I've been secretly stopping by the house and putting water in there. :)

1 of 2 reasons.

1. tail light gaskets
2. gaskets on side flip out windows.

1 is usually more the culprit

Yeah, its usually the tail lights. You can buy the thin craft foam at Hobby Lobby/ Michaels and make new ones. Ive done it with my car and Jermaines old hatch. Cheap, easy, and works.

Just trace the old ones and cut them out.

My driveway is a little steep going up. 

The other day it rained pretty bad and when I went out to drive the car, as soon and I hit the brakes at the first traffic light I came to, a bunch of water came into my floorboar d from behind the drivers seat.

I recently had the windshiel d re-sealed, so it's not coming in there.

It only seems to accumulat e in the back seat floorboar d on the drivers side.







Anybody else got this problem?

Where could it possibly be coming from?

How to fix?

Yeah I have the same issue in my white hatch.

Stripped out the interior this weekend.

I have water in two places.

1. both sides going into the spare tire well.
2. passenger side foot well.

1.

Once I stripped the interior and started spraying water out I figured out where the water was coming from.  I could see the droplets of water coming down the inner upper panel near the flip out windows.  Looked closer at the gaskets all good.

I removed the plastic at the flip out windows and did it again.

Figured it out from there.  Coming down from top of hatch area.  If you open your hatch you will see your hatch hinges.

got to the right of the passenger side hinge.  If you see the seam where the two pieces of metal join.  Look for gaps.  Found both on mine.

Filled with seam sealer.

2.

looked more at the front windshiel d area and found the issue, water dropping thru ac part.

looked closer, took of cowl panel and wipers.  pulled little panel over the top of wiper motor.  Cleaned all crap off there and put seam sealer on that.

That is the two issues I have found.

Rbw,

I don't think 1 or 2 is my issue - simply due to the location of the water accumulat ion.


Let's just go ahead and make this the official water leaking into interior EF thread.

I originall y had water dripping in from my visors area in the passenger side front.

I removed the sunroof and checked the drain tubes.

I removes the front cowl and the piece that goes to the AC cover thingy.
Removed the foam from it and sealed it with new sealant.

Didn't help.

Then I had the windshiel d resealed.

That fixed it.

Then I noticed the water in spare tire well.

Thanks to bdj and Richard for the help with that one.

Now is this wierd water in rear drivers side floorboar d issue.

I guess I'll be spending some hours with a hose to troublesh oot.  :/

Check all seams around open areas.  That is where I found mine.

i had an 88 hatch that leaked from the butt welds over head, where the roof and side meet. it was under the black plastic strip. The seam sealer had cracks down all the way to the hatch hinge. it would come down under the corner between the tails and pop out window. then make a lake in the spare tire well. and the windshiel d omg did that thing leak!! took it to the local safety lite shop for a new windshiel d and when Steve pushed from the inside to see how loose the seal was the glass came right out.
but after that she was high & dry.
and btw I have an 08 GD3 Fit and it started the same weird leaking and it was the same butt welds / seam sealer cracks. ya think after 30 years Honda would come up with a better idea. repaired with JB Weld and no more water!

I got a cel code 16 while limping the car home - it started randomly sputterin g and running like shit while the tach jumped around all crazy and the wideband gauge also gave some crazy erratic readings.
Also it gave me a very dim CEL flickerin g.

I removed the hondata s300 ecu and conversio n harness and took them in the house to check them out and inspect for water damage. I found evidence of moisture on a couple of the pins in the connector for the conversio n harness and dried them out.




​​
​​​​​​​I hope nothing is fried!

I bailed about one gallon of water from the rear floorboar d on the drivers side and another half gallon of water from the rear floorboar d on the passenger side.

​​​​​​​

I checked the rear window seals and found that the screws holding the window hinge to the b-pillar were not tight - the seating to the chassis is a bit stripped. This is the suspect area IMO.

I decided to drill three small holes in the chassis to prevent future water pooling issues:

One behind each seat in the rear floorboar d, and one in the spare tire well.

I peeled off the roof gutter trim on drivers side and inspected the area - no evidence of a crack or leak there.

I'm going to check the inside of the roof panel today and report back.

* thanks Richard for the phone support - I should keep you on retainer!

Troublesh ooting CEL from water...

I'm using an obd2b harness and water really only affected:
- pins 14/15/16/17/18/19/25/26/27/28/29 in plug A
- pins 9/10/11/20 in plug B

Of concern is pins 15, 18, and 19 in plug A - for fuel pump relay,  MIL, and engine speed pulse.
There are several of concern - looks like ignition power, signal, and ground and injector #2 in plug B.

I found the pinouts here: http://technet.ff-squad.com/wiring.obd2b.htm

I checked inside the hondata s300 case and all looks ok.

So hopefully now that the ecu and wiring is dry, there won't be any permanent damage.

*fingers crossed*
