I've got a Grandam that I've been working on that leaks rain water onto the floors. I took the heater core area apart today in hopes that it was just a plugged drain but no luck there. And actually there was very little water in that area compared to the serveral gallons on the floor that was vacuumed up with a shop vac. While apart I can see that it is wetter on the insulation next to the firewall than anywhere else and it appears that the water is coming from somewhere near the base of the windshield but not sure where. Does anyone here have any ideas ? It looks like it's been doing it for quite a while as everything is pretty damp and it never dries out.
Let me know... Thanks, Steve m...
