My truck started to make a weird noise about a month ago so I took it into the dealer and they couldnt find anything. it only makes the noise about avery week or so. it makes like an air rushing noise or like air is blowing kinda grinding noise. anyone know what this could be?

 

Sounds like you have a window that's not shut all the way.

 

No, thats not what it is, its coming from the front of the truck. Does anybody else have any ideas?

 

Might it be that supercharger you added? . Just kidding.

 

I think I had something similar the other day on the highway. It sounded like exactly how you are describing it. I pulled over on the highway and looked under the front end of the truck. All I saw was lots of water dripping. I'm guessing it was from the AC. What kind of truck do you have and what year?

 

it's a 2010 f150 xlt, I got the truck in april and it didnt do until about late october or november. I called one dealer and they said it might be the vaccum line but when I took it to another dealer they checked it and said it was fine so I dont know.
