Im not sure where to post this but i hope someone responds, i had my car checked last week, then after three days, i noticed water seeping on my passenger floor, a friend told me it might be my air filter and it was coming from the air filter. I want to replace it, i found this on the net, a video on how to replace cabin air filter. Do you guys think this can be done to a honda?

 

if water is coming in on ur floor board then it mey be ur heater core leaking, check ur water level in ur radiator

 

Theres a rubber drain hose on the passenger side that leads out towards your engine bay. Sometimes that gets clogged so instead of draining out the hose, water just dumps out into your passenger floorboard. Look up underneath the dash for it and take it off.

On my car I took the hose off, cleaned it out, and then stuck a wire hanger into the opening and dug around. I had leaves, twigs, and a bunch of water pour out. After that I put the hose back on and have not had a problem since.
