Have a 2012 350 cclb 4x4 6.7 lariat, interior lights don't work. Not with any door open, Not with switch. map lights work. We've checked every fuse in cab and under hood. What to check now ?
View 8 RepliesI 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?
View 1 RepliesI 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?

View 6 RepliesPurchased 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?
View 13 RepliesI'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).
View 6 RepliesI 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?

View 1 RepliesJust 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....
View 5 RepliesThis morning on my way to work in my 2012 F-250 I turned the heater on, controlling the temp from the temperature control. When the truck got up to temperature the heater fan would not come on accordingly to bring the inside of the truck up to the temperature that I had selected on the controls, so I tried operate the fan manually and it still didn't turn on. Once at work I didn't have really have time to look at anything with it, I did however shut the truck off and start it again and still nothing. Then after I got off work, driving home still nothing until I was about half way home then all of the sudden it started working again. I'd sure hate to have this happen again later this winter when the temperature gets below zero outside.
View 3 RepliesI have an 02 f350 XL. The other day it rained and all of my rear lights went haywire. All problems are out back.
- Step on brakes, high mount, and lic plate lights light up with brakes.
- Turn on marker lights and the high mount lights up and the tails and lic plate lights dim.
- Marker lights on, apply brakes, and the tails and lic plates lights go out on bed, high mount activates.
- Use turn signals with markers off and all of the rear lights including high mount flash..
- Reverse lights dim or dont work at all.
I have tried a new MF switch, checked all fuses. cleaned rear frame ground. took apart brake switch and cleaned it. non tilt column but checked wires. replaced flasher. unplugged brake light switch and headlight switch, problem is still there. removed trailer relays, no luck. checked all chassis plugs. disconnected TRS.
I should mention i have 12v cummins swap and a pcs with standalone harness. no problems over the last few months since swap until it rained last monday.
Do the raptor style boards will work on an F250, 2012?
I hate the stock ones and want something closer to the body and has some rocker panel protection. Alternatives are welcome but not 1k ones.
I screwed up installing LED taillight assemblies in my 2011 SuperDuty and pinched a couple of wires against the body. The result of this (at least I think that this cause) is that my backup lights no longer work - neither the backup lights in the tail light assembly nor the reverse light power on the trailer plug. I have checked the fuses, etc. and nothing. I brought it to a local shop and they could not figure out the problem, either, but said that it was probably the "control module" that got fried when the wires got pinched. They said to take it to the dealer. The questions are, what "control module" might they be referring to, or what to check?

View 5 RepliesI have a 2001 f-250 that has dome lights that work on occasion. Mostly don't work. The inside dash dimmer won't turn them on. And they will sometimes work with the rear doors opening. Not the front(4 doors). The cargo light comes on all the time. So I don't know where to start chasing.

View 6 RepliesI have a 2012 F-250...per DOT specs, the fog lights go out with hi-beams on. However, in my opinion, the high beams on my truck are among the worst I've seen. Low beams are OK. Is there some easy mod to keep the fogs on with the brights?

I was replacing my headlights, which required me to splice in their lights to my parking lights, and I seem to have shutdown ALL my parking lights. I did a test after twisting my wires together and everything worked fine. Then I soldered and heat shrunk them and somewhere during that process I lost all the parking lights.
I checked the 8th fuse as per the manual (for Parking Lamps) with a multimeter and it checked out just fine.
Figured it was the time to ask the experts on here where I should go from here. Are there some other fuses I could be missing, or maybe some else I could do?
Solved: Bad fuse in the #8 slot in the Power Distribution Box (under the hood, near Cab, driver's side)...
