I get water accumulating under my passenger side floor mat too, but I haven't seen any water come out from jacking up the rear or anything. Would it be coming from that A/C line pictured above?

The sunroof drain could be clogged or you got a damaged weather seal? Corroded windshield frame?

The reason why water won't come out when lifted could be your truck still has the rubber plug on the metal floor. Just lift the carpet and remove the rubber plug and drain water. Let it dry and put back the rubber plug.

That is the sunroof drain. Just cleared mine a few weeks ago, and got the same fountain. Probably just jacking it up moved/stirred the water so it all drained in a stream like that. My front floors were also getting damp when it rains, and clearing these drains seemed to help. It almost seemed like the door seal (around the front of the door near the hinges) was leaking too, but I haven't confirmed that yet.

Well, I'm about to shoot my self! I look at the driver side rocker panel and THERE'S SO MUCH WATER JUST SITTING!!!!

I stuck a little cardboard piece in there.


About 2" of water!!!


I don't know if this has anything to do with it? But A while back I noticed these holes under the truck on the side of the rocker panels had factory type material over it. Basically covering the whole with tar type sticker. It was pealing of so I pealed it of and put my own on there. To seal it.


But I doubt this has anything to do with it. As the passenger side is the same way but inside the rocker panel its bone dry on the passenger side.



Driver side, looks like water is trying to drip out but its having a hard time!


I looked at my front window seal and around the window and theres no rust and the seal looks VERY VERY tight!


Im guessing this is my AC drain? Looks pretty clean!


So, I still need to figure out why my driver and passenger side floors were wet, and WHY I HAVE A POOL INSIDE MY DRIVER SIDE ROCKER PANEL !!!!!

Haven't you posted numerous times that you have had water in your truck and your mats were wet? Seems like you never tracked down the original problem either.

get a roll of weed eater line, and feed it up the drains from the bottom.
double check that the line comes out the drain. perhaps the hose has popped off a fitting. or is just very clogged, and water is going where its not supposed to.


earlier this year, I opened the rear hatch, after not having it open for several months, several very wet months. as soon as it was all the way up, water started pouring out of 2 very small holes just at the top. WTF.

looking at the bottom of the rear door, there were a couple rubber plugs. I just removed them, so the water can drain as it gets inside. im not sure why they were in place to begin with. I haven't noticed any more water in there since.

There was a thread a long time ago. But I narrowed that down to the type of wire loom I used on a wire that goes through the grommet. I fixed it with a lot of RTV. And that was only driver side.

Now it's passenger side. And driver side rocker panel FILLED WITH WATER. something is clogged up. And I'm not sure where to look

at the end of the ac drip line, there is supposed to be an aluminum tube that is bent at a 90-degree angle

when the rain stops, why not remove the carpet and then pour a cup of water in each of the two moonroof front drains to see if the water goes straight to the floor drain holes in the rocker panel or it just floods. if it floods, then most probably the holes in the floor where the moonroof drains could be clogged with dirt.

I'm going to try to express my self in the best way I can lol.

So when I bed line my rocker panels. I bed lined the bottom part. Let's call this the pinch area. And maybe I clogged up the little drain areas ? But I did this like a year ago. So I don't think this is the issue.

Another thing, I recently sprayed Eastwood heavy duty grease type inside the rocker panels. (Maybe this could have clogged up the little drain holes ?)

Can someone verify that the sun roof drains into the rocker panels and then water finds its way to the drain holes ? By looking at the rocker panels. There are area that are shaped like drain areas.

I stuck a little rubber tube inside the sun roof drain holes. The front ones. I blew air and poured water down. It seems as if water from the sun roof drains "into the rocker panels and then drips outside". Does this sound normal ?

Found this little thread

https://www.yotatech.com/f2/front-su...rocker-297116/

To my understanding. The sun roof drains are short and water runs into the rocker panels then out the little pinch weld drain areas. "The front does drain out gaps in the pinch welds on the rocker." Quote

I think it is this "Another thing, I recently sprayed Eastwood heavy duty grease type inside the rocker panels. (Maybe this could have clogged up the little drain holes ?)"

Clean all that.

Clean inside rocker panels ? May god be on my side. I'll be posting pics soon of how I extended the sunroof drains "straight to outside". Rather then into the rocker panels. Explains why rocker panels upfront rot out.

What I did is I stuck a thin rod and loosened up the drains and water drained out.

The front drains for the sunroof exit in the rocker panels, this is why there is water in there.*You need to pull that tape off the bottom of the rockers so they can drain properly. then use some kind of wire and gently clean the drains out from the sun roof. I honestly think all your water issues will be solved if you can get your sunroof to drain properly. If the water cannot go out where it is supposed to it will go somewhere else where it is not supposed to go

Yeah I agree. I hate to ask. But could look under your truck to see if those holes are plugged on your 4runner ?

I've actually yesterday extended the driver side drain with a coupling and extra hose and ran it outside the rocker panel to the outside !! I'm hoping to clean this mod up and then there will be 0 water draining into the rocker panel.

Ok, so ive been very busy. And honestly I believe that I have came up with a easy solution to avoid the sun roof from draining into your rocker panels. If you ask me, this is stupid. Im sure 99% this is why the rocker panels rot out! Toyota extended their drains in the back to the outside. But the fronts... come on? really into the rocker panels?

I went to Home Depot and got a coupling 3/8 and 3/8 hose.


Remove the driver side plastic kick panel, and you'll see a yellow sponge. Take that out and you'll see a drain tube. Pull it out. Its not easy takes little effor but don't be afraid.


If you look down there, at a certain angle. You will see a small opening. Carefully snake your new tube into that hole.


Outside of the truck. Behind the plastic fender wheel cover there is a small gray/silver plug. Its plastic, so it does not water tight seal it. Remove it! Most likely you will damage it lol.

So, in this picture you can see the new clear tube. Through that hole.


You use pliers and grab the clear new tube and pull it threw that hole. Then slide a new rubber grommet over it and tightly into the rocker panel hole. Yes, i know the 90 degree bend on that tube is not pretty. But believe me. The tube is strong and thick. There is a good gab for the water to drain out.



I also put RTV around the tube where it comes out of the grommet to seal it little better. The grommets inner hole was slightly larger then the new tube.





I tested the sun roof drain.


Good tip. Once you pull the new tube out. Then connect it to the original drain tube with your coupling. And it wouldn't hurt to wrap them both in electrical tape after they are connected. Makes it so when you pull the white tube out side you, the coupling won't slide out of the original drain tube. Self exploratory.

Same concept on the passenger side



Look closely...


You see the hole! thats the hole you need to put the rube through in order to see it outside the other hole.

And this is the passenger side


I tested it about 30 times and every time the water drained out nicley and DIRECTLY OUTSIDE! Once the plastic fender cover is back on. You cannot see the drain tube

How is this holding up? Has anyone else tried this?

I just patched a couple holes in my rockers and am hoping to extend their lives as long as possible - and my pinch welds are somewhat corroded
