Why would there be water coming up through the carpet on the driver side of my.. on 1998 Pontiac Grand Prix GTP

I jus bought a 1998 pontiac grand prix with 117k miles there's no check engine light on but there's water coming up from the driver side floor making carpet wet.

Possible leak at windshield. Water does funny things when it gets in a vehicle, leak over there but show up over here and vice versa!
Tough to find the actual source sometimes.
