Water leak driver's side rear.

[Rusty Whitten]

Hello all, it's been a while since I posted as my last Ram died on me a few years ago. However, I've got another one now, and I'm dealing with a water issue. I've included a pic of the current leak. I had a leak on the floor and replaced both of the exhaust vents, and after a heavy rain here, I didn't find any new water on the floor. I also didn't find any new water on the ceiling, but this is directly under the shark fin antenna.

I've ordered a new third brake light since I've seen that be the culprit in many cases, but I'm debating whether I need to pull the antenna and try using a silicone sealant to seal it up. But the lack of any new water in the ceiling has me wondering. Opinions? Thanks in advance everyone.

It is most likely the shark fin antenna. My truck has the same exact issue and is leaking at the same spot. My shark fin antenna has a gap where water can easily leak through. All I need to do is get some kind of silicone to fix the gap.

I just went and checked and I was able to move the antenna. Looks like a tightening up and silicon job is in my near future.

Sounds like the shark fin may be your problem was your truck facing any certain direction when you saw water on headliner and floor, your rear floor may be coming from your rear slider window (cracked Frame), clogged slider drains or cabin vents missing rubber flaps, there is a new upgraded cabin vent available, you said you're going to replace the 3rd brake light Assy (CHMBL)

I replaced the vents this weekend and noticed the staining on the roof while doing so. I do have the 3rd brake light coming, and I'll check the slider window.

3rd brake light coming

I've not heard of the light being an issue. Seems to me it has always been the light seal that is the problem. It's a low quality seal. https://www.ramforum.com/threads/leaky-brake-light-fixed.91885/

Yes, I was going to replace the seal by itself, but I don’t really like the light so I was looking for something different for it as well

Update to everyone who responded to this thread. I believe the leak problem has been solved. I replaced both vents and replaced the gasket on the the third brake light just to be sure. We've had several storms, and I've found no new leaks or wet spots in my truck. I appreciate you taking the time to respond!

Thanks for the update, glad you got it fixed.
I did my vents recently, it rained every day last week, it’s a great feeling not wondering if water is getting in the cab.
