Not too long ago, i had my Ej 4 door swaped. I noticed that before I had the swap, there was no leak/driver floor isn't wet. Now, when it rain my car would get wet floor after driving. I check the moon roof, pour some water down the drain hole and no leak. Is there other place that I can check? I really have no clue. Also, today it rained a little, but there isnt any leak!? I know its an old topic.

 

Its wet on the driver side? Wet on the passenger side would be heater core.

 

Could be doors, windows seals or your hood seal

 

Also check your under fender covers, they might have moved.

 

Thanks for the reply :D. Mainly, its wet on the driver side. However, it also wet (a little) on the passenger side. As of yesterday, it rained again, not wet inside?

 

make sure your A/C drain is not clogged as well, it exits on the passenger side but can leak on both sides
