Ford Super Duty (1999-2016) :: 2001 F250 - Defrost Stuck / Won't Come Off
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.

Last 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 .....

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.

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?

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.

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?

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?

2006 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 RepliesFord Super Duty (1999-2016) :: 2006 F250 - Climate Control / AC Vents To Defrost And Blow Normal Air Through
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.

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.

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?

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.

Like the title says; I have a 2001 F350 with No blower Motor and Just Defrost, it is actually a friends, he is building a fence, and I am looking into the truck problem. The just defrost is probably a vacuum issue, but I do not have any book for this truck, so I have no vacuum or wiring diagrams. As far as the blower motor, I am thinking switch or motor, fuse has been checked? Is there any other "control" box involved with this year/model? Also any dash tear-out instructions, to make the access easier?

Finally finishing up my 2001 F250SD 4X4 project. Decided to pull down the front axle to replace the dust seals. I've got everything apart including the large knuckle seals. Tried to pull the passenger side axle out but it only moves about an inch to an inch and a half before it stops. Took off the differential cover to look for damage or something obvious but I don't see anything wrong. The axle is moving within the splines of the spider gear but that's it. Stumped and sitting on jacks!

So I just got an 01 f250, 5.4. Really loving this truck so far. Noticed as I was driving my gas gauge is stuck at full. One time it randomly dropped down to about half tank where I think it should be, but it jumped back up to full. Anything to suggest trying? I tried nailing a speed bump to knock the float loose at 30 and I'm not sure if it worked. Gauge goes to E when I shut the truck off, but as soon as I turn it on it jumps up to full. Should I try hitting the tank with a mallet?
View 6 RepliesFord Super Duty (1999-2016) :: 2001 F250 - Stuck Brake Pistons
I am a few DAYS into a project changing my ball joints on my 2001 F250SD 4wd.
Latest issue is I can't get the brakes back on. One of the pistons was pressed out making replacing the calipers onto the rotor impossible. Fiddling with things has only made it worse.
The higher piston is stuck extended, and the other piston doesn't even budge.
The truck is our only vehicle, and I have been working on it since Tuesday night. It looked like it was going to be done today, but I can't put it all back together now.
That piston will not move. I've tried opening the bleeder and taking a clamp to it but all I get it a few more drops of fluid, no visible movement.
A while ago it looked like this. I got it to move in a little, but it is firmly stuck.
I'm wondering if I can pull it all the way out and clean/sand polish it. Can I use a quick-clamp on the rubber section of brake line to isolate the calipers so I can pull the piston out without draining all the brake fluid from higher in the system? And what do I do about the other piston that doesn't seem to be moving at all? Grab with big pliers and twist/pull?
Some of us just have a knack for finding layer upon layer of problems on projects...
Ford Super Duty (1999-2016) :: Mirror Defrost Comes On?
Got the new truck on Monday and I am trying to figure it all out
The mirror defrost comes on with the rear window defrost, my question here is does the defrost image on the mirror light up when on?
Ford Super Duty (1999-2016) :: A/C Blowing Out Defrost Only
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.

My 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.
