My driverside floor mat keeps on getting wet. The factory carpet not the one i put on. if the car is parked it doesn't get wet....But when i like drive from point A to b i noticed it got wet....i thought the floor panel maybe rusted but it's not...what else can it be..please help me out...thank you very much

 

If you've eliminated any external water getting into the interior, then maybe the heater core is leaking? Usually that leaks onto the passenger side though. Does it happen when the car is running, but not moving?

 

Try treating your door seals with silicone spray.

 

Your drain tube for yor ac may be plugged??? Just a thought.
