Moonroof sprung a leak -- replace weatherstripping?
Hey guys. I just realized today that my moonroof is leaking. What's the best way to take care of this? Is it possible to replace the weatherstripping? Condition it? I tried searching but didn't find anything definitive. Thanks.

Just pour water on the sides of the sunroof, if the water doesnt flow then know that you have blockage in your drains. Running water also helps clean them out. If you do have stubborn blockage you can probably use a thin electrical wire and snake it down the tubes. Or maybe compressed air

OK, I just checked. All four drain tubes are clear. The water pours straight through them. What's strange is that I only have the problem when the sunshade is closed. The water tends to accumulate on the front lip of the sunshade. Is it possible that the sunshade extends too far forward and prevents the water from reaching the channel in the front?

Same thing is happening to me. I found a few threads recommending Shin Etsu grease to condition/restore the rubber and it 'plumps' it up to seal better. My sunroof isn't leaking bad so I expect this may work. I applied it yesterday and now just waiting for a rainy day so I'll keep you posted.

Where do you get Shin Etsu grease? Also, assuming the drain tubes do their job, then it would seem that it's okay for water to get past the seal, right? The only time I see water is when the sun shade is closed. Otherwise, I believe the water is going though the channel and out through the drain tubes.

You can buy it on Amazon for $17 or give your local Honda dealer a call. I picked some up at Honda for $19 in their parts department.

i don't think so and here's why. When I felt the water collecting on the underside of the lip on the front of the sunshade, the front channel was completely dry. Like I said, it's almost as if the sunshade, when closed, is catching the water in it and not allowing it to reach the channel and drain out. I've never had any water dripping in my car with the sunshade open.

If my theory is correct, it's one of those things that I would never have noticed unless I closed the sunshade. With the sunshade open, any water that gets past the seal would drain out correctly through the drain tubes.

Bumping an old thread. We had a heavy rain in Chicago today and water was dripping in through the plastic trim piece directly above the rear view mirror. Now in fairness, my sunroof shade was partially closed so that may have been the culprit for the reasons described above.
I checked again and the drain tubes are functioning properly. I just can’t figure out why water that is getting past the moonroof seal isn’t channeled directly to the drain tubes and is instead somehow collecting above the plastic piece just above the rear view mirror. Makes no sense.
