Water on floor of car back seat.
We first noticed the problem when a friend sat in the back and got a wet bum.
This car was getting wet on the right hand rear seat behind the driver.
Your first order of business is to get as much water out of your car as possible as quickly as you can.
Water will always flow towards the back seat because it sits lower than any other part of the car.
Rain water goes down inside the door at the bottom of the glass and that vapor barrier directs the water flow to a drain at the bottom front of the door.
I recommend you check the front carpet under the floor mats and the trunk in the spare tire well and surrounding area for any water or wetness this will indicate where the water is coming from that would be the first step and will prevent you.
The heater core is like a little radiator which water passes through under the dashboard to heat the cabin.
Check to see whether the liquid collecting in the car is antifreeze or water don t taste it.
I stripped the interior out and found a pool of water under the rear bench on the right hand side unsurprisingly and the seat foam was pretty wet too.
If your floorboards have an inch or more of standing water you ll want to use a wet dry vac to suck it out taking particular care to get into the nooks and crannies between the seats center console and armrests.
If you are experiencing water on the passenger side floor of your car or truck and if it s not antifreeze 99 of the time it is a simple fix.
Another good indication is if the liquid is only collecting on the passenger side where most heater cores are located.
