Question Loud whistling noise

We're getting a loud whistling noise in our new-to-us 2005 Allure 470 beginning at around 35 mph. Seems to be coming from the passenger side - perhaps the windshield or defrost vent. Could be originating from another area but we have to work on pinpointing that. We can't imagine driving hours listening to this noise - it would drive us nuts! Any guesses from other Allure or CC owners as to what might be causing this?

If no one chimes in with a cause, in order to find it, use electrical tape or good masking tape to tape over seams,joints,and things that may be causing the noise. This method is good for finding wind noises if they are caused on the outside. Apply the tape in steps then drive when the noise goes away....well cause found.
Good luck

Check the windshield rubber seal carefully, it will whistle if it gets out of place.

Don't have the same brand coach, but I had a similiar situation on the driver's side of our Revolution. Discovered that the wind/whistle noise came from one or more of the "weep" holes at the bottom of the window. Covering them with black electrical tape eliminated the whistle. One note of caution if you find this to be the source: remove the tape when washing your coach or driving in the rain. These holes are intended to allow normal water draining off and around the windows to escape.

Please let us know what you discover....it will help others. Thanks....

We had such a noise at the door frame. Replacing the door insulation solved the problem.

In our coach, it turned out to be the gap between the fiberglass panel covering the slide out gen set frame and the fiberglass panel covering the remainder of the front of our Inspire 360. We used some sticky foam to run along the entire inside where these two panels come together. Fixed it. You can troubleshoot first by simply applying masking tape along the entire gap along the front of the coach. If the whistling stops, you found your source. Our whistling always started about 40mph on got louder as we drove faster.

Try spraying lubricant like WD40 on the seal in the door frame. It is true the windshields can spring an air leak too. I like the tape idea. But try spraying the door seal first. Our coach had a whistle when we first got it four years ago. That is what I did and it fixed it for good.

VERY CAREFULLY inspect the seal around the windshield.. I'd bet that your windshield is startring to separate from the RV, now it may be the glass separating from the rubber, or the rubber from the fiberglass.

I have that problem as well.. Was going to look at it this stay, but it will not happen (ladder occupied with other tasks) Perhaps in 3 weeks.

Home is where I park it!
