1995 d21 :I have wet carpet on the drivers side floor pan, so i pull the carpet up,dry it out, put it back down and after the first lot of rain it is wet again,so up with the carpet again,get the wife out side with the hose and run over front screen and drivers door after 15 min no water inside ??????. carpet was more wet on the door side of the pan so i don't think it is the heater core. any one have any ideas or things thay have found in the past. thanks des
