Ceiling Drip From Vent

[masterdrago]

Been noticing fogged inside glass recently and found wet at back under sliding window to bed. tightened up the screws holding the bed/stop light combo. Leak stopped. After several hard rain days, noticed the front drivers side window fogged again. Found drivers seat wet and drip from the little (unknown for what) vent above drivers seat. I checked the clearance lights (they had been replaced under a recall) and the XM antenna seal and all look okay. Any ideas?

Most likely the clearance lights. Could be a crack from an over tightened screw.

I'll take a closer look when the rain quits but from the casual inspection, they look fine. They were all replaced 10 months ago by the dealer. If they cracked one, it should be rather large to allow as much water as I'm seeing. Maybe one of the lights is not tight at all. On the back of the XM antenna seal, there is a small square cut (as in factory seal opening), but it is also very small.

I had the pinch wield in the roof leak. Drove me nuts as it would run from the leak inside the roof and come out elsewhere. Also I found the sliding rear window wasn’t glued in right.

@masterdrago
That is not a vent. It’s one of the two microphones utilized for voice commands and Bluetooth phone communication.

I hate to say it, but sounds like you may need to drop the headliner. Leaks can cause mildew, rot, and rust. I think you might get by opening the sides and rear to get a peak. Might be worth getting one of those cameras that are used to get behind things. drop the dome light, and go through the opening to see what's going on.

Just suggestions. Please keep us informed on your progress.

Cheers, Ron

Tape off the lights and antenna one at a time with masking tape and see if the leak stops. Then diagnose from there.

The headliners will not usually absorb water like they used to. Very little chance to do any damage except for possible staining. If it has been really wet it wouldn't hurt to drop the sides down a bit to help dry it out and to see where the water is entering. Note that where the water appears is not where it is entering from. It can travel inside double body panels or along the headliner to where it finally exits.
To properly diagnose you isolate the entry point, then flow (not spray) water over one area at a time to verify.

I almost think it depends on how the truck is parked (angle). Pretty sure not the clearance lights. All are tight and do not appear compromised in any way. Microphone? Always wondered about that small fixture above my head. Guess the Chi-Coms are listening. Hell, they can probably drive the truck via my cell phone! What is so irritating is I have a Towncar with a leak getting to the passenger side rear floor. These kinds of leaks can drive one nuts. When ever it stops raining, I'll get a better look.

I would pull the headliner and each of the clearance lights. If one of them is leaking youll be able to tell by dirt, dust residue on the inside of the roof. Then you could apply clear silicone sealant to the bottom of the lights and the screws that hold them in place and reattach. You should also do the same with the sat antenna and the radio antenna's to prevent them leaking as well. I would hit the 3rd brake light too. I did all mine even after having the dealer fix it once before and it still leaked so I took care of the issues myself the next time.
