Kouki SE sunroof, wet floor board

[Zumin]

I have a 1997 SE with sunroof. I've tried searching, but I get nothing but the usual "check your heater core" etc, well the smell isn't sweet and it's right in my passenger footwell. I don't notice this until I lifted up my factory floor mats and noticed the carpet was soaked. I'm wondering if the sunroof has a drain? Possible runs down the A pillar and down the passenger kick panel? Could it be the condensation overflow drain in the AC is just clogged?

I'm not sure if the s14 is prone to any of these, I know all chassis are different, so I'm trying to keep from chasing dead ends.

It will either be a clogged condensation drain if you still have AC or your heater core most likely.

Check your coolant- If you're losing it, then there ua go.

Stick your hand up behind your glove box... Feel around & see if you can isolate the leak.

Take the car thru a carwash and shine a light down in the passenger footwell while it's in there... If it leaks, figure out from where.
