I have clear, clean water leaking into the passenger side footwell. It's coming down both sides of the footwell:
Here you can see where the drops are falling from:
And here is an indication of just how much water is making its way inside the car:
I'm familiar with the AC vents getting blocked and causing water to drip down the side of the transmission tunnel but not so familiar with the leak on the other side of the footwell. I'm also doubtful that the AC drain would produce that much water over the course of a 20 minute minute journey.
The cleanliness of the water and the fact it's on both sides leads me to think it's not the heater matrix O-rings leaking.
I've only noticed it when it rains, which it has been doing a lot over the last few days,
Are there any common/known culprits for a leak like this or do I need to start stripping out bits of dashboard and pointing the hose at the car?
