Ford Super Duty (1999-2016) :: Heat Only Blows Through The Defroster
2002, F250, 5.4, ZF6, 140k.
My heat only blows through the defroster. I was looking for my vacuum pump, but can't seem to find it. I find plenty of diesel threads where they show it, but mine isn't in the same location. I can actuate the diverter by hand and it will make the heat stop at the defroster and come out at your feet.
I have attached images of my rig.
Were to look for the vacuum pump? Any key spots to look for failed vacuum lines? What is this?
This is where most threads say the vacuum pump should be.
This switches from defrost to floor when operated manually.

My 1999 F 250 5.4 liter. I know I have a vacuum leak because whenever I accelerate the air conditioning coming from the vents switches to the defroster. So my question is how do I go about finding the leak? My hubs in the front are manual so I know I don't have lines going up there. I do have some mechanical capabilities I've changed water pumps alternators brakes etc. But never anything with vacuum lines or a/c.

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 an 06 F-250 Lariat with the crew cab. Even though the windows are tinted, the A/C struggles to keep the cab at 70 degrees on any given sunny day oer 80 degrees outside.
As long as you're driving on the interstate, it blows cold, but when slowing down (like a traffic jam or a stop sign) the air gets warmer and has a funny smell (like it's wet).
When I got the truck it had just gotten a new A/C compressor (160k miles). It stopped working last summer (180k miles) so I had the truck at the Ford dealer here and they replaced the A/C compressor, condenser, pressure regulator and dryer...basically all A/C components under the hood.
They tell me its working fine, but I find that hard to believe. No Ford I've ever had has had trouble keeping the cab ice cold even on the hottest days... How are your air conditioners working? Do they keep the cab cold? What I should look at?
Ford Super Duty (1999-2016) :: V10 Spark Plug Fully Blow Out
About a week ago I blew #10 spark plug out of my 1999 super duty. I was able to screw it back in, though it only has 2 1/2 threads now, and was able to put 12 ft/lb's of torque on it. I am driving it around and it is running fine but i am wondering if i am sitting on a ticking time bomb thats gonna blow at a random time, and if so what should i do about it. Should i just run it until the plug fully blows out, or is there an easier and cheaper fix that i could do if i fix it before the threads are fully stripped out. I have heard about Time Serts, but without pulling the head i would be scared of having a metal shaving get down into my cylinder and scratch the hell outta it.

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 an 01 F250 with a v10. Driving through heavy snow in 2013 a plug blew out. Should I expect this to happen again if I do some heavy hauling and should I do something preemptive?
View 14 RepliesFord 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) :: 2000 F250 - Blower Would Only Blow On High
My dad has a 2000 f250 4x4 with the 5.4. he said his blower would only blow on high. I told him it was his blower motor resistor. i thought it was under glove box. he took it apart and said no but there was a little box thing with wires he took off anyway and put back on. I then told him it was under hood below a/c lines. he replaced old one with a new one from auto zone and replaced the pigtail( plug too) fan works on high and a little bit on low very very little when u switch it to medium it stays the same. High works great. So we replaced the fan switch. (Radio was a bitch to remove) and it still does the same thing. I checked all fuses . when I check the plug at the resistor there is power to the center pin it stays on when u switch to low and medium but when u turn high on power goes out( on test meter) is there something I am missing? the blower blows on high even when u remove the plug from the resistor. Is that normal?.

Sunday I bought a 2001 f250/5.4 to replace my 91 f250. I didnt drive it yesterday, but this morning on my drive to work the heater was very weak, it seemed to blow warm for the most part, but was barely pushing air even on high. I flipped it over to A/C to see if it blew any harder and it did. Does the blower motor need replace? if so why does the AC blow harder than the heater?

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?
Ford Super Duty (1999-2016) :: Water In Gas Tank - Blow Compressed Air Into Fuel System?
I am a little skeptical of this, but someone told me that since I got water in the gas tank of my 2003 F250 I should blow compressed air into the schrader valve on the fuel rails to eject it all into a bucket under the disconnected fuel filter.

I had a 2014 F-250 I bought new. Absolutely loved the truck. Things got tight so I decided to sell it yesterday. I'm now looking at a 2005 F-250 with 113k miles. It's got a lift, 37" tires, DPF delete, pretty sure the EGR delete but not sure exactly what to look for under the hood. A ton of LED light bars, SCT tuner, I was told its bulletproofed by a dealer, and it's a king ranch. It runs great. I plan on having a diesel mechanic look it over but here are my concerns. It does have a slight bit of blow by coming from dipstick. Very little. Also a slight oil leak that looks like it's coming from the bell housing so maybe rear seal?

My 2000 F250 SD 5.4 AWD's A/C wouldn't blow cold suddenly the other day. I confirmed the A/C relay (engine compartment, 3rd down from firewall)was "clicking" but compressor clutch was obviously not engaging with dash switch on Max A/C and engine running. When I take of the 2 wire connector to compressor to see if it is getting power, the truck won't start..if I disconnect the A/C compressor plug while running, the engine similarly quits. I have never had another vehicle do this on me before..I could unplug the compressor on my Jeep GC, for instance, measure 12+ volts with A/C ON w/car running and no problem with Jeep engine turning off.
I have searched for A/C wiring schematic w/o success. I checked every fuse in cab/engine for continuity since I don't know which ones might deal with A/C..jumped hi/lo pressure switch connectors with engine running/A/C ON w/o compressor clutch engaging. Clutch turns easily, have banged it a few times, and air gap looks good. More bizarrerly, I hooked the compressor to a 12V/ground via its 2 male prongs and didn't get the clutch to engage.
Ford Super Duty (1999-2016) :: Spark Plug Blow Out - Few Aluminum Chips Don't Get Removed From Cylinder?
I need to tap a bigger hole and put in an insert for the spark plug. I can see that the piston is far enough down so that it won't get harmed from the process. But if I don't get the intake and exhaust valves shut, and then use compressed air to blow out what chips I can, and then I start the engine for a few seconds to blow out anything else (with the coil unplugged of course) will a few remaining chips, along with some that may have gotten blown into the intake, be a big problem? It's an aluminum head, so I can't see the chips doing much damage before they go out the exhaust or end up in the oil filter. But I am just guessing. I don't have the tool to test when all the valves are shut. Also, is it possible that a valve might be in the way and get damaged from the tap?

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.
