Water does not collect in the back, just the front. The more rain we get, the more water in cab. It almost seems to be coming in from the bottom of the doors. Have tried to seal this area, no luck. Have tried to seal other areas such as windshield, rearview mirrors, etc. Have heard that it could be A/C unit but it is flooded on both sides. Really need some ideas and no $$ to go to shop.
The cab of my truck is flooding on both pass and driver side. on 1996 Dodge Ram 2500
poss your a/c evap drain is plugged and overflowing into trk.look under heater box under trk and take a air hose and litely blow air thru the tube hole and see if a blast of drain water comes out
