91 Pontiac Grand Am leaking water inside

#1

I have a 1991 Pontiac Grand Am that has water leaking into the car and soaking the floorboards, front & back. I have checked for obvious culprits like the windshield (using a garden hose), windows and weatherstipping but can’t find leak. Any ideas?

Make Sure It Isn’t Coolant From A Leaking Heater Core And Check Around A Front Antenna (If You’ve Got One)
