Default Re: Water leak in passenger area SC2

If you are making a new gasket the material used needs to be closed cell foam. After all, It's not supposed to allow water through.

In the case of a ripped/torn gasket I've used acoustic caulking to adhese and seal it all up again. It's messy but it works.

The other possibility would be the HVAC drain on the firewall is clogged. The A/C evaporator within the HVAC behind the dash has a drain that exits through the firewall. This allows any condensation from the evaporator to drip down and exit the interior and drip onto the ground. You can use a pen or pencil to poke into the drain and unclog it. You'd need to access it from under the car.

Here' a video >>https://www.youtube.com/watch?v=W0VdFRDdgvA and a photo of the drain location.
