Rear window leak

[theblet]

So I tried a couple fixes for my rear window leak and this one seems to be the fix. Will have to see how it holds up after a couple years though.

yup. That or permatex

After a good down pour I still have a leak. I did end the urethane before the corners so I will add an additional bead to round the corners and see how that holds up.

Another update.
the additional urethane did not solve any issues for me. Luckily I have a family member in the auto glass business so he is familiar with the issue and recommended a full replacement from MOPAR. Here are a few pictures he sent me this morning.

Add me to the cracked/leaking rear window club. So far ive tried 2 layers of flowable silicone over the whole seam where the window meets the cab, also sealing the cracks in the frame and anywhere else I can see where water could enter.

Ive slowed it down, but not stopped it. Next course of action is to totally fill the void between the top of the rear glass and the cab with UV Resistant urethane. If the entire width of the glass is filled ( down the corners some too ) , even if there was 20 cracks it shouldn't leak as water cant get in

my truck is over the 3 year warranty mark so im on my own.

I just filled in that gap with urethane body seam sealer on mine, so far no leaks from 2 days of real heavy rain. But let's see if it lasts...

Check with your auto insurance. My comprehensive deductible is $50. A lot better than what the dealers charge

This is an interesting one. Lucky for me, as mentioned in this thread, my dealer did me a solid and pushed to have it covered under a previous issue I brought up to them when it was covered by the factory warranty. For anyone dealing with this and not being able to have covered by the warranty, this may be an option.

Pretty much what I just did. I use USAA for insurance so there is no local branch and they didn’t require pictures or evidence of the window being replaced. I just told them I woke up one morning to it being “broke”, nothing more was said besides that. To them it seemed like a total window loss and that’s all they needed to know. Now my new window has been in for 48 hours and no rain. Oh, and my deductible is $100 but the shop did some magic and got it to $50.

Since one of my family members is in the auto glass business he has the inside track to some Of the OEMs and auto glass technician forums. He told me that the reason the plastic frames crack is due to people holding the slider button down too long once the glass has reached its travel limit. Whether that is true or not remains to be proven.

I barely used my rear sliding window leading up to the crack so I personally doubt that. It seems plausible though.

I was told it was a combo of poor construction along with the adhesive used. The factory adhesive they used was not flexible enough and after enough bumps, turns, twist the cab would flex the window frame and crack it. The service tech who got mine replaced subbed it out to an autoglass shop that (supposedly) uses a better suited adhesive that flexes more.

If that's the case then it's still a case of terrible design. But I doubt that's true given what people with this issue have said over the years about not even opening the slider. In our case, I never opened the slider. But the wife uses it every time she drives it. Can't say whether she holds the button too long and I'm not asking her LOL.

Just tell her it's her fault. You don't need them anymore.

So it finally happend to me, took my car to the car wash today and noticed a soap line in the corner of my passenger window. I tried pouring some water in the spot on the outside but there was nothing coming through, I remember someone mentioning somewhere that if your frame isn't cracked and you get a leak in the corner it's the 3rd brake lights, I can't seem to fine that post anymore lol, would I just use new weather strip to seal around the 3rd break lights?

There’s an updated part from Ram that has a new brake light with the new style gasket already installed. I just did mine and it was $45 shipped. I don’t have the part number on hand but I’m sure a quick search will turn up something.

The screws also were changed/updated.

Can you see if you can get me the part #? I tried looking it up and couldn't find anything

FYI

3rd brake light leak VS. cracked frame

So why doesn't one just use a tube of black silicone and fill the gap between the rear window and body then smooth it out with your finger. Very good question. After they installed the new rear window in mine it still leaked. However, there was visible evidence that they missed applying...

Hmmm would this piece work on the 3rd brake lights with the digital rear view camera ?

I'm not aware of leaks with the digital rear view camera, stress "I'm not aware", perhaps some other forum members can give their experiences with the digital version.

Do not waste your time with the weather strip like I did.
Just order the new style break light, like 36 bucks or so.
