I own a 2003 f250 superduty v8 gas. I have a buzzing noise that comes and goes. It comes from the dashboard area around the steering column. However it goes away when either I press on the brakes, hit the signal or press my tow brake control.. And I could go days and not here it then it will be there for a few days and then it goes away again...

Thanks

I have the same issue. I searched for "buzzing" and found a few threads related to relays under the dash and possible loose connectors to relays under there. I followed mine and the buzzing is located somewhere just alongside where the 4x4 shifter is. I need to figure out how to get to them.

 

Def sounds like a relay... Just need for it to warm up so I could work on it... But its funny how it sometimes goes away for days or even more.. weird..

Yep. Same here. Sometimes it will buzz non stop. Other times, not a peep.

 

I have this issue too...although it seems related to the ventilation system as I noticed today that if the wind gusts the tone will change slightly if it happens to be buzzing. Wish I knew how to take the dash top off so I could see in there...

 

Think I found it! Hope my research helps others...

The sound is like a "kazoo" sound.

Here is a link to something I found on another forum with an example of the sound. His intensity is MUCH worse than mine and a slightly different tone...but it is the same sound.

This is how one guy fixed it...silicone bead around the windshield. Gonna do that today.

OK...entire lower part of windshield has been beaded with silicon. We'll see if the kazoo returns!

 

OK...a week and no kazoo. Calling this one fixed. Ford should be ashamed of their shoddy windshield install.
