Hey guys I have a 2004 Pontiac Grand Prix GTP with the sunroof. We have noticed on big rains that the floor is soaked both on the driver side and the passenger side, our first instinct was to look at the windshield as see if it was leaky. We went to gerber collision and glass and they took a look at it and responded that the windshield seals were fine but the sunroof does have drainage pipes leading through the roof of the car and down the a-pillars. After that comment was made we took a look at the roof and noticed water damage around the sunroof area and some on the a-pillars. Does anyone know how to clean out these drainage areas? Any help is appreciated.
