extend anything? that's what this thread is for essentially, so i can find that out .. I also don't know if i want to even put the a/c there because I'm not 100% sure yet, but i may bring my console (at an angle/curve) all the way up to that point on the dash where my console build will meet the dash. Not sure if I'm going to stop it below that point and retain the stock pull out cup holders and little cubby, or just remove that completely and bring the console to the bottom of the actual bezel. Looking for any pics of the back of the a/c controls (again, 2004 f350, non digital controls, same as in that last picture above). As well as info on how to go about extending things if it's doable without being over the top work to complete it.

This is my "03 F350 single wheel 7.3 automatic 4x4. For quite some time now I have to manually lock the front hubs. Maybe it would work automatically, maybe not, and now I always have to manually lock the hubs.....but I can live with that. The problem now is that the selector switch on the dash isn't working or something else is preventing the transfer case from going into 4x4. The 4x4 light on the dash also does not come on.
I have checked all the fuses and they are good, I do not have a owners manual so I don't know what to look for in the fusebox. Perhaps it is on a relay? Also, I would like to check the dash switch for power coming and going but how do I get the switch out of the dash? I'm afraid I'll break the bezel around the switch if I pry too much.
