Rear Windows with plastic vents

[Skullbag]

This thread still alive? I had the drivers rear vented window seal done at a van specific shop here in Seattle. I had them do it cause it rains here all the time and it was leaking and migrating down behind the table panel (weekender) and there was already some rust. I didn’t have time to try to deal with it myself.... they did the seal and it’s still leaking. It pools on the top of the bottom seal. I can’t locate where from. Not condensation cause it’s only this window. The shop could never replicate the leak prior to replacement. They did not do anything with the seal btw the vent and the glass. I added some silicone to the top and bottom inside and outside of where vent meets glass the other day and still had some leaking... so last night I laid a trail of talcum powder along the bottom seal to see if I could find the spot. It didn’t leak!!! And it rained all night!!! I then sat there with the hose on the window for a while and no leak... wtf... anyone have issues with the seal btw vent and glass? I planned to bring it back to the shop today, but no leak and didn’t want waste time.. my last thought is to do that bedding glaze and new sealant along vent and glass.. if it leaks again..

Well, leaked again. While out driving. Wonder if the wind is pushing more water under the seal, or there’s body flex that allows more in? No shortage on hills etc in Seattle. I have someone coming to do my windshield on my Jetta and may have him look at it or pop it out and place some glaze in the seal.

Is it possible to get the plastic bit of trim that goes between the vent and glass. Has anyone had any success finding one of these?

Eureka Reading this thread made me realize where the mosquitos might be sneaking in! Is it possible to replace the foam without pulling the glass?

Here is a link to the procedure I used to replace the foam in the rear vent windows.

Nobody seems to be addressing the outside portion of this vent box. I can tell that mine used to have some kind of foam tucked in too, but I have not seen any new enough to still have it to look at. Ideas?

Kamz,

Ya, followed all the links I could find this time around as well, and it seems that the full length slots on the inside are the ones being addressed by the threads.

What I am seeing, way inside the box, are several crimp like sections where there is a tiny bit of spongy stuff, I believe its the leftover bit of stuff that had originally been in the outside of the vent box.

Again, I have never seen a new-ish or well kept vent box, so I may be wrong. It just seems as if there could be a bit of stuff tucked in those pinch spots on the side with only 1/2 the length having the vent holes. The rubber flopper would then be up and behind this (?imaginary?) filter.

Anyway, I have not found any threads dealing with how to keep bugs out of the outside portion. Thought I would toss it into the mix.

Later, I will get some pic's and post, if I can get my camera to focus on the pinch locations I am mentioning. (I installed one side so far, but still have the DS glass/vent to install on Flossie)

It looks just the same as the inside crumbs.. here are a few pics

Clearly, there are a few considerations to keep in mind. You can see that the rubber flap strikes the outside casing. It needs unrestricted articulation. So, the filter needs to not be inserted under the retainer the full length, as you can see it would cause restrictions if so. Also, to create a full coverage there will need to be a few layers, I'll probably find some adhesive and make a pocket in a few layers to go around the retainer on both sides to grab it.

I thought I would add to this too. Foam was crumbled or non existent. I found a shop Vac cover in my garage... Why not? Looks the same, right length when cut open.
I just fished it through with some picture wire and used a popsicle stick to help push. I found starting in the middle was easiest and work to the ends. 1 grateful dead song later, they were both done!

Ok, so I got my windows back from tinting and I am about to put new seals on the rear vented windows. I found the vents had a dab of silicone on the top and bottom and as I recall, there was about an inch on the glass too at the seams. I am wondering if the silicone was for sealing or to hold the vent rubber seals in place?

Can anyone provide insight? a dab of new silicone, or go ala-natural sans silicone?
