Sitting in the house, heard a horn blowing and ran outside to find my F350's horn was blowing. When I pushed on the horn button on the steering wheel it quit. Couple of hours later, it started blowing again. Pushed the horn button to make it stop and removed the fuse so it would not start blowing again. Did a forum search, but didn't have any luck. Short in steering wheel?
View 14 RepliesI have 2002 F250SD, The horn just starts blowing by itself. Bump the horn switch and it stops for a couple of weeks. I've looked at the wires to the fuse box and no wires shorting out the horn wire. I read some very old posts but nothing conclusive was ever decided on, just a lot of guessing. The horn switch has always been sensitive.
Somebody said the air bag is warming up in the sun and expanding causing the horn to blow. Somebody said the horn relay, but in 55 years of working on trucks, I have never had a horn relay act like that. I'm told the horn relay is built in the back of the fuse box and it all has to be replaced. Some say the clock switch. I don't know what that is or where it is. I guess inside the steering wheel. Is it hard to replace?
Where do I go from here....
The other day I was checking out my parking aids (they kept saying something was behind me when there was nothing there) and the horn just started blowing by itself, constant on until I disconnected the batteries. Been a few days and just got back to working on it, checked the horn switch in the airbag and it is functioning fine. Hooked the batteries back up, no horn, but after a couple of minutes I start getting little honks out of it, then locked on again. Where I should go from here? Truck was parked, switch off, engine off today when I hooked the batteries up. Never started it or turned the key on.
View 6 RepliesI have a 2005 f350 lariat 6.0. My horn, cruise volume, heat and fan controls on the wheel are not working. The airbag light isn't on. I am thinking that it's the clock spring. The stereo controls were intermittent for a while so I think it's the clock spring. I just want to be sure. Anything I could check?

View 3 RepliesI have a 2004 5.4 power f350 that makes a fog horn pitched howling sound at idle. First instinct was a pulley. Started it with belt off and its obviously something else because it still made noise. Traced it down to a resonating sound from the intake. Specifically the hose from the IAC to the air cleaner.
From some googling, i decided to change the IAC. No real change. So I took off the resonator tube and thoroughly cleaned it, took off the throttle body and cleaned it, took off the top snout part of the intake and cleaned that put in a new air cleaner (the glue was separating on the old one) and reset the battery. Still makes noise at least 85 percent as loud as when i started. Am I missing something?
2008 F350 6.4 diesel. I have the listed truck in the heading, my #9 fuse which is for the interior lighting, lighted running boards and it is a 15a fuse, keeps blowing as soon as I touch the fuse to the fuse box to replace it. I have look at all the map lights and interior lights and can not find any thing out of the ordinary, all of these light were working fine, also my cruise control and the back up sensors stopped working and they are not on the same fuse and the other components that are on the circuit with the crule and back sensors still work, I know that this is a lot of different things but hate chasing electrical ghosts...

View 1 RepliesMy 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 .
View 4 RepliesI was recently on a trip pulling my 32' Travel Trailer, and out of the Hvac system started blowing scalding hot air and soot and smoke into the cab. I pulled over to check things out and could find nothing wrong. When the turbo kicks in it blows even hotter. I could find nothing wrong at the time. As I got back on the road again it started again a few miles down the road.
I made it home and started checking things out. Around the dash, airbag, glove box, on the window , headliner and carpeting, is covered in soot and smoke. the computer is now telling me that ALL the doors are ajar, power locks and key fob do not work, 3/4 of the window switches do not work and 1 window does not work now. I removed the glove box and the panel underneath it to look at the HVAC system.
What I saw about made me cry. The Plastic that houses the HVAC system had started melting and the HVAC hoses have melted. I have still not found the reason for any of this to happen. Also when I got the truck a year ago the Turbo would spool up around 1800 to 2000 RPM. Now it does not spool up until around 3000 to 3250 RPM.

I have a 2006 F350, it keeps blowing fuses for the brake/turn signals. The puzzling​ part is it only does this when the truck is running.
View 2 RepliesI have a 2002 f350 7.3 PS that every time I touch the brake pedal it blows the #6 fuse(trailer tow brake/turn signal). I need to use my trailer.

