Ford Super Duty (1999-2016) :: E350 - Backup / Reverse Lights Not Working
Jan 2, 2010
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?

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.

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?

I 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.

On occasion I'll have the reverse sensors quit working. I'll drop the shifter in reverse and the 'OFF' light on the button will illuminate. I took the sensors out and blew them clean with compressed air, dielectric geased the connectors and reinstalled the plugs. Let's see if that does the trick.
As mentioned, it's occasional and nothing in particular will trigger the fault....it's very random. Something tells I haven't seen the end of this problem, but tracking an intermittent fault is tough.

I just noticed a week ago that I don't have reverse lights. I check the fuses all good. I have checked the harness and there is continuity. So that tells me that the relays are good. I also read to check the neutral safety switch but where it is located. After trouble shooting last night I also noticed that I don't have my 3rd cab brake light either.

My daughter came home a bit ago and told me the backup lights on my '02 F350 were on. Pretty odd because the keys were in my pocket at the time.
When I opened the door to the truck, I noticed a faint electrical smell and noticed the fan for the environmental controls was running as well.
I'm guessing the light issue is probably a sensor or something at the transmission but why would the blower be running as well?
Early last week I finally decided to try and figure out why my cruise control hadn't been working and discovered fuse F2.34 was blown. Replaced it and went through the test procedure described here: [URL] ....
No issues and the cruise is working again. I had to take it on a road trip for work the following day and didn't have any issues for almost 1,000 miles.
I drove it last night and didn't have the issue. I drove it again this morning to several places and everything was fine.
I've got a tuner with a code reader. Would something like the above problem register a code?
I've not stuck my head under the truck yet (it's cold and dark out.) What sensors I might need to check out? Is there a testing procedure available to ID the faulty component?
The battery is disconnected for the night, but I'd sure like to get this thing sorted before I hit the road for work again this week.

I love my new truck. '15 250 CC SB. It would be nice if when I am backing up not to have the dash lights in my eyes once I turn off the head/parking lights at night. I turn off the head lights so as to make everything darker. Much easier to see what is in my mirrors.

My 2005 f350 reverse lights just started to not work . So I checked the fuse and it was blown and every time I put new fuse in it blows, where to check. Sounds like a ground issue am I correct .

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 recently bought a van that has a hard shift problem. It is a 1995 E350 with a diesel. If I take off from a stop without babying the throttle, the shift from first to second is very hard. Second to third is hard but not as violent. What might be happening?

My 99 7.3 has had a vibration / shake in cab as you rev up while in park in neutral around 1000 RPM -1700 mostly. Around 1500-1600 is the worst. At idle it seems fine and what you would expect from a 7.3 but then as you give it higher idle, it starts shaking cab and you can physically see seats start shaking and it all feels rough. It also translates to a vibration while driving in those RPMS down the road... It has new injectors, transmission/ torque converter, HPOP, exhaust and a whole lot more.......

I have a 2003 e350 with a 6.0 lt. diesel and an automatic trans. The problem is when its cold there is no power ( 10 mph max ). When it warms up it does just fine. The other problem witch I think is connected is when it shifts I lose all power to my gauges and radio for a split second. I am thinking transmission but not sure.

Looks like a great option the Job 1 trucks missed out on. Looking into the feasibility of it. This is my first Ford so I am not really sure how the factory plans these things out.

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.

I am having a problem with trailer lights and an 03 350. When the truck is in reverse the fuse for travel trailer running lights and tail lights blows immediately. Changing plugs on the truck did not work. Truck has been hooked up to 4 other trailers including another travel trailer with no problems. Our travel trailer has been hooked up to an 08 and a 2011 truck with no problems. Fuse 38 20 amp. 7 post rv plug.

I would like to add a second backup camera to my 2016 F-350 Super Duty to assist when hooking up to my fifth wheel. It is a Crew Cab with the Factory Tonneau Cover so my view of the hitch is blocked. I would like to add the third brake light high mount camera and be able to toggle between my OEM/Tailgate Camera and the High Mount. I have found a couple that claim they will work but both require tapping into the main connector on the back of the display, but not quite sure how to open it up. Accessing the connector is not a problem, just getting it apart without breaking it is the question. The "Lockpick" system has not been tested/certified for the 2016 model.

2012 f250, fog lights stopped working and tried fixing yesterday. I'm getting 12.8v at the plug but as soon as you plug the light in it goes to 0. Ran a new ground from frame and the hot from plug and still nothing. High beams off, truck running and switch pulled out. Bulb is fine, hooked it straight to battery and it comes on. I though it was a faulty ground but by running a separate ground and still nothing. I'm at a lose.

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?
