Ford Super Duty (1999-2016) :: F250 4x4 Engages And Disengages On Its Own
Aug 8, 2013
1999 f250 super duty crew cab 7.3 psd : Why my 4wd is engaging and disengaging by itself? I recently had a vac leak which caused the HVAC controls to stop working and the ESOF stopped working also. I found a creak in the PVH solenoid and replaced it. I also replaced the 2 vac lines going from the hard line down to the hub. The HVAC controls work fine but now the 4wd is turning on and off when ever it feels like it. I have removed the selector button in the cab, disconnected the plug from the PVH solenoid, and even disconnected the vac lines from the hub. The problem still persists.

I have a 02 F250 Super Duty XLT with a triton V8 with a automatic transmission . and when I shift into reverse after driving for a while the starter engages . It does not happen all the time . If i start up the truck and shift through or into reverse it doesn't happen . the only time it happens is when i've been driving for awhile and want to back up or park it will only do it once or twice after each drive so trying to get it to happen while in the shop is almost impossible . could this be caused by the transmission range sensor . I just had the code P0705 (transmission range sensor , A circuit input ) come on but the problem has been happening for a few weeks before that code came up .

I have a 2003 F250 Super Duty 5.4 crew cab. Cruise light comes on when engaged but does not work. I did some research on why its not working checked wiring at the throttle body it seemed ok, Fuse is ok. Also did the self test and everything passed with just one flash but cruise still does not work. I read about many problems with the brake pressure switch but would it pass the self test if that pressure switch was bad? Also what should a switch cost. Local dealer wanted $125.00 for a new one and I have read where they cost around $15.00 - $20.00.

After doing a test drive after installing an 8" lift on my 2000 6-speed manual diesel F-250, I noticed that while the 4X4 engages, it won't shift into Low. I've had this truck 7 years and know the drill: complete stop, foot on the brake, clutch to the floor, transmission in neutral, and it usually takes a couple seconds. I've tried different combinations of backing up first, going straight from 2WD to 4Low, etc and still no 4Low.
As far as I know the ESOF transfer case is all electronic and vacuum doesn't play a role. I don't recall ever seeing a vacuum line coming out of it anyway.

I have a 2004 to 250 super duty 5.4 and automatic trans it has about 233,000 miles on it. Yesterday when I started my truck I could see my reverse lights were stuck on against the garage door in the dark. After I put the truck in drive the lights went out later on I shift at the truck and to park and the starter engaged I put the truck in neutral and it stopped the starter from running after doing that several times the truck now does it even when it's in reverse or neutral. I have to leave it in drive and push the emergency brake on I am in and out of the truck all day long. I did change the shift to blast may I check the screws on the back of the shift to bury thing seems fine.

I am having an issue with a Ford f250, 5.4L, granted this problem existed before and after new A/C compressor, dryer, evaporator, vent door switch, blower motor resistor, new evac and recharge, good pressures no leaks.........Now my problem is the truck runs perfect but when the ac engages at idle the engine bogs down and it seems the clutch is constantly engaging and disengaging........AC blows cold, no issues there, does this sound like an IAC valve problem????

I've got a problem with my AC Compressor, with the AC on the compressor engages then disengages about every 5 seconds. Now I looked into it and some people said you can remove a washer to remove a gap. Do you think I should change the whole unit? Looked online and I can get one for $100. If I do work on the AC compressor to try and fix it or remove the whole unit do I need to drain any refrigerant etc etc. I have a hayness repair booklet and they said that to remove the ac compressor you need to get it drained by professionals. Although on the compressor I only see a electrical plug and no hoses.

Is there a steering stabilizer for a 92 Ford F-250 custom 2wd? and what's the difference between a f250 custom and a f250 heavy duty?

So I just bought a 2016 F-250 (6.2L Gas) and the dealer says the trucks don't have gas caps anymore. Built in vapor lock blah blah blah... I have seen this on some cars, but it looked different. Mine looks like it should have a cap screwed on.
I have 200 miles in and "Check Fuel Cap" keeps popping up on the dash. I'm going to call the dealer when they open today but was wondering if anyone has bought a 2016 without a gas cap.

