I registered on this forum today just to post this fix, as I did not find one that was the same as mine.
2003 TL-S, floor area was soaked after raining or car wash. I pulled floor sill plastics and removed the main relay by the parking brake area, sprayed water all under the hood and cowl, and checked to see if any drips coming down by the dead pedal. Nothing. I opened the sunroof and poured water down the drivers front drain in the sunroof. I could see water coming from the foot-well. The sunroof drain hose was unhooked from the 90 degree rubber tube-grommet. You have to pull the rubber tube-grommet out and put it on the tube, then reinsert it. Wouldn't work the other way.
I thought it was fixed, then it rained all weekend. Got in the car, it was worse than before. I tried the windshield, i tried the door.... tried the sunroof drain again. I could see the water coming out the sunroof drain outside the body, draining right on the hood release cable, and coming back into the interior dripping on the carpet.
The solution was to pull the drivers mud guard off, pull the fender liner half off and on the hood release cable a few inches from the body was ....a hood release cable rubber grommet. The fix was 2 problems. Put some grease on the rubber because it was a bit of a pain to get in due to contortions and tight space.
Wet This is the 90 degree rubber grommet tube that the sunroof hose is supposed to be connected to. Grommet removed, you can see the sunroof drain on the top left. This is looking up from the driver wheel well behind the fender. The hood release cable goes through that hole and you can see the rubber has come out. Above it is where the sunroof hose grommet is supposed to stick out and drain.
Holy crap! My driver's carpet was always getting wet and I couldn't figure out why. Turns out, my drain tube is completely disconnected from that rubber grommet!!
Like you said, I took the grommet out but now I can neither put in the drain tube nor the grommet back! Any tips on how you got it all to go back in place? I would just take it to a shop, but I just moved out here and don't even know if a shop would entertain this lol
for the drain tube i -
took the L shaped grommet off the car,
put it on the tube,
and then put it back on the car while attached to the tube.
Working on this! I took the L shaped grommet off, but struggling to even get the tube in. Finally got it in once, but couldn't get the grommet to extend enough to get back in its spot.
Will try again though. Thanks a lot for the write-up!

I can't for the life of me get this back in place! I took the grommet off. I can barely get the tube in. But after it's in, I can't seem to extend the grommet enough for it to go back in place without the tube coming back out. Any tips you can share? I'd literally pay someone to get this done for me!
i tugged on the tube a bit just to straighten it out, and put a little grease on the area where it connects to the body so it went in without fussing with it.
Hey you all, been incredibly guilty of lurking and not contributing anything worth while in... awhile. I saw this thread and had to chime in!
I went through this same aggravation recently, beginning with noticing my driver side floor mat getting wetter and wetter. I took it to my local mechanic who could not deduce it, then ultimately coughed up the $150 diagnostic from a Honda dealership to get the true problem (they gave me a free loaner for 4 days so i considered it a wash!). Honda told me I was looking at $1000+ fix because they traced it to it likely being the drain tubes in the 4 corners of where the sunroof is and they recommended replacing ALL 4 because of my mileage (276K). This was such an expensive job because it consisted of taking out the whole headliner.
So I'm at a cross roads- I've entertained moving on to another daily driver but figured what the hell, what do I have to lose. I toyed with the idea of just caulking the damn sunroof shut but as a last ditch effort, I thought outside the box. That my friends is the use of an ear plug. Long story short, I've had it in place the last month and a half and no more water. I have checked on it numerous times and yes the water does pool but ultimately goes to the right drain with no leaks. Pictures below as well as updated pics of the beater!
I had to chime in because this forum is so valuable and have appreciated everyone's contributions the last... 13 years and almost 200K (my addition) miles of ownership. Hope this helps!
PS- another PSA, my bottom side skirt had paint chipping but nothing a little Matte Black wrap didn't fix. Also, picked up these RH's with used tires online for $500!
I see...so the seal around your moonroof is allowing water into it, but the drain tubes allow a route for the water to escape the inner portion of the moonroof assembly AND you plugged the drain tube that was leaking into the car?
Water is still allowed to escape through another tube?
