Hi, I have a 2003 Honda Accord and today I noticed water leaking under
the car between the driver's and passenger's seat. The engine was hot
from driving but the water was cold with no color at all - it was plain
old water. I drove over no puddles and I was not running the AC so it
can't be condesation. Does anyone have any thoughts on what to look
at? If it's the water pump, wouldn't the water be hot? Thanks

If it was the water pump, the fluid would be colored with coolant
(probably green).

If you were defogging the windows just prior, the AC will come on
automatically to dehumidify the air. It may be this you were seeing.

I'll go with what tegger said, if the defrost was on at all or, you
had the climate control on auto, the air conditioner could have been
running, just not pumping cold air and would have given you the
condensed water.

Or the AC drain has been plugged and just started leaking.

As has been said, Honda chose to automatically turn on the air conditioning
when you have the air flow setting at either full defrost (all on the
windshield) or partial defrost. However, they also chose to not light the
green AC light when this occurs.

Most modern cars operate this way in order to dehumidify the incoming
air which prevents window fogging...

Yes, but why not be up front about it and light the AC light? Or even
better, since the incoming air doesn't always fog the windshield, why not
let ME decide when I need to dehumidify.

I can't answer the first part: why doesn't it light the A/C light? But you
already know the second part - if they don't always dehumidify the air
blowing on the windshield and it should suddenly fog your view, their
liability is too great. I can't think of a single car made in recent years
that doesn't behave that way. Even my '85 Volvo does that. But if you think
about it, if you are trying to remove frost/ice any humidity in the air will
fog (or frost) the windshield as it hits the cold glass, and if you aren't
trying to defog the windshield you need dry air to do that.

Most of the systems also turn off the compressor if the outside temperature
is below a certain temperature, like 50F, because the air is already quite
dry. Maybe that has some bearing on the A/C light status, because trying to
report what is actually happening could be convoluted. "You didn't ask for
the A/C to be on but it is on because you have the defroster turned on but
the compressor isn't running because it is too cold outside." In the end, we
just keep driving unless the windshield fogs up.
