First I poured water straight into the intake vents in front of the windshield. They're the ones that have the "grating" (for lack of a better word) over them to catch debris. The water ran straight thru and came our behind the mudflaps. I checked the carpet for an increase in water and it seemed about the same.
Then, I poured water on the lowest edge of the windshield where the glass meets the moulding. I poured it slowly so it wouldn't over run the intakes that are immediately forward. For the most part, the water ran off to the side and then drained, but...the carpet was significantly damper, as in on gray carpet there was a pooling that made the carpet look really saturated/black.
Where is said match to be held?
I've climbed upside down into the driver's side (kids, don't try this at home) and have felt around all over the forward fire wall and I can't find any water anywhere. There are no clean spots in the dust, no apparent leaks, nothing. I can't see any hoses up under the dash that are leaking either. Just water that pools at the lowest edge of the firewall. I even tried pulling the carpet under the clutch/brake/accelerator forward so I could look behind it to see if I was missing anything. No dice. I may have to unscrew the plastic flange that holds the carpet down under the accelerator to check further.
Is there a way for water to run between the forward firewall and the engine compartment to get down to the floor without saturating anything else? I'm totally baffled.
