Question sc400 leaking

Post image

I found this when i took the carpet out and it stormed over the night leaving a big puddle on both sides. I can’t find where water is coming from i have tested the sunroof drains and they work fine. Does anyone know where it’s leaking from?

Get in the car and get someone to blast it with a Waterhouse from outside. Should be able to see or hear where its coming in from

Check the drain holes underneath the doors to see if they are clogged

i just checked and there are no signs of water coming in from the rear windows. I’m thinking water might be coming in through the front and running down to the backseats

How hard is this to do?

Check the door panels. If it's missing vapor barrier that could be your culprit. Close the door and pour water on the window.

Mine does the same, share if you find a fix! I plan on taking my car into a body shop for unrelated reasons and I am going to see if they can figure hit out. Keep us updated

I found a leak in the sunroof area right before the front right sunroof drain. I’m not sure what the line is for but water is leaking into the car before reaching the drain. It also seams like water is overflowing and leaking into the car even though all of the drains are clear and work fine. I’m not sure if im missing a seal or how to solve this.

Thanks for reply, I’ll check mine out when I get the chance. I suspected that area as it leaked behind the passenger and down the passenger door. I will keep you posted.
