Acura Legend Water On Passenger Floor

Reader Question: Austin,

I have a question!

I have just bought a 1995 Acura Legend. I just noticed water (moisture) on the passenger side floorboard. Really a lot under the seat area (I ran my fingers across it and it seems to be clear w/o an odor).

It also seems to create fog/moisture on my windows when I am riding with the heater on. Moisture/fog is always on my car windows even when the car is sitting. I guess maybe after driving with the heater on (I never noticed).

Can you tell me what this problem could be? What could cause this? What should I check? Could this be a serious problem?

Thanks,

Marcus

Hey there Marcus,

I would check the antifreeze level inside the radiator to see if you are low, and to see if there is just clear plain water in the radiator. You could have a heater core leaking antifreeze or in your case maybe just plain water on the passenger floorboard. Usually the heater leaks up under the carpet under the dash on the passenger side where your feet would be if you extended them as you were sitting in the seat.

If the radiator is full of green antifreeze, you might have a water leak around the windshield weather stripping or the passenger window or sunroof if you have one. I would visit the local manual car wash and have someone sit inside the vehicle as you spray around those areas with the high-pressure sprayer.

Here is more information about heater core leaks –
