Three things to check for if water is collecting on the drivers side. There are supposed to be rubber closures on the holes underneath the floor carpet, and one may be damaged or not properly in place. The second most likely is the weather stripping along the door, as it may be pinched and not preventing rain entering. The least likely, but third thing to check is at the firewall where the wiring harness enters the passenger compartment.
water in passenger floorboard, where is the hose that would cause this?
A leaky door seal or windshield seal
The heater core has gone bad or possibly a hose leading to it or away from it has gone bad.
A damaged heater core will cause coolant or water to leak onto the passenger floorboard.
Water.
It could possibly be the heater core Check your heatting and a/c
If you left the vent open, or if the vent under the windshield is full of leaves, it could cause rainwater to flow into the floorboard.
because your ovberflow or condenture tube is clogged remove it and just blow it out with air
the ac condensation drain hose is plugged or crimped.
Water from my ac is draining in side the floorboard where is the drain hose on a 99 Oldsmobile intrigue
It sounds like you may have a bad heater coil. Next time you get a puddle, smell it... Chances are it is coolant and not water
I have a water leak in my 2004 Pontiac Montana between the drivers door and theseat,I was told it is the rubber gasket-that's in the floor,where the water drains,outside the Van,is this going to be a big job to repair???
