Water ingress Accord 2001 - 9000
During the recent heavy rain I have noticed a leak in the passenger footwell. It's not a huge amount but enough to dampen the carpet. I won't have a chance to explore further until the w/e. Before I start messing around with watering cans and torches can anyone suggest a likely source for the leak.

Initial thoughts were in no particular order:

Windscreen seal, pollen filter (I know a blocked filter can cause leaks on other cars not sure about Hondas though), door membrane.

Many thanks 9000.
