I am finding water on the floor behind the drivers seat. I use a shop vac to clean it up, but by the next day there is water there again. The car is kept inside a garage at night, so I am curious as to where the water is coming from. I have tried running a hose along the edge of the door and it doesn't seem to leak anywhere there. We do have a sun roof but that doesn't seem to be the problem either. Are there any drain hoses that run along the inside of the door frame that could be clogged or broken?

Thanks for any help you can give.

The sunroof has a drain in it. Open it and make sure it isn't plugged. Also, if you are using the AC, make sure the drain is not plugged. Usually, a plugged AC drain will cause a leak into the pass side front, but stranger things have happened.

What about passenger side rear on the drivers side? The floor in front on the drivers side is dry, just the rear is wet?

The door usually isn't the issue.
