OK I guess it is worthwhile to mention the vehicle is LHD and there is no sunroof. The cabin air intake/filter is on the right/passenger side and that side is completely dry. So far I have checked the door panel card and it is not leaking water in. The drains under the plastic windshield cowl/cover is clean and water does not accumulate there.
I realized there was so much water at driver's side that it was almost 1m above the carpet. It was like a swimming pool there. I drained it slowly using towels, it took at least 3 fully wet towels. But it rained yesterday quite a bit and it was full of water again.
I checked some other forum posts and seems like one possible cause is the hood release cable location. But I do not want to remove the cowl plastic right now as it is like 2C outside. I will try to check it from inside if possible.ook for?
I wanted to make a list of things to check before starting to look around and start from easiest to check. So, any ideas on what else to add to my list?
