Ford Super Duty (1999-2016) :: F350 - Heater Blower Runs When Ignition Switch Is Off

The heater blower in my 1999 F350 continues to run after the switch is turned off. I checked the relay and it is working properly. Looking for a wiring diagram showing the control circuit for the blower?

Do the heater switch controls power to the relay coil or if the switch grounds the coil to pick up the relay?

Ford Super Duty (1999-2016) :: 2000 F350 - Key Off Heater Blower On / Passenger Airbag Light Blink

My batteries drained twice and now I prob. need new ones but with the key off I can turn the blower on any speed and the passenger airbag light blinks. I hear the clicking from a relay under the dash when I do this. I have checked for leaks in the windshield and found none . The fuse box and the GEM are completely dry. My ignition switch will pull out with the key in it . I noticed this just the past few weeks . Now yesterday my odometer speedometer quit. It did pull a code for this. Maybe it is connected maybe not . My odl light is flashing but still works. My cruise doesn't but I realize it is connected to speedometer.

Ford Super Duty (1999-2016) :: 2005 F350 - AC Will Not Cycle / Blower Only Blow On High

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) :: 2003 F350 - 4x4 High Not Working / 4x4 Low Putting The Truck In Neutral

I recently bought a 2003 F350 super duty dually automatic transmission 6.0 deisel 4x4. The 4x4 is not working. with the hubs in auto when i flip the switch to 4x4 high nothing happens.The same with 4x4 low putting the truck in neutral. I can only find 2 fuses using the owners manual that says anything about 4x4 and both of them check out good. Also the owners manual says when i turn on the key I should see a 4x4 light and a low range light momentarily. Neither of these lights are showing up. I don't hear any clicking or any noise of any kind when trying the 4x4.It acts like an electrical issue but not sure where to start.

Ford Super Duty (1999-2016) :: 2009 F350 - All Electronic Features Not Working

I have a 2009 F 350 6.4, fully deleted with a Mini Maxx Tuner , CAC pipe, and CCV mod, other than that the truck is stock. I have put 100,000 miles on the truck and haven't had any real problems but recently that has changed. My 4x4 doesn't work, Traction Control is gone, Tow Haul mode is gone, Cruise Control gone, basically everything controlled by a button is now gone.If it was one of these issues and not everything at once I would check for fuses, broken wires, etc... But, everything stopped working at once. Not having traction control or cruise control, but I tow heavy all the time so tow haul is a must as it's the only thing that engages the engine brake.

Ford Super Duty (1999-2016) :: 2009 F350 - Stereo Stopped Working - Upgrading?

I have a 2009 f350 xlt with sync and steering wheel controls that the stereo quit working on and I want to replace and I am having trouble finding the correct one that will work with sync. One of the local auto wreckers has a 2010 f350 lariat with the touch screen that they are willing to let go for a reasonable price. Will that head unit work in my truck without major wiring?

Ford Super Duty (1999-2016) :: 2001 F350 - No Blower Motor / Just Defrost

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?

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?.

Ford Super Duty (1999-2016) :: 2012 - Blower Motor Not Working?

2012 F350 Lariat 6.7

The blower motor has quit. All fuses relays etc appeared to be ok. So I tested the connector going into the motor, I saw 13.9 volts so assumed it was a bad motor.

After removing the motor I bench tested it by connecting 12volts to one side of the connector and negative to the other. It spun up.

I re-tested the motor supply connector in the vehicle, it has 13.9 volts on the yellow wire, and 4.44 on the other. I adjusted the fan speed on the climate control, although the fan images on the display increased, there was no change to the voltages on either line.

I used the 13.9v connection on the positive terminal and a ground on the negative, the motor spins.

Is there a method for accessing codes that will display what is causing this failure?

So why do I have 4.44 volts at what should be a ground? Is this a bad resistor or is the climate control euchred.

Ford Super Duty (1999-2016) :: 2001 - Suddenly High Idle / No Blower And Hard Shift

My '01 recently seized up and a buddy determined it was the AC pump. Replaced the belt with the bypass version. A month later, I moved across the state to Iowa. A couple weeks into living here I turned the truck on and it was idling really high (about 2500-3000) but would settle down to around 1100 when put in gear. However, shifting into gear is causing a progressively worse "jump" into gear. Hadn't really had the money or the time to take it in so I let it mostly sit unless I absolutely needed the truck.

Today, the idle is still high and does seem to cycle a bit in that it will rev up close to 3000 then settle back down around 2200 or so and then rev back up again and so on. I backed it down the drive into the sun for a little warmth and it darn near jumped a foot when I shifted. I turned the heater on defrost so I could clear the windshield and absolutely nothing came out.

I can't get into a garage for a few days to get it hooked up for diagnostics. So I thought I'd try here. My research leads me to think part of my problem may be a vacuum leak and/or maybe a sensor somewhere.

Ford Super Duty (1999-2016) :: AC And Heater Fan Working Intermittently

I have a 07 F650 crewcab with a Cat engine. The air-condition and heater fan work intermittently no rime or reason to it, be driving down the road and it quites, then maybe a few hours later and it will start. A few days ago my wife turned on the key and the fan was working and then yesterday she turned the key on and it wasn't. When I bought it I watched them replace the fan and it worked for a few hundred mile then stopped, for the rest of the trip it was on and off. I replace the resistor and spliced on a new electrical connector, but still have the same problems....

Ford Super Duty (1999-2016) :: 2000 F350 - Gas At High Altitude

I've got a 2000 F350 crew cab with a camper I bought in Chile and I'm going to be driving it from the tip of south america back to the US. It's a 9 month epic family road trip. It'll involve crossing the Andes several times and going over 15,000 ft. There are roads up to 19,500 ft in various places.

My question is am I going to have problems with the altitude? What can i do about it? I've got another truck which is a unimog, it's slow as hell but has a special kind of booster gas you can inject in to the engine to get it started in very cold weather and at high altitude. I chose the F350 for the truck instead of the unimog because a unimog is slow as hell (think 40mph max speed), but it handles extreme conditions well.

Ford Super Duty (1999-2016) :: F350 Missing At High RPMs

I have a miss at high rpms.. I pulled this engine, manual trans, and 4x4 axle and put them in my F350 Majestic motorhome. 156,000 miles on the engine. Slightly dusted engine with good compression 375-400 (cranking and corrected for altitude). Has a little bit of a long start.

No smoke on start up unless 10 degrees or colder
No smoke when pulling either.

Glowplugs ...Good
GPR... Good
Checked resistance from IDM to injectors ...Good

History of some ether for starting before I got my hands on it. I have AE with the ford enhancement. But I am new to working on a powerstroke and new to AE.

ICP ...new
CPS...new
Oil ....new
EBP...new

Installed a pressure gauge to the drivers side upper port on my fuel bowl:
60 psi at idle
55 psi at WOT 2500-3000 rpms under a load
HPOP stabilized pressure is 2750 @ 40% duty cycle

Truck still misses (semi-intermittently) at higher rpm with a load.

Rechecked codes KOEO: None present

I visually inspected valve movement while running (idle). Did the buzz test when cold.... All injectors sounded the same when tested individually.

Did a cct when not completely warm:
P0266
p0272

Repeated the test at normal operating temperature:
P0266

Torque values on rocker arms bolts and injector holds are good. Fuel quality isn't an issue since this problem has remained for 5 tanks of fuel. What I should do next?
