water leak in cab!!!

SO I havent driven my car in awhile. I cleaned and vacuumed out the inside the other day and found out that my floor was really wet on the drivers side kinda by my pedals! where could the leak be coming from? I vacuumed up everything by the air cals infront of the window and that didnt do it.

Does it smell like antifreeze, or just straight water? I wonder if fluid could go from the heater core through the duct. Otheriwse, maybe a leaky seal between the steering shaft and firewall (or other grommet there) or windshield leak.

My guess would be windshield.  My 88's windshield actually came un-stuck from its frame, something I didn't notice until I took the windshield trim off to paint the car. With the trim off you could push the left hand side of the glass 1/2 inch away from the body. Yes, the glass was actually bending. I ended up having the windshield replaced, since it was starting to delaminate in the corners anyway...

Maybe the sheet metal has a hole under the cowl or the windshield could be leaking at the bottom.

run water on the drivers side of the car with a garden hose and look for where the water is coming in at with a shop light under the dash

Bet it is the HOOD RELEASE CABLE where it goes through the fire wall. Unless the windshield separated. Look at the grommet that is the most likely spot. Fixed several that leaked where you are talking about.

Moon or sunroof?
If so....the corner hoses are plugged, if no window in the roof, then the aforementioned places must be leaking.

I thought the roof drains were in the rear of the coupe by the FLAG panels. Not 100% on this though. Good point though!!

That's got to be it.  I had a difficult-to-find leak on my 88 that was exactly there.  It had annoyed the PO who added a bunch of goop to the windshield to try to "seal" the leak there, but to no avial.  The drain for the windshield behind the DS fender is DIRECTLY above this grommet.  I pulled the fender out a bit and put some rubber (from an innertube) and rubberized adhesive above this grommet as an eave to force the water away from this point.  I'd try that first.

Found it! the black metal thing at the bottom of the window is very loose. On the driver side there is a huge gap between the window and that black piece of metal. How can i fix it? I live in the NW and its been raining ALOT here.

Take a photo. I am thinking i know what you mean and that might not be the issue. If memory serves me the window has an over hang and that plate is not to keep water out. Just saying.

I'll take a pic of it tomorrow. Along the rest of the window that black piece of metal is up close.
