Interior Water / Interior Condensation Issue

[jimmyjam24]

Hi all. Any suggestions please
Just noticed after going through the car wash at night when temperatures drops the interior is building condensation...a lot!
I already had the 3 rd break light replace as was leaking earlier. I know I have leak somewhere but where to begin. So very disappointing.. Uploading a picture

I had the same problem and brought the truck into the dealer this past Wed. thinking that the third light was the problem. The did a leak test and reported that the third light was leaking and both corners of the glass. No cracks in frame but I found soaked carpets under my rear floor mats afterwards. I've never had condensation like this in any vehicle before so it didn't really register that I had leaking until I got the repair estimate for new rear glass. Checking online now shows this is a well documented problem with the RAM. as well as other trucks.

I'm going to do the Permatex fix and see if that solves the problem. You can find that mentioned elsewhere in these pages.

But after seeing all the complaints re: the cab (exhauster) vents are also a problem with the 2021 and plan to change them out for new ones once I pull the rear sheets to dry out and "demold" my carpet.

Does anyone know if the cab vents were "upgraded" with the 2021 RAM?

Rear window frame most likely.

leaking and both corners of the glass. No cracks in frame

The corner cracks are not visible from inside.

I did Permatex all the way across and down the sides.
RAM extended the rear window-frame warranty, you might fall under that, worth checking.

Thanks, the dealer failed to mention an extended warranty. Maybe because the frame shows no cracks. Waiting to hear back from RAM Customer Care.

Just saw your previous post. "The corner cracks are not visible from inside." Thanks
