Question about 2003 Pontiac Bonneville
Pull your door panels off your doors and check the factory seal on the inside of the doors behind the interior panels. Mine did this and three out of four seals were broken. Held a water hose on outside of door and could see the water running in. Was collecting in the rear floorboard. I reattached factory seal, put some more automotive sealant around that and then caulked around that with clear silicone caulking real good. So far so good. Weather seal around trunk was also leaking and water was collecting in the spare tire well. Might wanna check that too.

The drain hose probably came off the air conditioner, or plugged up. It will be on the firewall on the passenger side. May have to get under car to see it.
