126 with water (alot) under drivers mat

[jeffoc]

I have a 89 300se and this weekend I was cleaning out the back seat and I noticed water on the floor, enough that the water was above the level of the carpet. Investigating further I found water under the front mat as well, just under the drivers side front and back.
Doing a forum search I found out about the drain holes and have checked them, they all seem ok but I dont know for sure yet, We have'nt had any rain since. The water is clean so I know it is coming from the outside. The rest of my question is that the blower fan had quit working 2 days before I noticed the water. No warning or noise just out of the blue. I just found out about the fuse outside the box and have not checked it yet. Is it possible that these things are connected or do you think just a coincidence. No one has ridden in the back seat for a couple months and with the rubber mats I have in the front that water could have been there since August.
Any thoughts are greatly appreciated
