Rear window leak 2019 Minnie Winnie 22M

[CantTakeit]

Hello all. I have a Minnie Winnie 22m. I’ve recently seen a water leak in the rear window (escape window) underneath the window frame during a fairly heavy rain. After the rain, I tried to replicate conditions with a hose and water did enter through the bottom weep holes, but did not enter the coach from underneath the window frame. Rather, water collected inside the frame on the inside of the coach. Heavily sprayed hose on remainder of window and no leaks originated in any other part of the window. Maybe this was just a result of heavy rain, but wondering if anyone else has experienced this problem and what your remedy was. Many thanks.

Hi CantTakeit,

1. When you open the window, do you see anything that looks like an accumulation of road dirt inside the channel?
2. Are the external weep holes totally clear?
3. How is the rubber seal?

Thanks, Eagle5

Check above the window, clearance lights and such.

Hi Eagle5!
It’s been crazy these past few years, glad you’re good.

Working on it, will let you know.
Thanks again!

Hi CantTakeit,
OK, so from your personal message to me, it appears that your clearance light(s) are the source of the leak. From this site:
https://www.winnebago.com/owners/own...s-and-diagrams
you will see this link:

and for our 2019 22Ms we have:

For the Clearance Lights, the specified product is:
Sealant C = 185987-03-CHT
I always go to my local dealer and get the exact Sealant number that Winnebago specifies, so I know the bonding will be good. Be sure to clean the area with rubbing alcohol beforehand.
Good luck and let me know how it goes.
Thanks, Eagle5
