ive had this problem of water collecting behind the passenger seat on the floor. it hasnt happened in a long time. but its been raining the past few days here, and i was messing around today and stuck my hand back there to check it and there was a puddle again. i mopped it up the best i could. my question WHERE IN THE HELL DOES THIS COME FROM??? its inside, and on the bottom of the car, i dont see how rain water could leak into there, nor did i see any holes or anything. could it be from the heater or something?

 

its probley your hatch seal or you can even possibley have a small hole under the car but i could go with replacing the seal on your hatch.happens alot

 

i dont see how it would be a hole under the car, water doesnt drip up.

 

mist and stuff from the tires would build up eventually, ever driven on the highway in the rain? theres a ton of water moving upward towards the bottom of the car

 

true, but i hardly drive it because i dont have my license yet, so that wouldnt be the case. it hasnt gone out of the driveway for like a week.

 

Get the hose out..
Pour it over the car with someone inside and see if he/she inside can find where its comming from.
Buy or look for a new seal or see if you can repair it yourself with some kind of silicone possably?

 

SAiamNE
has it right get someone to pour water on the area of the car where therea re seals such as the hatch (most probably) or door (least probably) and see where she leaks in and then check the condition of the seal in that particular place! Good Luck with your hunt!
