Electrical problem
1996 Ford Station Wagon 6 cyl Front Wheel Drive Automatic 172000 miles

We have a Ford Taurus wagon, when the car is in park or neutral everything is fine, when you put the car in a gear (reverse or drive) everything stops working, i mean the car still runs and drives however you have no power steering, no electric windows, no radio ect.. i am assuming that when the car is put into a drive gear it is pinching some wire but i dont understand what that has to do with the power steering.

Help
