Default Leaking Convertible

I have a minor but annoying leak at the A pillar where the top meets the windshield. The velvet looking trim which is supposed to be sealed against the rubber seal, it weeps and then drips onto the seat. I've searched the forum and read a couple of posts. Found some things to check but, I'm still looking for help. it rained for about 15 days here and then a couple of days break and guess what? it's raining again. Any ideas will be surely appreciated.

Have you tried to replace that rubber seal there under the velvet? Try going in realoem.com to find the part number. I would look there first to get an idea of all the parts and possible leak spots.

I sealed it using a clear adhesive sealant which you can get at any auto parts store. Open top, apply sealant, close top.

I had the same issue. If you look at the seal there is a part that cracks...think it is adhesive between it that actually cracks but it looks like a triangle almost. I can snap a shot later today after I wash my car. Give me a few hours. I sealed that back up and my problem is solved. The other issue I had is a small tear that i repaired with rtv. You can't even tell now.

Ignore all the dirt and dust stuck to it but I sealed around this area. The small Crack at the top was not the issue but the seal was broken around the triangular insert. This solved the leak. The other solution is a new OEM seal which I plan on doing if it leaks again. I used black RTV.

Question Re: Leaking Convertible

I'm thinking of the same RTV fix but where ? It is not easy to find the problem. Can you post some photos of where you RTVd the corners ?
Thanks

I have water accumatling in the trunk section on top of both of those black plastic covers. The one for the battery and the one on the driver side. Rest of the area is dry. Is this from the tail lights? Not sure if this is vert specific

From my experience, underneath the top where the C pillar meets the body, there are drain holes pretty good size ones. The drains are right above the areas where you're getting that water. You have to put the top down to see them. Check and make sure the drains holes are clear and free of debris.
