I have a 83 F-250 4x4 V-6 4 speed, her name is Ruth Ann, I have replaced a bunch of things on her and she is running well other wise except for the high beams. They will be on for about 5 minutes and then go out or blink. Any idea's would be very helpful.
I assume you are going to change the light switch in the dash? If so, check the wiring plug to the switch, they are known to overheat and melt. I think you also meant you have a inline 300 six, not a v6 correct?
