Hello
so I have been getting water in both passenger side and driver floor carpet. I always keep the sunroof drain and trunk drain holes clean so I know they aren’t the problem. I ran a water hose in the cowl and noticed water coming down to carpet so I know that is the corporate. What should I use to seal it? Im thinking windshield windo weld urethane , you guys know anything better than that? Thanks

 

Keep it in a garage LOL! I guess you have some serious rust happening down in the cowl area. Did you clean out all the leaves and stuff that collect down there on both sides? Its a known area for rot to set in when it's left alone and stuff piles up in there.

 

in your first photo, it appears the seal around your blower vent stack has cracks.

Fyi

 

Is the area slick at all? Antifreeze coolant from the heater core can also leak here and look like a water / rain intrusion problem. When the Heater Control Valve goes out, you'll know it, because every time you hit the gas, the water pump spins up and sprays hot coolant on your gas pedal foot! That'll help your gas mileage considerably until you replace the valve,...

 

its not my heater core or anything like that, thank God .

 

Thank you for the information, Ill take a look.

 

Its all cleaned out now. It was full of debris and leaves like you said. I am going to sand it ad best as i csn snd use a automotive seam urethane. Hope that will work. Thank you
