Water is leaking into my cabin during rainy days and I am confused where it's coming from. The wet spot is around the foothold on the driver's side. I have checked the sunroof drains and know that is not the issue
I agree, probably vapor barrier. I used a black caulk, can't remember the exact name right now but next time I am in the garage I will look, available from your local hardware store. Around $3. Has been dry for a couple of years now.
If the sun roof drains are all open and the hoses are not cracked, I would say its time to remove the door panel(s) and check the moisture barrier. Plastic is either torn or the "caulk" material has a hole it it.
