I have a 94 Rodeo that when it rains ther back seat floor becomes saturated with water. I have checked the floor throughout the truck when this happens and this is the only area affected. The cargo are is dry and so are the front seat floor areas. I have checked for leaks around the windows, checked for cracks in the wheel well somewhere and everyother place that I could imagine. I am unable to locate where the water is getting in or what the source is. I have not driven my car in a couple of days but I went into it the other day ( after several days of rain) and there is water all over the back. I am convinced that the leak is coming from somewhere other than beneath the truck. I have pulled up the carpet and have not been able to tell where the water is entering the backseat. Any suggestions?

Do you have a sunroof/moon roof?

Sorry, forgot to mention that....I do not have a moon/sunroof.

park it up or down hill?

My car sits on fairly level ground. There is no significant incline

weird
I am sure the window is up when its raining right
kidding
how do the door seals look any torn or missing
also check the seal around the windows if one is a bit messed up it can cause this concern

Yes, the windows are up,LOL!
I have checked the seals around the doors and they appear to be good!
Anyone else have any ideas...it is starting to rain again after a long dry summer and the wet back seat floor and "wet" smell doesnt work for me
