Driver Wind leak Help

k9jkfham · 04-11-2021, 07:44 AM

My 2014 Vista 35F motorhome has recently developed. Anything over 35 mph I get a high pitch squel. I have not been able to locate the source. Someone did suggest I maybe missing "Weep Hole Cover" I am not sure what they look like and not sure if this coach had them. I have checked all the windows, especially the Driver and Passenger windows and do not see anything that I think is missing.

Has anyone else experienced this and if yes, How did you repair the problem?

Weep holes are slots at the bottom of window slide rails. They are rectangular and about a 1/2 in length. When rain drains down the window, into the slide rail, the weep hole drains it to the outside. ALL sliding windows have them. A weep hole cover is like a miniture vent cover. It keeps the slot/weep hole from whistling in the wind. If you can see the weep hole, the cover is missing. It is a VERY COMMON problem. Most people use RTV to lock new covers in place. Why the factory doesn't do it is a mystery to me.

Not what RTV means. Are the holes on inside or outside?

Holes are on the outside, so that water drains to outside. RTV stands for Room Temperature Vulcanize. It is a silicon based rubbery coumpound that comes in a squeeze tube. It is gooey out of the tune but solidifies to a rubbery sealant. Good for sealing cracks and holding things in place. Comes in clear, black and white. EDIT DO NOT plug the holes. If you do, water will drain on inside of window.

I see several are missing. Does every window have them? I see each window has 4 slots with nothing in them

While all the windows have them only the front two windows have the covers - and yes, 4 on each side. When you order they have different part numbers for left and right side.

So I only need to replace the ones missing on front 2 windows.

They are also on ebay -

If people riding in the back complain of wind noise, they can be installed on most windows. Usually only the front windows come with covers from the factory.

You can order direct from Lichtsinn RV, they have a great part dept. I can’t find my receipt from last year, but I think they were a couple dollars a piece through them.

Check the vent for the fan over the stove ! Could be a likely source .

I just received some I ordered from litchinn rv. 1.70 a piece. I have a 2017 Winn Vista 29ve. Called parts and they shipped very quick. He will ask for your serial number for proper sizing.

We had a huge amount of wind noise at the passenger window, but not the driver window.
All the weep holes had covers, but weren't sealed to the frame. Since I didn't have any wind noise on the drivers side, I didn't think sealing them would help. Boy was I wrong. Sealed the passenger covers to the frame and virtually all of the wind noise stopped. Now I can hear the small amount of wind noise on my side. Will caulk those also now.
Wonder if the difference between the sides is the angle that the mirrors are pointed. Might produce different wind patterns on each side.

Thanks to those that posted about caulking these!

I ordered 8 weep covers from Lichtsinn RV to replace all missing Weep Hole covers in the front two windows. Noise gone and much quieter. I put a dab of clear silicone on each window with tooth pick to keep them in place since they just snap on. Problem Solved.

Thanks for all the suggestions.

The Winnebago part number for my coach is 186175-01-01A