Whenever I open the door to get out of the car after it locks itself the lock rapidly engages and disengages until I push lock or unlock on the key fob. I hope the actuator isn't going bad. And wanted to see if there was something I could do to fix it before replacing the whole thing.

I'm working on my brothers 99 f250 super duty 2wd. The truck pulls to the right. Here's the list of things I've changed and checked
1. Gear box
2. Tie rods
3. Ball joints (aligned)
4. New bearings and seals
5. Brake rotors and calipers. Front and rear.
6. Rotated tires front to back
7. Rotated tires in cris cross pattern
8. 4 new tires (factory size tires)
9. Rebalanced tires
10. Aligned for a third time.
And the truck still pulls right. What is causing this!

I've had my 99 F250 for about 2 weeks and my SES light came on last week. I took it into AutoZone and they read the code. DPFE sensor EGR etc. The kid behind the counter mentioned something about removing those and saving some money. We don't have any emissions testing. I don't want to take any short cuts really, but if its unnecessary to have than why not delete it. I have the 5.4 and it has 189,000 miles and we did buy the truck to haul the camper so that plays into the scenario also.

Okay, so the truck is a 2001 F-250 Crew-Cab 7.3l PSD with about 300k on the clock. For a while now the A/C would start out okay when you started the truck and it would blow cold for about 10 minutes then it would start to fade away and get hot. Then later it might get cold again. You could turn the A/C off for a minute or so and turn it back on and it would be cold again.
Took it to a shop and they drained the system and recharged it and they couldn't find anything wrong with it. Well, it's still doing it. We were starting to thing maybe it was an electrical issue with the cold/hot switch on the dash until a recently noticed a pattern. If it had gone hot and I got heavy on the accelerator (revving above 2500 RPM), it would get cold and keep blowing cold for 3-5 minutes. So the trick to staying cool as of now is just to hammer down every few minutes.
I read the HVAC FAQs, and it seems like the issue maybe with a slipping compressor clutch. Sound right? Also if that's the issue, it says the solution is: Excessive A/C clutch gap due to clutch wear. Usually, the problem can be resolved by removing a shim from the clutch to bring the gap back into the desired .014-.030 gap. What exactly do I have to do? Where and what are these shims?

Ok i have a 99 f250 with a 6.8 v10 that is not turning over at all. I have checked the battery and its good. I have replaced the starter and the starter relay and have tested the starter and its good too. I have also used a volt meter on the batter, starter, and relay and looked at the relevant info and they are all in the correct volt range. I have also taken the starter off and looked at the flywheel and it has good teeth so thats not an issue. I am completely stumped now as to what it could be?

Friend's truck started shifting wierd the other day, starts in second gear (maybe higher). The transmission is a fresh rebuild, the shop wouldn't warranty the rebuild and blamed electrical problems outside the tranny. Fuses are all good, engine light is on but the cheapo code reader won't show a code. Did a search and no answers. Had the overdrive light flashing from before, that code was for a wheel speed sensor.

So, currently I have a 2006 6.0 that's been bulletproofed with a 4.5" lift, 35" tires, and a few other things. I've debated going to an Ecoboost F-150, but I really don't want to give up the payload and towing capacity of the F-250.
The big gripe I have about my F-250 is dealing with diesel issues in the winter and the stiff ride and wouldn't mind a little quieter engine. Besides that I love the big truck. My question is if the 6.4 or 6.7 trucks are better about not gelling and not starting in the winter compared to the 6.0? I've read that the ride quality on the 6.4 and the 6.7 is much better than the 6.0 truck.
I've actually debated just getting a dually F-350 and getting another car to drive when I don't need the truck. I'd never have to worry about too heavy or big of a load and then wouldn't have to worry about driving a big truck into tight places either.

Seems recently my 2008 f250 diesel wants to go into 4wd all by itself. It's the electric switch on dash with the auto/lock front hubs. I'm thinking either the dash switch or the accuator motor. Where to start though... Also I can turn the switch to 4 wheel high and it doesn't go in.
