Ford Super Duty (1999-2016) :: 2008 F250 4X4 Not Working All The Time
Mar 21, 2013
I have a 2008 Ford F250 with 6.4. Having alot of problems with the 4X4. Went to put the truck in 4 wheel drive one day and noticed the light on the dash never came on to engage 4X4. Of course we had a big snow storm coming and I didn't have 4 wheel drive. I drove the truck across town and decided to just try 4x4 again and it worked that time. I got the light on the dash and could hear the transfer case shift motor engage. Came out a little later and tried it and it wasn't working again. Took truck to shop where they replaced transfer case shift motor with a remaned motor from oriellys.
4x4 worked for a few weeks then just started doing the same thing again. We thought maybe that motor had problems also so had it replaced too. Truck is still doing the same stuff. Sometimes it works sometimes it doesn't. Figured out that if its not working and I leave it in 4x4 and unhook power to shift motor then plug it back in it will engage 4x4. I've seen some post on here but sounds like everyone i've seen their motor just stops and doesn't work at all.

My father-in-law has a 2008 f-250 with the 5.4. as he was driving a while back all the gauges of the dash quit. The engine still kept running without any noticeable difference but when he shut the engine off and tried to restart, it wouldn't even crank but the security light was flashing. He tried starting it again a few hours later and it started just like normal and ran fine.
He has had this problem occur several times in the last few months, but the other day it repeated the problem again and would not restart for about 5 days. He has tried charging the batteries, changing relays, checking all fuses and finding none blown, scanned it with his code reader, and checked the steering column for bare or rubbed wires.

Actually a couple of questions. I've had one oil change in my F250 6.7. Getting close to the second one. So, my question is, what is the computer using to decide when to tell you that you should change the oil? And, if you changed to a synthetic oil, could you go longer between changes? And, if so, would the truck's sensors be able to tell the difference in the type of oil being used?

My 2005 F-250 6.0 liter Diesel FX4 Lariat is blowing AC through defrost only all the time. I have manual locking hubs and when I engage 4x4 it works perfectly through the ESOF switch. So I am assuming the vacuum pump and lines to the hubs are in good working order but there is possibly a cracked line or fuse blown? I've only had the truck for 2 days and it just happened after purchase. I'm a little unfamiliar with checking vacuum but have done reading and I believe I can do it. I am going to get a manual hand pump and pump to 20lbs and loss shouldn't exceed 1lb per minute. I just need to know which direction to look. Everyone else had their 4x4 not working and I seem to be the only one posting that has ESOF 4x4 capability when the defrost only issue is on.

I have a 1999 F250 Superduty with power tow mirrors. Both mirrors are having this issue. It seems both motors moving the mirrors are trying to run at the same time. I tried replacing the control switch since both mirrors are having the issue, but got the same results. Holding the switch to move the mirrors out causes it to move down and out. Moving it in and it goes up and in. I know from experience with electric on a vehicle that when funny things happen, its usually because it lost the ground.

The tach in my 01 F250 PSD has become intermittent. It works properly some of the time, not at all some of the time, and jumps up and down some of the time.
Does it get it's signal from the CPS? It has a blue CPS that's about a year old and the truck runs fine?

I have a 2013 F350 Lariat. Recently, the backup camera has stopped working about 1/3rd of the time. When it doesn't work, a yellow triangle icon appears on the screen with " Camera unavailable. See dealer." The dealer has checked it, twice, and is unable to locate the problem.

My 2005 Ford F250 6.0 diesel CLIMATE CONTROL DEFAULTS TO DEFROST mode all the time now. For some reason I'll turn on the AC and it is either already in defrost or changes to it no matter what I do. Is the head unit in the dash the problem or is it a vacuum leak or an electrical issue?

I just bought this truck,2013 f250 CC Lariat 4x4. The sliding rear windows opened and closed 1 time and has never done it again. I have read about the motor and cable setup breaking and needing to be replaced. I do not think that is the issue. I have also read that the channel the window runs in needs to be lubricated on a regular basis. I was going to try that first. What is the recommended lube for these window channels?

My light on the overdrive is not coming on and the overdrive does not seem to be working. I had a new transmission installed a few weeks back. Wasn't working prior to this.

2000 f250 7.3. Today I tried using the 4x4 and no light or anything. Here is what i have tried so far. Swapped the relays and also swapped them with the towing relays with no change. Not getting any voltage to the t-case shift motor at the selector switch testing between pins 2 and 3 there is 4.3 volts with switch in 2wd 2.4 volts at 4 high and 1.09 volts at 4 low. Where to go from here? it worked fine 3 days ago.

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.

1999 F250 V10 gas. I changed out the fuel pump, and now the gauge doesn't work. Checked all fuses - they're good. Is there any possibility that I could have accidentally pinned the float under the pickup sock, or got it hung somewhere? Is this a common occurrence? Don't really want to drop the tank again - but looks like I will have to in order to check/fix.....

My A/C has been working fine up til the end of last season and getting worse now. It comes on and blows really cold, then after a bit a electrical connection gets hot and looses contact somewhere. I can turn it off for about 5 miles then turn it back on, May last the rest of the day, may only last 10 min, then turn it back off, wait 10 min, turn on, does great! I thought it might be a dampener door,, but does the same whether in defrost, regular A/C, or max, so I think it has got to be a electrical connection getting hot and loose.
2004. F250 FX4. 198,000 miles,,,, runs great,,, just a little hot driving!!!

I have a 2001 F250 with 7.3.... We swapped the auto for a zf6 manual.... We left the auto's shift position sensor tied to the frame and left in neutral. I did install a pcm from a manual transmission pickup. Also have the clutch position switch hooked up. I have an Edge Evolution CTS2 reprogrammer, and on the display the gear indication always shows P. I suspect that is why my cruise doesn't work. For interests sake, I tried manually adjusting the shift position sensor through all gears, and the reverse lights come on when in reverse but the Edge's display always shows P. My question is with a manual transmission, how does the pcm know that it is in gear? The only sensor that I am aware of is the reverse sensor on the zf6.

Every time I apply brakes I hear a weird humming noise, as well as no stopping power. Checked fluids and pads and everything is where it should be. I heard abs can cause this but not sure on that. I know my master cylinder has a very small leak but it hasn't lost any fluids of that sort. I'm lost. I don't know where else to look.

So my dad just bought a 2008 f250 xl with a single cd head unit and mp3 hookup. When you press the aux button on the head unit, it displays ' no aux audio". We have tried unplugging the radio and plugging it back in for a few minutes, but that has not worked .. Any way to get the aux input to work?

Pump works fine. Replaced pvh. Won't go into 4wd hi or lo no matter what I try. Even with them in lock. How do I know if hubs need replaced or just hub locks?

I just got a 2008 Ford F250 PSD 6.4L and there is an oil leak that seems to be coming from somewhere in-between the front oil pan and the oil pan closer to the back. Where this is leaking from and how to fix it.
