Cabin water leaks: a Pandora's box of heartache.
-Wiper pivot seals are foam. Take down the pivots from below the cowl area and change the 3/4" foam donuts.
-Windshield trough rusted and or rusted through. Remove the windshield & re-work the metal area. Or temporarily carefully remove the trim strips and just seal the water out with gobs of occu-pucky.
- "Cowl" drains plugged. The "cowl" being the section between the hood and the windshield, where the fresh air intake grill is. That area under the grill has a small drain opening at each end, near the hood hinge/spring assemblies left and right. The drains are at the weld flange on the body inside the fenders. You can maybe see them with a mirror through the door jams. The drain holes get plugged with leaves and junk. To clean the inner cowl area and drain holes, go up through the fresh air doors for driver and pass, with a vacuum and maybe build some special hoses & tools to get over the lip. Or remove the heater and left air box. If air conditioned- I don't know- never had one.
- If really bad, then the plugged cowl drains caused that inner cowl to rust-through into the cabin, so all the water goes on the rug.
- Others may offer their thoughts??? We'v had 9 74-76 Darts, and in Seattle, they ALL leaked to some degree.
