Pull the passenger side kick panel. Possible the ECU is located there,not something you want to get wet. Lift the carpet up on the passenger side. Take a garden hose and apply water - 1 - The cowl area just below the windshield where the plastic guard is. 2 - run water between the windshield & the seal. ( possible windshield frame is rusted) 3 - run water - (lower area) - the gap between the door and fender. Behind the lower part of fender it's common to find rust holes. Dirt can build up in this area and water can back up. When you have the kick panel off,make sure the lower area isn't rusted out. If the AC drain hose is plugged it's possible over a period of time water can accumulate to the point where it leaks on the carpet. Does the water accumulate on the carpet when the truck is sitting or being driven or both? Also check the bottom of the door for rust holes. Water should run out the drain holes. A heavy rain could allow water into the cab area.
