2001 water leak in roof

:confused: 2001 grand prix wide track 3.8 n/s gt. has sun roof and no on-star when it rains real bad here water will drip from my map light. slow drop every few minutes i opened the sun roof and didn't see any debris also the sunroof does not seem to be leaking wher could the water get in from thanks

Sounds like your sun roof gasket is leaking it in.
Also your drains have hoses up in the headliner, if they crack(and your gasket leaks) it'll leak and run into all sorts of odd places.

Where are these drains in the headliner at and how do i go about cleaning them thanks

one of the drains is in the front passenger side corner of the sunroof assembly, and runs to the passenger side A-pillar (the metal part between the windshield and front door) to the ground. The other is in the rear drivers side corner and runs to the drivers side B-pillar (the metal part behind the drivers side door). Make sure these drains are clear of debris, or they will allow water to pool up and come out where you don't want it to.
