08 Grand prix leaking roof

Hello, it rained last night and this morning i noticed my cupholders between the passenger and driver seats had water in it.
the car was parked at in incline on my driveway, the front facing up.
the leak looks like it was at the dome light right above the cup holders, so the leak would have to be somewhere up front.
I read another post with a guy with an 04 that had a leaky onstar antenna that did the same thing. My car also has Onstar. Do you think this is the issue? I do not have a sunroof or anything.
thanks for your help.
I dont even know where the onstar antenna would be? i have the antenna in the rear, but that's for the radio i think, i have the standard radio/cd player, no xm.
or could it be a leaky winshield seal?

my 04 had the same thing, i took the headliner off and one of the draining hoses had come loose, so when it rained it just leaked and came through the light, it either that or u have a hose that is clogged.
 
I have a coworker that is having this issue. He has a 2005 GT that is leaking when raining but just dripping. He doesn't have a sunroof. Is there a gasket on these things ? Were thinking its the onstar antenna.
