Having problems with your 2004 Pontiac Grand Prix ?

Whenever it rains, my floor becomes soaked with water. It occurs predominately on the passenger side and floods all the way to the backseat. I know this problems is not any way associated with the air conditioner. A fellow grand prix owner told me they experienced the same problem and it had to do with a seal in the front....any suggestions?

Answers :

Contact you local GM dealer. They will have a few updated parts to sell you that will take care of this. I think there is a rubber diverter, possibly a plastic shroud, and possible a new cowl cover.
