Thread: New to group - leaking factory sunroof

Hello,
I'm new to the group and was looking for some help. I have an 05 GTP and I find that my factory sunroof leaks. I've had the car since new and no problems until recently. Any suggestions? Thanks

sometimes the drain pipes that drain the water away between the roof panel and headliner get clogged...also it could be around your onstar antenna since these things are known to leak( I beleave if it is this you will have water leaking near the reading lamps...)

Water is coming in at the reading lamps. Headliner is also wet and starting to stain. I've looked and can't seem to find what I think would be the drain pipes. There are tubes sticking up but I can't imagine they would be used to drain water. Where would the drain pipes be located?

call mr chatman,1-866-932-4368, ext 38747,when my nose on my 01 started showing yellow thru the paint,he called a dealer for me and it was painted the next day,no charge..

I beleave they run down near the rear pillers, I cant be certain thoguh but I can find out in my service manual tonight...I would also remove the map light assembly and spray water around the onstar antenna to see if that could also be leaking since I have heard of that happening alot and the onstar antenna is right above the reading lamps or almost there.

Thanks for all the suggestions. I suspect the OnStar since water is coming through reading lamps and surrounding headliner. Also, I noticed that it seems to be slightly loose and not sealed properly towards the sunroof side.
