2000 Honda Civic EX - Wet Floorboards (FIXED)

There are several reasons why you may have wet floors in your car. With the 1996-2000 Civics, particularly the EX and Si, the sunroof drains can, and usually do eventually cause issues.

A lot of people will tell you to unclog them or whatever, but while I was trying to do just that, I found a separate issue. When I tried blasting compressed air through the drain, I realized that the air was going inside the car instead of outside in the wheel well where it was supposed to.

So this is what I found and how I fixed it. You don't have to take as many panels off as I did, but since issues like this are difficult to figure out, I just tried to make everything as accessible as possible. To get to these hoses, you should only have to remove the lower dash panel (3 screws, also disconnect the wiring harness from your mirror and sunroof controls.) and the panel that fits in the lower corner that your hood latch is surrounded by (snaps into place and is held by 2 plastic anchors).

After taking those off, remove the two bolts holding your hood latch cable in place, and tuck it out of the way, then remove the one bottom bolt to loosen the metal bracket with the black box connected to it. (I don't believe you have to actually disconnect that black box from the bracket like I did.) The hoses should be fairly high up behind that bracket, gently bend it out of the way to access them.

I simply put a hose clamp around the black hose, then reconnected the hoses and tightened the clamp down to hold them in place.

So far so good. Hoping this holds up for the long run.
