Question about 2005 Pontiac Grand Prix
The 2005 grand prix model has a known issue with the plastic cowl molding below the front windshield on the passenger side. over time, the sun will cause the plastic to warp and pull away from the windshield; allowing water to run into the engine compartment, into the blower motor, and possibly into the floor of the passengers seat. underneith the warped cowl is a plastic drain pan that is supposed to deflect any water away from the blower motor. It is likely that this plastic drain pan has shifted or popped loose. this is an easy fix.
open the hood, and pull out the three black plastic retaining pins that hold down the cowl. lift off the passenger side cowl and you'll see the plastic drain pan. ensure the pan is pushed tightly against the back and slid all the way to the left. then put the plastic cowl back on and you're done.
also, water leaking into this area is a common cause for the air conditioner blower motor to stop working. So the sooner you fix this problem, the less likely you'll have problems with your blower in the future.

Do you have a sun roof? I imagine you do.
Under the roof cover there is a tube on each side of the car that drains the sunroof area to the ground. Either a tube has been disconnected or come loose. This will cause severe mold and mildew problems if not fixed soon.
