Hot Door/Water Leaks on '76 450 SLC

I have two separate problems with my 1976 450 SLC. 1. The passenger side door on my 1976 450 SLC gets very hot to the touch, especially in two spots; near the door handle and near the arm rest in the middle of the door. Is this a symptom of an electrical problem? All electric devices (windows, etc.) work fine. Should I keep a fire extiguisher handy?

2. Whenever it rains heavily, water streams/drips from the firewall/dash to my right foot, near the accelerator. Please don't tell me to divert the water to the passenger door and then I'll solve both problems. My wife already suggested this. T hanks!
