Ford Super Duty (1999-2016) :: 2000 F250 - No Air From Dash Vents

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.

Ford Super Duty (1999-2016) :: 2011 F350 - Air Would Only Blow Through The Dash Vents

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.....

Ford Super Duty (1999-2016) :: F250 - Dash Vents Stop Blowing Under Acceleration

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?

Ford Super Duty (1999-2016) :: 2003 Excursion - Dash Vents Not Working - Just Defrost

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?

Ford Super Duty (1999-2016) :: Very Little Air Movement Through Vents

With my A/C turned up on max A/C and fan speed set on highest setting, I get very little air movement through the air vents. I have been told that starting with 2000 year models, there is a filter on the A/C fan motor. If this is true, I am sure mine needs to be changed. Looking for procedure/schematics for removal and change.

Ford Super Duty (1999-2016) :: Hot Air From Passenger Side Vents

My F-350 is only blowing hot air out of the passenger side vents, and not the drivers side. Could it be a vacuum leak or a an electrical issue? How could you troubleshoot this to find out what the problem is?

Ford Super Duty (1999-2016) :: 2012 - No Air Getting To The Defrost Vents

I have a 2012 super duty with a 6.2 in it. I bought it last winter and noticed no air getting to the defrost vents. Now in the heat, sometimes when I turn the air on, all I get is super hot air like the heater. Sometimes playing a bit will work but not always.

Ford Super Duty (1999-2016) :: A/C Will Blow Through All Vents But Front Ones

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?

Ford Super Duty (1999-2016) :: 2006 Diesel F250 - Hot Air Only Through Vents

Last week I flipped the fan switch on and noticed that only hot air was coming from the vents, even with the control set to AC. The vent control switch seems to work fine directing the air but only hot air. The temperature control does not work. The exception is when I put it on max AC I get cold air. I can't be the only one.

Ford Super Duty (1999-2016) :: No Air Blowing Out Of Vents Or Defrost For AC Or Heat

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?

Ford Super Duty (1999-2016) :: 2005 - Chemical Smell In The Cab Not From Vents?

2005 F350 Lariat crew cab a few weeks back.

My question.... I noticed a strong ammonia/super glue like smell floating around in the cab about the 3rd time i drove the pickup. Since then, it seems to do it intermittently. My first assumption was it was coming through the vents. I have done a couple experiments, and I don't believe this is the case. My wife and I were driving yesterday and she thought she noticed the smell again. while I was driving she started checking all the vents, and nothing. But when she leaned clear down near the speaker hole in the door, she said she could really smell it.

What could be causing this? I'm assuming if it was the AC it would be coming though the vents. And at this time, I don't think it is.

Ford Super Duty (1999-2016) :: Water In Heat / AC Vents After Rain?

Don't get much rain here in SoCal except during the winter. After the last rain I noticed that there was water in the heating/ac vent system - or at least that's where I think it was.

When I made a right hand turn some water slopped out onto my foot and gave me quite a shock for a second till I figured out what had happened.

I suspect that there must be some kind of drain tube for the vent system that's become clogged, but before I start crawling around under the truck and dash I figured I would ask here first. Any useful tip on clearing the clog?

Ford Super Duty (1999-2016) :: Location Of Rear Seat Vents?

I am upgrading an F150 w/ pass-through console to an F250 w/ jump seats. Have not gone to see the truck in person and am wondering where the rear air vents are located?

Reason being I have two very large dogs that own the back seat. It's basically a large dog bed. The console vents are fantastic, keeps them cool back there. I can't figure out where the vents are in a jump-seat configuration.

Ford Super Duty (1999-2016) :: 2006 - All Climate Functions Come Out Of Defrost Vents

It'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.

Ford Super Duty (1999-2016) :: Burning Smell Coming From AC Vents For About A Minute

Ford Super Duty (1999-2016) :: 2011 F350 - HVAC Vents Stuck

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.
