Lots of wind noise, driver and pass windows

We own a 2014 Itasca Sunstar. Driver and passenger windows require modification or replacement according to local techs. Anyone else have similar problem?? This is our first class A, other two units were Class C's.

tks

On the Thor Owners thread, there are a number of discussions of different solutions for similar problems. The best seems to be add the cloth part of hook and loop to add press and help seal the windows.

Where exactly? Around the edges? At the middle where the front and back parts of the window overlap? The whole thing?

Our motorhome benefitted from tightening up the window frame screws inside and out. Maybe caulk around the outside frame? Also the weep holes whistled, so we bought little caps for the outside and made plugs out of open cell type foam rubber, from the hardware, for inside. This helped quite a bit.

X2 On the weep hole covers. When we brought our discovery home it whistled like crazy. A call to Fleetwood and a pack of weep hole covers later and it was all solved.

Pardon my ignorance but are "weep holes" drain holes? BTW -- The unit is still under 1 year warranty so we expect dealer to fix the problem. He is in discussion with Winnebago to determine how to proceed. I will certainly take your ideas under consideration should the problem resurface after warranty has lapsed.


Tks for quick response!!

Hi kayserc,
To test the weep hole theory (which I agree with) tape over the holes with the electrical tape. Then drive the coach. The weep holes are the drain holes at the bottom of the window casing. The weep holes are notorious for causing wind noise.

tks kayserc
One thing I found with our Sunrise is the majority of the wind noise, at least on the driver's side, is caused by the mirror. All that wind coming around the windshield and going between the mirror and body causes a lot of noise. I went crazy trying to find any air leaks around the driver's door and window and finally tried a temporary deflector that kept the wind from coming between the mirror and body. That eliminated 90% of the wind noise, now I just need to make a permanent deflector out of clear acrylic.

Ours start whistling at 45 mph and get louder with speed.
After researching, the following causes that were reported.

1. Weepers
2. Screen Window: Sliding it forward could also block the weepers.
3. Ford Grill

I agree that the weeper covers are the best possible solution to the problem. Going to try it.

Our new Vista 30T had a very loud whistle when we took delivery. After several weeks, I discovered that the cam lock had to be perfectly aligned with the slot in the fixed window. When not aligned, the cam forces the two windows apart and creates a gap that whistles.

Sunstar windows

Noises have been very annoying. Three issues. Weep holes. Cured by weep covers. Dealer can provide.
Latch alignment. Careful latching help a lot. But still weak. Will try velcro cloth pressure.
Loud cracking on bumpy roads. Dealer replaced windows. Still bad. Haven't found a solution yet 🔥
