I am getting a whistling noise from the dashboard area of my 2006 Ram when I hit about 55 t0 60 mph. It is very annoying, but it goes away if I roll the window down a little bit. Any thoughts? Thanks

 

Could be air escaping from a door or window that is not sealing right?? Or check to make sure that your rear window is closed all the way. I had a whistle in my drivers door and I had it straightened, problem solved.

with your window closed check to see if you have the whistle with the fan on and off? Just another way to see when it us under a different pressure.

 

Back window is closed tight, doors also seem to be tight. Noise happens with fan on or off. It seems to be originating from the upper part of the dash concentrated mostly on the passenger side.

 

A/C? is it like its coming from the defroster or anything or just a whistling noise.... could be hole in the firewall...but doubt it

 

Is it a whistle or a high pitched buzz? I was getting a noise like wind blowing across a wooden reed (buzz?)but couldn't figure it out. Happened at 70 mph with a head wind but in the location you are speaking of.

 

Do you have the tow mirrors? Before I got the tow mirrors-- no whistle. After, that one on the passenger side whistles.

 

I think I figured it out....the sound appears to be coming from the top part of the windshield. If I press the windshield near the top the pitch of the whistle changes. Now I just have to get it fixed, it drives me insane. Thanks everyone for your responses.

 

My passenger side just started whistling and its annoying as hell when your going 60 mph, Im thinkin about putting a piece of tape across where the mirror meets the door where it seems to be generating the sound, DAMN it PISSES ME OFF, lol She started doing it after i gave her a good bath, want an ungrateful B*TCH

 

That is where my brother-in-law thought he heard mine. Next time I'll have someone push on the seal.
