Does somebody know why these plug are there ?

Wet Seatbelt Cause Discovered
 

After 3 trips to the dealer, My Nissan dealer could not figure this out. I discovered the issue and and took it back for a 4th time. The panel that runs above the window, from the windshield to the back window, has clips holding it in place. Those clips have a rubber seal where they meet the chassis. That rubber either deteriorates or distorts to allow water underneath. That is the cause of the wet set belts. I had my Nissan dealer replace both panels AND the clips, AND reinforce the rubber barrier, and so far, no wet set belt. Picture attached.

Those 2 plugs are what house the wiring going from the interior of the car to the back window for the window defroster, and were NOT the cause of my seat belts getting wet. (See Above Post)

What year is your car?

2016

I'm not discounting any of the theories in this thread, but I've had a wet seatbelt once (2016 car) and I'm pretty sure that I'd shut the door on a small part of the belt, which hadn't retracted properly. It rained quite hard, the belt got wet and the water wicked through a large area of the belt. Of course, in a lot of cases the wet belt will retract as soon as you open the door, so you won't know it's been trapped.

Ever since then I've been careful to make sure the seatbelt doesn't get trapped in the door and the problem hasn't recurred.

I am NOT saying there couldn't be another issue - just letting you know what happened to me.

Look like 2016 have a problem

In production since late '08 and the '16 now has this issue. WTF Nissan???

Just an FYI, what this thread is dealing with is every time it rains, the seat belts (inside the car in their normal position) get wet.

So i have try to put a lot of water and the leak seem to have stop. I gonna be sure only at the next big rain but for now it look like that it work.

I do apologise - I'll shut up then. Maybe in future I could pm my posts to you, in advance, for approval?
