While driving today, I stop at a red light and some flickering at the right corner of my eyes...

WATER!

The floor of the passenger side had a good ammount of water.

I have no idea how it got there. It rains yesterday... But how did it manage to go inside the car!? The doors seals seam ok. The bottom window seal is really in bad shape, but I wasn't expecting water could enter that way.

Is the bottom window seal a specific part or any window seal could do?

Or is the water getting in from a totally different place?

I put the car under cover... More water would mean it could get to the fuse box. Bad stuff might result.

I had water in the passenger side footwell a couple years ago. It came in through the seal under the heater fan. Dripped right on the passengers foot. Repaired the seal and screw clip and all is good now.

its usually the blower box thats leaking to confirm get a light and look up under the dash keep the CE panel; door closed, after this inspection the open the CE panel and check for corroded relays and fuses, disconnect the battery before you work on the CE panel

As above, its probably coming in through the blower box seal

The drain hole from that area is probably blocked - leaves and other stuff pile up under the blower and eventually block it. You can poke the rubber "trunk" that sticks out through the firewall there from underneath the car to drain more out - careful not to get a face full of filthy water.

thats what happened to my 82, cleaned it out and not more issue. Very hard to get to with the engine in the car.

linderpat

is your engine out of the car?

I took this photo while parting a 79, was the best way to illustrate location and problem

The drain hole is accessible, more or less from underneath the car. I never had such a leak but got in there to clean it while I was under the car doing other fun things.

Don't forget the eye protection.
