Ford Super Duty (1999-2016) :: ABS Light Is On / AC Not Working And Interior Lights Flickering
Jul 30, 2015
I have a 2006 F250 6.0L Crew Cab 4x4 that started acting up. It started two days ago when I noticed my windshield wipers were only working at one speed. Then today my wife took the truck to work and she said the radio stopped working on her way to work. Then she gets in this afternoon and the ABS light is on, the A/C isn't working, the windows are super slow and the interior lights are flickering. She isn't home yet so I haven't checked the fuse block. Where would you start looking?

I have a 2012 F250 and am having a problem where the interior lights wont come on with the dash switch or when the doors are opened. I have confirmed that it is not a bad fuse, also the lights will come on when the switch on the individual lights is manually pushed, but not automatically like they are supposed to. I dont see it being a door switch issue because the door chime comes on and the stereo goes off when the doors are opened after turning the ignition switch off. I've read that the dealerships will switch out the BCM. I thought maybe the dimmer switch next to the headlight switch but there is no power to it whatsoever, which also I can't dim the instrument panel lights. What did you do to resolve?

Just got a 2001 F-250 Super Duty (crew cab, long bed, 4x4, 7.3L turbo diesel) and have been going through and fixing a lot of little issues. The one that now has me stumped is the interior lighting circuit (which is also the bed light). Here's what I've got so far:
Map/reading lights work, but dome lights do not (neither automatically nor when turning them on via the dimmer switch). Verified all fuses in the PDC as well as the interior fuse panel (behind the driver side knee panel). The interior lighting relay was missing, so I purchased and installed it.
Relay #1 (interior lighting), fuse #4, and fuse #14 are all good - when I pull the fuse with the door open, the relay clicks (and clicks again upon reinstalling the fuse). With the doors closed, the relay clicks when activating the interior lights via the dimmer switch.
The LT GRN/YEL wire is hot, and all related accessories work (map lights, engine bay light, etc).
The BLK/LT BLU wire is not receiving power from the relay from what I can tell.
Before I start trying to pull out the fuse panel to start checking connectivity, anything else to check? The ground at the rear driver corner of the cab is good, and a visual check of the harness running down the driver side of the cab has no visible signs of damage.
Also, given that the relay is audibly actuating the way it should, I'm guessing that the GEM can be ruled out as a possible cause? My next step will be to get a pinout diagram for the relay and crimp a quick jumper to see whether or not it's simply a defective relay... But I doubt it's the case.

Two nights ago I got into the truck at night and realized the interior lights don't come on. I tried the rocker switch it will only dim the dash gauges now. It did work before guessing its a bad rocker switch. I can turn them on manually front and back....

Troubleshooting a problem with friend's 2000 F250. His power windows aren't working and are causing problems with his door locks and interior lights. When he tries to use his drivers side power window, his power door locks quit working. If he puts the switch to raise, the interior lights flash. From what I've read, it sounds like the GEM to me, we've inspected the wiring and it all looks good. I pulled it out today and it looks good inside, no sign of water leaks on it. If it is the gem, how much do they cost and do they require programming?

So my truck drove great to ocean city MD this weekend. Power is perfect again, feels really tight. But now I have having to additional problems.
1) My alt light had been flickering a couples times a month. Last night it came on and stayed on. Lots of threads about this I Know!
I am hoping that cleaning and tightening the connections will do the trick since the alt is a Bosch with only 25k miles or so. But I want to order a rebuild kit:
is my alt a 3G or a 3G8429?
F SERIES | Alternator Starter Rebuild Kits
2) I started to have a ticking at idle. Its very regular and sounds like its coming from the passenger side valve cover. In random threads I have read about timing chain guides breaking and loose rocker arms.
Most of the time its 3 ticks in a row and then a pause. Should I be pulling the valve cover? Think I need to R&R the timing chain? I will post a video later!

Purchased a new 2016 F250 Diesel. When you shut the truck off or open any door while the vehicle is parked, the interior, markers, and bed lights all come on. I know it is suppose to be a convenience but to me it is a pain. And to make matters worst, they remain on for a short period of time after you leave the truck and close the door. Sometimes you don't want the lights to come on, like when you shut the truck off and are waiting to pickup someone. Any solution for this problem, short of removing the bulbs, or reprograming the computer?

