04 GP Roof leaking

Just bought an '04 GTP Comp G. I'm really happy with the car so far except that I ran the car through the car wash today and I got a small stream of water that came out in between the dome lights (I have a sunroof). The water does not appear to have come in around the sunroof seal so based on where the water entered I suspect the base around the OnStar antenna (small, stubby antenna on roof behind windshield but in front of sunroof - OnStar? vehicle has OnStar and XM) may be deteriorated allowing water to get in. I hope that is it and not the windshield leaking.

How do I get the bezel around the dome lights off to gain access to the inside of the roof? I think if I get in there I can probably get the antenna up and maybe buy a new gasket for around it or at least use some silicon sealant.

I also want to find if there is any damage from previous leaks up there. I did notice the headliner is slightly stained around the dome light bezel in between the sun visors.

Thanks!

This is a known problem. That is the Onstar antenna upfront, the XM antenna is on the back of the roof. There is a bad seal on the Onstar antenna that is causing that leak.

My Comp G was fixed at the dealership before I bought it, but as far as I can remember the previous owner said he paid nothing for the repair. I hope that is the case for you, usually a mistake like this is covered.

thanks but I don't think the dealer would cover this. It's out of warrenty and I bought it off a used car lot. I took everything apart tonight and it is a pretty poor design. I'm reverse engineering it and will get it straight.

Same thing with my 04. How did you get the light area off?
