The usual suspects are a cowl vent screw, antenna grommet or the wire loom boot that goes to the door. Pull the side kick panel and put some water on it to see if it’s leaking past that boot.
One of the screws that holds the black cowl vent panel down goes in right above the blower. Pull the blower, stick a mirror in and you’ll see it. They’re just self-tapping screws, goop it with RTV and that usually does the trick.
The antenna passes through the passenger firewall and has a rubber grommet. Mine has leaked there before.
Also, there is painted body seam filler in the area near the hood hinge where the windshield meets. It cracks over time, either coat it with something like flex seal or flowable silicone to seal those up.