I'm not just reposting it though. I went ahead and sprayed all of the door switches with WD-40 multiple times, and the interior cab lights still come on. So, I'm assuming one of the switches in the doors is bad. Only thing is, I don't know how to figure out which door has a bad switch. Any way I could check this? Or it may be something other than a bad switch. It's annoying not having any interior lights (I took them all out to keep the battery from running down).

2008 F 550 6.4L Diesel 2wd... Truck has a few interior elect systems not working. ALL fuses are good. Message center not working at all, HVAC fan not working, key/lights chime not working, and radio lights very dim. All of these problems started at once. Everything else on truck works fine.

I have a 2005 F 350 with a 6.0 Diesel! My heat quit on my wife and I the other night! I replaced some fuses and started the truck to make sure the heat was working and it was! So I thought while I am here I should replace some bulbs in the cluster that were out!
I took the cluster out, looked at the bulbs and they looked oK so I put them back in and put the dash back together! When I went to start the truck once I turned the switch on my gauges and lights started flickering on and off fast and all it will do is just click when I try to start it! I just had it running 15 minutes before this!
I went through all the fuses and if I take one of the relays out and turn the switch on all the lights and gauges seem to work right but when I try to start it, nothing! I replaced the relay and it starts flickering again! I had the relay checked at Napa and they said it was good! The relay was for the Powertrain module!

I have a 2012 F350 and the interior lights and cargo light do not turn on when I open my doors. The maps lights work if I manually turn them on. Why this happens and how to correct this issue?

My prob started with key in ignition warning alarm working with no key, then radio on off at will and interior light not working or delay not turning them off when door closed. Now all gauges and warning lights/alarms go out also. If I open door and key alarm is on all systems work at that moment and without touching truck alarm can stop at will, at that point ignition alarm, interior light, radio and gauges do not work. When I giggle key with truck running the door ajar alarm activates when system working!

The rear tail lights on my truck have been out for a while now. I wasn't doing much driving at night so it wasn't much of a bother but the new job is getting me home a little later and having to drive with my hazards on is getting old fast.
My radio wasn't working either and I disconnected it a while back hoping maybe it had something to do with my lights shorting out but no luck. It remains disconnected. Just in the past few days my front running lights have went out as well.
I've tested all fuses multiple times (and replaced a couple of them) and checked and replaced bulbs. My brake lights, headlights, dash lights and hazards all work fine. I have the trailer light hook up on the rear bumper and disconnected it at the wiring harness as well hoping it was the problem but it wasn't.

I have a problem with my F250 2006 6.0L. I cant seem to get my both fog lights to work. i checked both bulbs are good. I checked fuse 43 an its good. When I turning fog lights on I see a small light that turning on in the panel but the fog lights outside are off. I hear the sound of the relay when activate the switch but I DONT have 12volts + in the fog lights outside? They worked several days ago but not today

Last week I noticed my fogs stopped working. So I figured there may be a chance that they were burnt out. Hooked them straight to a battery and they work. Next I checked power at the plugs and no power. Checked the fuse and blown. The only fuse I had on me was a 25 amp fuse. Big mistake. Smoke started coming from the fuse box (palm to the forehead). Well it didn't blow the fuse but still nothing. I got power at the headlight switch and started tracing wires. From what I had read there is relay but it is inside the fuse box? Is this correct. I'm trying to pin point where the problem lies. There aren't any burnt up wires behind the fuse box and now I'm at a loss.

1999 E-350 Super Duty (figured the problem would be the same for van/truck)
Problem: Backup lights don't turn on when in reverse.
Diagnosis: Changed the fused (because it was bad) but didn't fix it. The bulbs are both good. Brake lights, turn signals all work. I understand the backup lights are connected to the Neutral Sensor Switch. To test to see if the NSS was working, I put the van in Reverse and cranked... Van didn't crank (and likewise for D, 1-3).
So I guess the Neutral Sensor Switch works. The fuse works. The bulbs are good. Haynes doesn't have much as far as troubleshooting for this issue. What should I look at from here?
