89 Integra water leak

There is water soaking my back seat, both rear floor boards and hatch area. Cannot find source of problem. Any suggestions. Thanks for your help.

Mix up some soapy water in a bucket, set the vents to fresh air, turn the blower on high, close the car up tight, and slop it with the soap solution...it'll start blowing bubbles from wherever air is blowing out (and presumably where the water is getting in...)

The soap thing is genious...I would have never thought of it. I'm totally going to try it for my integra!

If you have access to compressed air, you can direct it at the inside perimeter of windows and doors with soapy water outside too, just don't get too crazy with it. Don't wanna blow the perimeter seals apart...

If you do it just by using the heater blower, it can take several minutes to start blowing bubbles...be patient.
