After heavy rain I noticed a lot of water soaked in the rear leftside passenger footwell. I pulled the rear interior out and got my partner to hose it down while I sat inside and checked for leaks, couldnt find one. I left the interior out and monitored it after a drive, water was there again, pooled on the body where the seat would sit and had ran down to the carpet yet again. Turns out the water is getting into the body and pooling up, coming out a hole in the side next to the rear door (I'll add a picture link). I had a rag in there, on taking it out a stream of water came out. Has anyone had this problem? Im guessing there is meant to be a drain hole in that compartment to let the water out, which has now blocked. What do others think?
I hope this helps anyone having a similar issue and cant figure out where it is coming from.
