I have a 2008 F 150 Super Crew. I have a noise that increases with speed. It is a buzzing noise that appears to be coming from the cowl area. I have replaced one of the cowl retainers which made no difference at all. I also have driven with the passenger wiper arm removed. I am pretty sure the noise is coming from that side of the vehicle. The noise starts around 50 and reaches a peak at about 70 mph. The cowl is looser fitting on the passenger side but I can't tell if that is the source of the noise. Has anyone else encountered this problem? Any help would be appreciated.

Thanks,

Some folks here have reported getting some weird noises from their antenna. Try removing it & doing another test drive.

 

I mentioned the antenna a couple of days ago and he never replied. He started a new thread with the same complaint instead...

 

Ok thanks I'll give that a try. I have noticed that I do not hear the noise in rainy travel.

Thanks again,

 

I'm sorry I missed your reply the other day. For some reason I could not find the original post. I have taken the antenna off and still have the noise. Does anyone have any other ideas?

Thanks,

Hmmm...In the middle of your dash, kinda' towards the top is this little **** marked "Volume". Turn it clockwise until the noise goes away.

No more ideas, sorry.

 

I can drown it out some but it it's still there. Thanks for your help anyway.
