I have a 2000 Ram and it leaks rain water inside the cab on the passenger side floor board near the kick panel. It's not a heater core leak, windshield has been replaced and that's not the problem. All the door seals and glass seals have been checked and they are not the source of the leak. I've narrowed the search down after removing the wipers and plastic cowl cover to somewhere in near the passenger far back corner of the cowl. An area impossible to see or reach, has anyone else had this porblem and if so what was their method to correct this issue?? Thanks for everyones time, please respond with some advice.

 

I think you and I have the same problem. My truck is a 1998 ram 1500 2 wheel drive quad cab. I found this and it may be your problem. It didnt help me but it might help you. Hope so. http://dodgeram.info/tsb/1997/23-68-97.htm
