Ford Super Duty (1999-2016) :: Passenger Low Beam Does Not Work - MFS Shorted Out?
Dec 28, 2015
Was working on a friends 06 F-250 and was trying to wire in some plow headlights. I must have shorted something out and the Passenger side low beam doesn't work. The high beam works and the drivers side high and low work. The fuse under the dash is good. From looking around, is it possible that the multi function switch on the column got shorted out? Any way I can test? Any other things I can check?

I just had my pass side head lite burn out.....or at least I thought? I replaced the bulb twice......not touching either 1 with my fingures.......and I have no low beam on that side? Only hi beam on the pass side? All my fuses are good, and I even unhooked all my plow harness.

I have a 1998 C class RV with the dash Air Conditioning that is shorted out, it keeps on blowing the 15A fuse when turned on to Norm A/C or Max A/C or Mix or Defrost settings on dash only.
For troubleshooting I have disconnected the engine Air Conditioning Compressor plug to verify that it isn't the fault.
I've removed & replaced the switch that controls the dash a/c to defrost settings and worked for a minute, but now continues to blow the fuse as before. I'm not ready to buy another switch for now.
Is there a common item that may contribute to fail or common wiring that I should look at. I purchased the full electrical and service manuals but haven't dived into the ohm checks of the wiring, wire by wire yet. Tight wiring areas under the dash.
Also the fan speed controller works when in VENT or FLR modes, so I don't believe that is the problem, also temperature vacuum controls work.

I recently purchased a 2003 F-250. The door locks don't work properly, the passenger side will lock the entire truck all 4 door locks actually lock. The unlock on the passenger side does not work and neither does the entire switch in the driver side. I attempted to switch the actual switches from the driver to passenger side thinking that it could be a switch that is broken.
After doing that still only the passenger side would lock and the rest of lock unlock buttons did nothing. I have checked all the fuses in my truck and actually took the door panels off today thinking I might find an obvious problem. I know the actuators are a common problem but because all the locks lock in the vehicle I was thinking it might be something else.

I just purchased a '12 f250 Lariat w/ 39k miles. When I got home I noticed one of the three LED running board lights does not work on the passenger side. Can I replace this myself?

I have a 1999 F250 super duty with the V10 engine. I purchased it when it was @111k miles. When I got it the passenger side lock did not always work and after time they both stopped. I have ready the post on how to repair them for little or no money that is not my question. My question Is there a way that I can tell if the truck had a remote for the locks when it was new and if not could I put it in the truck? Yes my wife likes that I unlock her door first but a remote would be nice when it is raining.

I just bought a 2004 f-250 checked everything out except for the headlights ... when I tried them the didn't work except on flash to pass ... I searched around and found some possible solutions and tried them .... first I checked the bulbs and all the fuss they are good then I bought a headlight switch ....that fixed the problem for about two days then they quit working again... so I took it back and got a new one ... when I first put it the new one in it didn't work then it started working a day or so later and I hadn't done anything to make it work... then a couple days later it went out again ... I have swapped the switch out several times and have had no luck I replaced the multi function switch and still no low beams ...
All the fuses are still good I have checked the wiring visually as much as I can see and see nothing... buddy of mine checked the pins on the headlight switch connector they are all good .. Read something last night about a guy whos alternator was going bad and caused his not to work checked mine its putting out around 13.4 at idle .. is there a relay somewhere ... my book doesn't show the function of any of the relays so I don't know ...not a mechanic but a pretty decent parts changer. Trying to fix this myself . Next week have to take the truck to pull the camper ..

All you need to do is pull out the head lite switch find the solid brown wire that is the running lights wire now find the yellow wire this is fog lights wire (these wires are on the gray plug ) you need a 3" piece of wire and 2 blue wire connectors it slips over the wires no cutting any wires then slide wire in the other end of the blue connector after you jump them your fog lights will come on with running lights and will not go off with high beams...

What color wire controls the high beams?

I was cruising my truck down the road and noticed that my high beam indicator light was very dimly lit. I wondered why this would all of the sudden come on at all if the high beams were not on so I pulled over and took a walk to the front of my truck to check my headlights. Sure enough the passenger light was very dim. (I must assume the high beam indicator light being dimly lit is also an indicator for headlight malfunction/burn out)
I figured out the plug has a keeper piece that is supposed to hold it in the bulb base but it was broken off and missing.
I went to the auto parts store to find some kind of fix. To my surprise they have a replacement plug for my truck. The down side is it costs $95 and it still had to be shipped! I decided I could figure something else out.
After I pulled the four 5.5 millimeter screws out of the headlight housing. I noticed there is enough room on either side of the light contacts to drill a hole thru the plug and the bulb to allow a pin to be placed thru both of them which would keep the plug and bulb socket from coming apart.
These are the pins or keepers I used.
A 1/16" drill bit did the job. I put the new bulb/socket and the plug together and drilled a hole on each side of the plug right thru the socket at the same time far enough back and at a width to avoid the contacts of the bulb socket and plug. (there is a rubber gasket in the plug that should be avoided but if you still knick it as I did you can fill the plug or the socket with dielectric grease that most car parts stores have and it will keep any moisture out but not effect the electrical current, do not use silicone, one day you will have to take it back apart for a bulb replacement or something.)
This is the bulb socket with the holes already drilled and the plug removed. This is what it looks like with the bulb/socket and the plug together and the keepers in place. And the back of the composite headlight housing with the assembly installed.
Make sure you install the bulb/socket and plug with keepers on the housing before you bolt the housing to the truck because there is not enough room to get your hands behind the housing to install the keepers with the housing bolted to the truck.
Since I replaced the stock bulb with a Sylvania Silver star I had to replace the driver side too so I didn't end up with a headlight being brighter or "whiter" than the other. Even though I was incredibly careful I still broke the plug on the driver side too! So now both of my headlights now have this mod on them.

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.

Went to hook up my trailer today and both the trailer plugs do not work. I checked the fuses and all is well. They worked fine the other day but now they don't work at all. I confirmed this by hooking up to another trailer and nothing. Also got another truck and went to trailers and it worked.
My truck has 19000 miles so it's practically new. I have never seen this. I called dealer but they can't see it til next week and I need the trailer brakes and lights. Where could I look or what could the problem be?

I recently noticed some electrical problems with my truck. The doors don't auto lock and my truck can be started with a standard key and does not require a chipped key. I tried looking at the setup menu and I noticed that the only menu item is the language selection and that doesn't change. I am not getting codes and my truck is running good overall.

I bought a 2004 F250 SD XLT 4X4 crew cab which was a a roll over. The cab was replaced with a KR cab, its believed this was from a 2 wheel drive truck. My issue, the electric 4x4 does not work on the truck I have to get out and put it on manually.
Also, the ABS light is on the dash is on and the ABS doesn't work. The overhead panel doesn't work either. A friend of mine believes it could be a wiring harness issue but isn't sure replacing it will have any effect on the 4x4 and the ABS.

I have a 2016 F250 6.2 XLT CC 4X4 that is mostly stock, except I did put on 18x9 wheels and LT275/70/18 Cooper ST MAXX tires. I have noticed recently on hwy driving and even in town driving, that the passenger seat rattles/vibrates quite loudly. Obviously if there is someone setting in the seat, it is just fine.
Is this a common issue? Is there a quick fix (tightening a couple bolts or replacing a couple clips?) Or should I take this back to the dealer for warranty?
