We have a 90 Integra,which is having problems when it rains. Water is entering the inside from below the passenger side dashboard. We can't determine exactly where underneath it comes from.

We checked the drains around the sunroof and they seem to be OK, We looked around the windshield, but can't find anything obvious. Running a waterhose ove the top and front part of the car does not seem to do it or we just did not let the water run long enough.

Any ideas where to look next and what other type of test to perform. Thanks all.

 

There are (4) hoses that run from the corners of the sunroof channel down through the “A” and “C” pillars of the car.
Maybe the one on the passenger side front has a hole or blockage in it.

Open the sunroof and pour water directly into the drain hole and see if it comes out under the car where it’s supposed to.

Otherwise, it sounds like a windshield or molding leak by the firewall.

I had that problem on my 88 legend. It was the drain hoses for the sunroof (like Shawn said). They probably just need to be flushed out.
