My DC is leaking - what is the root cause?

Holy Grand Canyon Batman, now THAT'S a gap! Dude, wtf?

 

With the brighter lights that stuff will probably shine around whatever is blocking it.

I pulled the headliner on mine, not terrible, but I did drop some white body clips down the voids.

This is true, if you don't care about the existing light and are ok with breaking it. I wanted to keep mine in tact so I pulled my headliner down a bit to get to it.

 

@Rujack If you wan't to replace it and/or change it out for a MESO one, and are in the MA area, I can totally do that for you.

 

His is already fucked. Plus u still install the meso externally

 

Well, if its already fucked, ignore the headliner, lol.
Also still very true. Unless you have the CAM models, then you need to somehow run that wire down and through somewhere, which I had to do.

 

Shit no my wasn't even close to that! That one you might want to drop the headliner for lol. Not sure where you're located otherwise id offer to help.

 

That is INSANE! I honestly couldn't even see a gap in mine to speak of but there were a few areas that seemed more like pin holes in the surround. I just ran a very thin bead of silicone around it and so far so good - had a LOT of heavy rain today and no moisture/drops inside the cab and the headliner is dry. I'm going to keep an eye on it and once we have some dry weather for a few days straight I'll likely put a little more silicone around it for good measure.

 

This ^

 

If longer than 4 hours you're supposed to call the doctor.

 

That's bush league
