2011 Itasca Ellipse Wind Noise

[MikSher]

My new 2011 Itasca Ellipse generates significant wind noise on the drivers side front corner of vehicle. I have observed that the noise level is clearly a function of MH speed, wind speed and wind direction relative to MH. I see no evidence of wind entering cabin, only noise. In researching this I have found the most likely cause is the drivers side mirror location. Any experience with like issue and corrective action.

I had the same problem and it was due to the drain holes at the bottom of the drivers side window. I removed the first two covers and installed some electrical tape over the holes and that took care of the problem. I now rely on the rear holes to provide for draining of the window channel.

I have the same issue. I think the problem is wind coming off the front of the coach and causing buffeting in the mirror. I have tried everything including changing out the entire mirror and I still get the obnoxious noise in certain wind/speed conditions. I don't know what to try next.

Very Interesting ! I have a new Tour on order so I hope others will reply.
Seems "MikSher", "Harry B", & "Texas TC" have a different idea about what is causing the noise.

Thanks, on my "to do" list is to check drivers window side weep holes for covers and try taping off, and I will try taping windows but do not expect this to solve problem. Has anyone contacted Winnebago technical services?

You might be surprised. If the driver's side drain hole covers are missing, this could be the source of your noise.

Have you ever verified by removing mirror and seeing if wind noise goes away?

I had exactly the same problem -- terrible wind noise on the driver's side window. There were no seep hole covers on the frame -- just the rectangular holes in the frame. My dealer gave me covers for each hole and they easily snapped in and the noise totally went away. Amazing!

Had similar problem with my Suncruiser, but on the passenger side. Replacing lost weep hole covers helped some. Ended up stuffing some foam rubber in the ends of the covers. No covers on drivers side at all, but no noise is present there. The mirror on the passenger side is offset on this coach and I believe that wind turbulence from its position causes the problem.

I have a similar noise problem with my Suncruiser. It is the mirror.

Now, I don't recommend anyone else do this - but I rotated the whole mirror assembly to the stowed position next to the side wall of the coach and then went for a test drive - noise was gone.

With the way the Suncruiser's mirrors are mounted, and my long arms, I could reach out the window and push the mirror assembly back into place, (and I could again see down the left side.)
I have since adjusted with the mirror head so that the mirror glass is flat across the head - no large gaps at the side of the glass.

That's my story, and I'm sticking with it!

Velvac was not synpathetic. They said their mirrors are quiet.

I had my windshield replaced before I headed south this year. The coach was noisier after the replacement. I placed duct tape on both side of the vertical trim on the driver’s side and it was much quieter. I then removed the tape and applied a small bead of mastic along the edge of the trim piece, noise gone.

Use tapes or duct seal to cover gaps, cracks, holes and ridges and see what difference it makes. When you find the guilty area, take steps to rectify.

Last fall I was parked next to a new TOUR that had duct tape across the gap between the mirror and A pillar. The owner was a long time Winnebago owner who actually made some of the machines that they use in their factory. He said that the tape was the only thing that stopped the noise and was looking to Winnebago for a better solution.

Thanks for all the great responses. I looked at my Itasca Ellipse today and observed that I have three 1.5 inch slots across the lower drivers side window frame. The forward slot has a cover. I also observed that the location of my driver side mirror could contribute to the tunneling of wind into those exposed slots given the correct wind conditions. My next step is to tape exposed slots and take on my next trip and test. Will let you know what happens in two weeks.

I had the wind issue also. Look under the left front end of the unit under the fiberglass. There is a steel tube structure there that supports the front end and fiberglass. The tube is about 1 X 2 inch. Look into the tube and make sure there is a filler inside. If it is hollow, fill that inner tube with something that won't allow the air to go up the tube. I used a foam product that expands. It worked great and took away my wind noise. There is just a small amount that comes off the mirror.
