I got my 04 gtp 6 days ago - yesterday we had heavy rain - last night when i was making a turn I felt a drop of water hit me - then a minute later another drop - I thought the sunroof was leaking but i opened it and felt all around the edge / lip / and inner rim but nothing was wet. Then a little later i felt another drip. I saw the drop cominh out of the dome ligh next to the sunroof switch - so again I open the roof and look fown from above and all is dry (weird). Sinve it rained last night I went out to look this morning and I see a few drips next to the huf contol nd another drip hangin down from the overhead light again. Now I wondering if this could be coming from the onstar antenna? Does anyone else here have a similar problem or have heard of a solution.

UPDATE - after further inspection I see that the headliner closer to the windshield is wet around the domelights so I'm wondering if the problem is the windsheild???
