Probably a stinky but almost kinda sweet odor.... right?
That's antifreeze leaking from your heater core. Sometimes leaving the heater off will stop the leak temporarily, but sometimes in November leaving the heater off is not an option, unless you live in Florida. The correct procedure is to replace the core which is a very involved job. The last one I had done required removal of the dash and cost around $500.
You can bypass the heater under the hood but that is only a temporary cure and will disable your heater and then you have two things to fix later, the core and undoing the bypass.

My 2003 Saturn Ion driverside floor board stay soaking wet


Hi Linda , you mite have a windshield leak ! You could possibly look under the dash an see if there is a water stain coming down the metal body inside ! If it were the passenger side I'd say you had a heater core leak .You don't have any unusual odors do you ? Like anti freeze ? Or does the windshield fog up when on defroster ?

The floor behind my passanger seat is always wet. There is not a sweet smell and the water is not sticky. It actually has a slight foul odor, I think it is from the carpet being we so long. I it can'


check under drivers side carpet under fuel pedal, there should be a small black hose which is supposed to run through a hole in the floor to the outside. This is a condensation drain tube. If it is not draining it will follow channels in floor to the back drv side floor well.

I have a 97 jetta when I put the heat on. You could smell the fumes. What can it be.


check the coolant and see if it is low then on the passenger floor board pull the carpet back about where you feet would rest.. and see if the carpet padding is wet. and smells of a odor. then if it is wet you have a heater core leak.and in some case when you turn the heater on the windows will get fogged up

Floor board is wet noticed water around the box thats under the dashboard in the middle between driver and passanger


If it smells like engine coolant, kind of sweet but stinky its your heater core. If it doesnt and it's just wet, the drain for the evaporator (the a/c) is clogged.

Vw polo drivers side floor wet, front and back?


Do you smell a sweet odor? like from the coolant in your radiator?
Your heater core may be leaking coolant into the car.
Or your front window or door seals may be leaking.

Passenger floor wet on s60 volvo 2002?


Sounds like a leaking heater core or faulty hose connections.
Sniff a tissue after blotting some of the wetness or; it may not sound appetizing, but to check if it is coolant + water, take a clean cloth, blot the wet spot and touch the other side of the cloth to your tongue.
Coolant doesn't have a strong odor unless it is hot but it lends a sweetness to the coolant that is easy to detect. That is why one shouldn't dump coolant on the ground since domestic animals will lap it up.
