I have a 1990 Toyota Corolla Hatchback (AE92). I left my car at a mates for a few months so he could fix a few engine problems whilst I was overseas. The car was not driven and was left outside. After some rain, my mate told me the floor of the drivers side had a big pool of water in it, and I saw this too. He seems to think some sort of drain hole is blocked, does anyone know how to fix this? He mentioned the front right wheel arch to be unscrewed and drain holes cleared? We ran out of time to check this.