1) When it rains, I get water dripping in the cab over the glove box. The seal on the windshield looks fine. Truck has a sun roof. Is there a drain tube or something from there that might be plugged?
2) AC sometimes blows very humid air in the cab. It doesn't do it all the time, but seems to be in a cycle. After it runs for a while it switches to this humid mode and gets almost unbearable, to the point that I turn it off. In summer, when cooling, this air is warm. In winter, air is warm, but fogs windows pretty bad. What causes this? Noticed also that the tubes under the hood covered in frost and truck drips water from this area seemingly excessive when I park it.
The truck is an 05 F350 King Ranch 4x4 with the 6.0 Powerstroke
Windshield wipers, and washer were suddenly not working the other day, so I discovered a blown fuse. Put a new one in, and it immediately blew again. So there is definitely something grounding out, and I am suspecting the wiper motor itself because so far I have not been able to find any wires shorting out, but before I go to the trouble of pulling the motor out and testing it, or replacing it.
Truck is a 2002 F350CC 7.3 TD. Wipers were working fine the other day before I pressure washed it, which is why I really suspect the wiper motor itself.
I was driving from home to work the other day and it was 6 degrees out. My heat was working good and everything was fine and then all of a sudden the passenger side started blowing cool air. Not cold not warm. Driver side was still hot. It is a lariat and has dual temp zones. Everything I read everyone says blender doors but what would make it stop working out of no where when everything was fine. Occasionally when I start my truck and turn the heat on it makes a popping noise under the dash when the blower kicks on. But it has done this since I owned it an never had an issue. It's 25 below today and I would really love to have completely functional heat. It's an 2008 f350.
View 14 RepliesIn my new to me 99 F250 SD ,Started today off with switch sticking in drivers door causing dome light to be on when doors closed... oiled the crap out of the door mechanism and it started working. Later in the night I look out side notice the radio lights on with no key. Can't figure it out so pulled the face off and figure I'll look at it tomorrow and go to bed.
1:30 am the horns blaring! I open drivers door and horn stops, close it and it goes off I ended up pulling the batt cable so I could go back in the house. I did search for info with no sure real causes. Seems like it has happened to others as well.. BTW it did start raining before the radio stayed on. Thinking water in the dash or fuse panel. But it doesn't explain door switch problems I had earlier. Maybe 2 separate problems. This will be fun! Not!
Okay so I have an e99 f250 7.3 the problem all started went I hit a puddle the other day. My horn started going crazy and wouldn't shut off so I had to pull the fuse and relay. After that I found another problem, all my dash lights,headlights and running lights will not turn off unless I pull the battery terminals, it does not matter which way the headlight switch is it can be on or off and they stay on. I did find it though if I pull the negative terminals and put them back on the lights stay off if I turn the switch on and try to turn the lights back off with the switch they stay stuck on again untill I pull the terminals what could be the problem I've looked at every fuse and can't find the probelm.

View 4 RepliesBeen searching but can't find a clue. I replaced my steering gear box. Went fine, but after starting back up. My alarm goes off, my cruise or horn doesn't work and my air bag is giving a code 32.
Is there a ground wire or something I could of missed when installing the gear box?
I have a 2001 F250 V10, 150,000 miles, gas, very basic truck (no power windows, no cruise, no security system, no power locks, etc). In it's previous life, it was an IDOT highway truck I purchased at auction in 2005. Used primarily to pull horse trailer, less than 2000 miles per year. Stored under cover when not in use. Windshield leaks very little, but generally not used when raining.
Last week, 9pm, horn starts blaring solid tone. I go out and unlock door, open door, it stops. I start truck, still fine, turn truck off. Lock door, close door, starts blaring again. I reopen door, leave unlocked, close door, then get intermittent beeps. I reopen door, disconnect battery because it's late, I was going out of town, and felt bad for my neighbors. Just got back in town, too afraid to reconnect battery and not be home in case it starts going off again. I had last used the truck about 36 hours before the horn started going off, weather about 70 degrees overnight.
I've read other threads, but can't find one that fits (I have no cruise, kept out of rain, not freezing cold, not diesel).
F250 today at 61300 miles going down the interstate today my vehicle made a strange new noise that sounds like an old timey car horn. The sound started at about 75mph and comes and goes depending on what appears to be air turbulance and other vehicles nearby or goes away as the speed comes back down to lower numbers. Also when the sound is present you can "feel" it in the side handle on the A post. Really weird. Doors were closed all around.
