Wet under weather tech floor mat

Update!

Getting really annoyed. After removing my carpet, power washing it. Installing new carpet padding because the OEM was shot and wet. And after running , few wires through original grommet I've been noticing that under the driver, left pillar it feels wet under the carpet when it rains. I put a full tube of silicone from inside and engine bay side around the wires that run through the grommet. Sprayed water on it to see if the water is still penetrating. And I didn't see anything unless I'm missing it. And it's very annoying knowing I keep finding moisture / water. The black stuff is por15.

You can see little bit of moisture. Some soaked into the carpet padding. Actually few days before this, I cleaned up little more water then this. There was some in the V channel. It's been raining in NJ for last week and half.



I noticed it wet around both plastic plugs. But from under it looks like a tight seal. And the same from inside.



Looks dry, no water trail. Next to the pedals. I'm sure I'd see some? No?



This is undercarriage right under the driver Rocker panels. Hard to see but each 4Runner has those holes in the rocker panels. Usually covered with a tar type 1"x1" tape. Mine came of. Due to years, power wash , off roading. So I think maybe water splashes into the hole, and up through the little openings inside the car ?







Anyone having or had this issue ? Could it be the wires going through the grommet ? 2 4g wires and 5 12g wires. But I put a lot of RTV silicone.

Another conclusion I have, that because I have the wire loom over the wire. Not the plastic kind. You can see in few pics the style of wire loom. That the water seeps through the loom , down into inside ?
 
Could you have someone blast the truck with water while you sit inside and see where the water is coming in?
I might help to dry the existing moisture in there now. And if you can, line the floor board with newspaper, or some kind of light weight paper. The paper makes it easy to see drips when they start to run.
 
Your signature indicates you did a 5 speed swap. In 1st gens it's common for leaks around the clutch pedal. I'm sure you've checked but consider it if you haven't. Usually brake fluid and not water.
 
Good tip on sitting inside. As you seen in the video, it was running down the wire and dripping inside. So I fixed that. Well I though I did, might be the same issue. But I used a lot of RTV and pushed it good with my fingers.

Yes I did a 5 speed. Didn't actual consider the clutch cylinder. It has a OEM gasket. But it's possible. What do you mean by brake fluid ? The clutch cylinder seems full.


I'm just surprised that I don't see a water trail. I might put news paper like stated above. And just start hosing the car

I didnt read through the thread but you have checked around the windshield for leaks? Buddy had your same issue and ended up being a badly sealed front windshield.
 
Ever figure it out? I think I have the same problem

Check post 18.

It's water dripping down the wires going inside. A lot of silicone has fixed the issue. I check it once in a while. Mostly after rain, or car wash. But it has been dry.

Oh ok, I thought it was still leaking, from post 21.

I think I put more RTV and it stopped. My issue is I have wire loom over the 4g wire. And even with silicone. The water would get under the wire loom and travel down the wire.

Do you yourself have a lot of wires through the original gromet ?

Just one skinny amp power wire. I'm gonna silicone it up and hopefully it solves the problem.
 
The skinny red wire in the pic. I think it is only an 8guage

sunroof drain tubes check

This might help somebody, if not the OP.
I had this exact issue and it WAS the sunroof drains!


Is your headliner wet AT ALL?

Pop off the "oh shoot" handles, remove the plastic trim and pull back the headliner. From there you can visually see the tubing. Make sure it's actually connected.

You can pour water directly into the sunroof drain holes and watch the water leak down onto the floor boards!...

Heres a few pics.

spray water on the windshield on the driver side with the hood open. Watch if the water drips down and straight onto the wires going through the grommet. Then look inside and see if you notice any water dripping.

Also check ur sunroof. But if your headliner is dry then thats not the issue. My money is on the grommet. Again, do what i said above... you can see my video

I've got the same issue on the drivers side, it's definitely water but not sure where it's coming from... Soon as this was mentioned it made perfect sense because:
