I have a leak coming from various areas of inside the car. Water drips down from the interior roof of the car. After it rains I smell mildew and I have see water come out from areas in the roof and the interior light. It does have a sunroof and I do not see any obvious leaks? 2006 gtp
Anyone else have any experience with this?

Two most likely scenarios are a plugged/kinked drain tube OR a disconnected drain tube.......
Easy to check
Jack up the rear of the car....open sunroof......with water bottle and funnel.....add water slowly to rf corner of sunroof water tray.......water should not build up...if it does, then tube kinked/plugged....if it drops, should come out immediately out of the bottom of the "A" pillar....if it doesn't, and comes out of headliner or switch, then tube on that side is disconnected.....then try opposite side......then jack the front up and do the same test to the rear corners....

Agreed, I have seen several with the drain tube off the the sunroof, usually the r/f. Will have to partially drop the right side of the headliner to access the hose to reattatch. I have also applied a little rtv to the hose to help it stay attatched.
