When it rains heavily, water somehow is getting in my car from behind the glovebox. It causes sometime 1-2 inches on water on floorboard. I had the windsheild on passenger side resealed & still having issues. Can't locate problem & I want to not waste money for troubleshooting. Anyone ever come across this problem & fix it!

I have the same issue. My windshield has been replaced. The water is coming out of the ventilation through the fan.

Never had the windshield replaced just resealed on the passenger side.

Were you able to fix the leaking problem after you pinpointed where it was coming from-ie ventilation area?

I haven't pinpointed the source, only the place it is coming into the passenger compartment. I was hoping someone here might have seen the same issue and know where the problem might be.

I have tried resealing the windshield as well. No luck. I suspect the water is coming in through the ventilation system via the ductwork below the windshield under the hood. It must be coming in from above the fan because it comes in when the car is parked. That elimnates road spray as a cause.

My electrical issues have to do with the vent fan shorting out. I have a blown fuse in the fan. When replacing the fuse, I only have setting 5 on the control. The Hanes manual indicates another fuse in the control system that is not in any of the fuse blocks.

Can anyone shed some light on our problem? Any more testimonials?

The water isn't coming through the windshield. It's coming through the molding down below.

At the bottom of the windshield, there is a rubber piece that fits around the bottom of the glass. This piece lays on top of a plastic piece that is held down to the metal of the cowel by fastners. I pulled these fasteners and looked under the plastic piece. I saw the top of the fan.

The problem I had was that the rubber modling was not laying on top of the plastic cover. I reglued the rubber to the windshield glass with silicon glue. I then glued it down to the plastic cover.

OK, maybe it was overkill, but my floor is dry and I was able to get the fan running. I now know where to find the fuse, and I know where the water is coming in.
