I just bought a Mazda Protégé 2002 and a few weeks later I noticed a damp spot on the back passenger side floor. Very wet and soaked. Later I noticed the smell grew larger and the vapor on the glass grew heavier. I then noticed the water was also in the front passenger side. I used a vacuum and soaked about a cup of dirty "water" can't tell if it's water or a leak from within.
Any ideas on removing this water, if it was because of the rain? Or where to look if the liquid came from a leak from within the car?
Edit: also the water reaches to the trunk and all areas is just the right side, passenger side
