Hey all,

re: 2004 TSX. Outside parking.

A couple of times, day after really heavy or long-duration rains, got in the car, pulled-out the seat belt and found that it (lap belt/shoulder belt) was wet, mostly where it had been retracted and hidden inside the vertical interior cover (behind the male buckle that catches there).

Also, haven't been using the car so much in the recent past, so not sure if things dried somewhat before discovery.

Would appreciate any comment on where to look for a possible leak.

Did not notice any other moisture in the interior, and "rubber" weatherstripping seems intact (although from searching online, apparently I should have been periodically refreshing it with Honda's extra-special silicone grease . . .)

Thanks.

Won't be around to check them physically for a while yet, but more web-searching calls attention to a general problem with roof-drains.

It seems A-pillar leaks are common due to front moonroof drains clogging or becoming disconnected. And looks like in most cars the tubes from the (semi-hidden) rear drains route through the C-pillar.

So, would anyone know if the TSX rear drain-tubes go through the B-pillar? Or if a drain clog or disconnect can display as B-pillar leakage?

(had to reply as couldn't edit post)

Concur with roof drain channel, especially with a wet seatbelt. I had this recently with our Odyssey on pax side. The black roof trim is just a cover for the channel. Get a new set of covers as they're likely well worn along with the plastic retainers (retainers might break when pulling up the trim). Then get some Permatex adhesive silicone sealant ( https://www.permatex.com/products/ad...-sealant-3-oz/ ) -- comes in clear or black, I used clear, Walmart had it. After the trim is off and you clean it out, you can see/feel the metal to metal seam. Lay down a bead of RTV and used a gloved finger to press it in. After it was back together, we left the van out to test. A week later we got a huge rain and everything stayed dry.

There are some utoob vids out there that can show you, but also some that do it wrong, like the one guy that fill the channel up with RTV.
