What to do about wind noise?

[MTHook]

The new to us windsport 34e has a lot of whistle coming from the right side window area as best as I can tell. It starts about 30mph and just gets louder the faster you go.
Anyone know what to look for. I tried taping the hood down because it sticks out beyond the cap but that didn't help.
I can't see any place that looks loose or a gap that might cause the whistle.
You can't hear the radio over the noise

Anyone taken a side window out for repair?
TIA

If that's a sliding window there will be drain slots on the outside bottom channel.
There should be covers over the drain slots, thin long clamshell looking devices with the opening facing backwards.
If they are missing or loose you will get the wind noise that you are describing .
Nearly drove me crazy until I figured it out.

Thanks,
They are slides.
I looked and don't see anything like a drain, see picture.looking a drain

After I looked again I think I can see light at the lower bottom where the vertical rubber should meet the bottom rubber seal, the light is about the size of a pencil point which could be the problem. Both side look like the gap between the rubber is the same however I don't see the light on the Left side.
I think I'll get out the fix all duct tape and tape that window to see if that stops the whistle
Again thanks for the input, it may have cured the problem

That is a different style window than I have on my rig . I would still be willing to bet that the noise is from the drain .
If taping it stops the noise then contact Thor and see if there should be something in that hole that will let the water out but not let the air in.

My driver's side door does the same thing and all that I have found that works is open the latch.

A common problem with Windsports (reported here often) is windnoise coming from the design of the grill. The shape of the openings cause a whistle loudly under the right conditions, highway speeds. My 2018 29m did it and I too thought it was coming from the right side window. Based on comments here the dealer went back to Thor who confirmed the design flaw. They sent a new screen which is installed behind the grill with wire ties to break up the flow of air coming thru the grill. No noise since that fix. You can find multiple cases of the same issue on this site.
Don’t know the year of your RV but might be worth a call to Thor, they’ll likely send you the screen. Cut it to fit and wire tie it behind the grill- 30 minute job.

Just to see, pull your grill off and take a ride. It's only a few bolts to test like I did, it was the grill.

Ill pull the grill and road test it
Thanks for the heads up
