I have a cream puff of a 1994 f150 4x4 extended cab, I am the second owner. I noticed last week on my dash the brake light was on, but the brake l was not on, so I turned the ignition on and off and it went off. three weeks later, I got in the truck, once again, went to roll the window down, would not work, blinker would not work, but truck drove, the automatic transmission shifted stiffly. pulled over, turned ignition on and off and everything worked fine, drove smoothly home . I went back thru the previous owners meticulous records and noticed he had the ford dealership early on fix something on the ignition, problems with the key. Any ideas where to begin? Thank you Rick
