4x4 dash indicator light stopped working on my father's 2002 F-350 V10 about 8 years ago and I'm trying to see if I can fix that problem.
Unsure exactly when this problem began, but when a mechanic replaced front wheel hub about 8~9 years ago, automatic hub lock stopped working. Back then, I thought that is why 4x4 indicator stopped working.
When I removed hub to replace ball joint 2 years ago, I discovered yellow O ring was not installed and that was the reason why automatic hub lock stopped working. Now I installed new O ring and vacuum seal, automatic hub lock works. However, 4x4 indicator on the dash still does not work.
I thought may be bulb went out, but when I tested dash bulbs with self test mode, 4x4 indicator light turns on. Also I believe that lamp is LED not regular bulb.
When I pulled DTC, I get P1879 - Powertrain Transmission Transfer Case 2-Wheel Drive Solenoid Circuit Failure. From what I searched this indicates failure at vacuum solenoid for front hub locks, but it is working fine. What is going on?

Question: How easy is it to replace the key switch - do I need any special tools? Is there a way to upgrade to one which requires an encrypted RFID key? Or is there an easier fix to my problem below?
Background: On my '05 SD, I am getting a weird problem where the ignition switch chimes Key-In sometimes when there is no key. I can get this to go away by fidgeting with the key switch, but since I am going to be installing a remote start / security system, I need to fix this...
Ford Super Duty (1999-2016) :: 1993 F350 - Clutch Position Switch Fault?
I'm getting a random 'no start' fault which I think is related to a clutch position switch. The dealer tells me the clutch pivot bushing and master cylinder push rod are worn out, which is causing the switch not to close when the clutch pedal is depressed.

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) :: F350 - Only Passenger Side Switch Locks Both Door?
My power door locks just started acting up. The driver's side switch will not do anything. The passenger's side switch will lock both doors, but it will not unlock them. Is this a switch issue or the actuator? I am assuming the issue is on the drivers side only and am leaning towards the drivers side switch. With that said, I read about a lot of issues with actuators on these truck which makes me think it may be the actuator? Would the doors still lock if the actuator was toast? If it would, why doesn't the driver's side switch work? I tried replacing the driver's side actuator but it made no difference. I also swapped the driver's and passenger's switches and it does the same thing. The passenger locks only and the driver does nothing.

I just picked up my 2007 F350 as a replacement for my 2003 F350 (still have the 2003). I really like the uplifter switch option on the truck, I can normally figure things out but I am one of those people who is electrically challenged (home and auto)and also am one who does not wish to butcher the new ride (same for the home)to gain an education in the art of wiring. I would like to reinstall my headache rack lights on this truck as they are needed for winter work. I was in my truck manual and the info for wiring is weak and the website did not respond nor did my email to ford. I have found the wire harness but it is not tagged as a pair/color to switch. I have the lights already grounded to the rack, so I am thinking I just need the hot wire from the switch. Looking for the color code for positive and ground for the switches.

I picked up a 2014 F350 CC a couple months ago and have finally driven it in the evening. I went to turn on the first row map lamps and the light did not illuminate. I could turn it on with all of the interior lights, but not just a single map lamp. It also works when the door is opened or the RKE unlocks the truck.

2008 F350 when I switch the 4x4 to 4 Hi or low the cluster light doesnt indicate it has switched into 4x4 probably 50% of the time it works 50 it doesnt! I have pulled the transfer case shift motor off tested and working installed a new 4x4 switch, checked the relays it has been to Ford two times last week and once they pulled an error code that says (switch, 4x4 module or wiring problem)! Ford did reprogram the 4x4 module just to see if it would fix it and no change all this leads me to believe its the 4x4 module!?

I have a 2004 F-350 V8. The bed has been removed and it has a small dump body. This is the problem that just randomly started with my lights:
The headlights, dome lights, and tail light illuminate - the rear lights do not illuminate when the headlight switch is on. Otherwise, the brake lights work, the reverse lights work, the four ways work, and the turn signals work.
I checked the ground and believe it to be okay - What am I missing and where do I start?

Ford Super Duty (1999-2016) :: 2002 F350 - 4wd Stopped Working / No Light Or Noise When Turn The Switch
Having a problem with my truck and I'm stuck. About 9 months ago my 4wd stopped working. Turn the switch and no light or noise. I took a look at fuses and everything was good there. I let it go but now I need 4wd. Today I checked every fuse and all of them were good. I moved to the relays checked them and they were good but for the heck of it replaced them. Checked for power at the pins. The one that needed power had power. Next I went to the switch had 12 volts there. Pulled switch and test with a multimeter and ohms were good. Went. Down to the motor and tested for power there not power to the motor. Is there anything else I'm missing Esof not working. 2002 f350 7.3 auto....

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?
Ford Super Duty (1999-2016) :: F250 - 4x4 Light Flashing Continually When Turn The Switch To High
I have a 2010 F250 super duty. I use it for work so I am not sure what happened to it as others have driven it, but here is the issue. When i start it up in 2wd, the 4x4 Low light flashes continually. If I turn the switch to 4x4 high, the 4x4 high light flashes continually. if i turn it to 4x4 low, that light flashes continually. I have read the forums but haven't been able to find the problem/diagnosis for this.
