I have a 18 Chevy Tahoe custom with less than 2k ‘miles on it. I have noticed that I get a small amount of water coming back from the rear view mirror mount when I’m driving. I attached a picture (it’s hard to see but if you look closely inside the circled area you can see the water). Has anybody expierence this before?

I haven’t done anything to that area besides add an eyebrow tint.

Thanks!

My guess is that your shark fin antenna is leaking. Does your headliner feel "heavy" or wet? Been getting a lot of rain where you're at?

Could just be a bad install from the factory. Take water hose and put it just on the top of windshield and see if it runs in if not move to shark fin then u can determine location. Probably a faulty install from factory. Depends on how bad leak is it can probably be patch from inside at dealer or glass shop

I had some sort of oil run from the exact spot. Wasn't water but clear fluid/oily substance. Wiped it up and haven't seen it since. 2017 Yukon SLT.

We hadn’t had much rain lately which is why I thought it was really weird. I didn’t think about the fin possibly being the issue. I’ll have to check it out.

MW, your right. It looks more oily than actually water. I was going to leave it there until I can get into a shop but maybe I’ll just wipe it and see it happens again. Thanks!

I would bet this is the issue, happened on my 2016, a common issue apparently.

Dealer says its some kind of "gel pack" leaking from the rearview mirror module. Apparently I need to replace the rearview mirror. Definitely not water. It's an oily substance.
