Approximately two weeks ago (10/2014) i noticed that the headlights on my 1999 ford f-150 were not working. a few times once i returned to home i noticed that when i shifted the truck into park, the headlights came on. it did not appear to matter if the high beam or low beam lights were activated. i started to inspect the headlight operation and noticed that when i tilted the steering wheel to it's lowest position, typically it's operating position, the headlights turned off. when i tilted the wheel up slightly to the next position, the headlights would come on. today, 10/19/2014 i removed the trim around the steering column and noticed that there are two wires that have broken and separated from the wiring harnesses that attach to the turn signal assembly and several contacts that are loose in the upper harness. i have taken photos and a video showing the parts that are loose and or broken. because these broken wires and contacts are loose and affect the operation of the headlights, i am concerned about the risk of a short or sparks that they could create and without fully operational ...

The windshield leaks on this model style and the water runs down to the gem module and fuse box causing the gem module to short out and the electronics do what ever they want to. the truck will start on its own even if off or running and driving with the starter engaging. windows roll down the alarm activates radio comes on all the electronics come on at there own even when parked with the engine off and the key removed. this is a very common problem from my research to tens of thousands of these trucks. this is very dangerous due to the car can even engage the transmission as well as it can cut off while driving as it has with myself. this part is very expensive and the leak is very common. *tr

The engine surges or quits as i am driving. this happens every 8 to 10 miles. i can be going 75 mph on the freeway when it quits and i have to shut off the ignition to restart it. this is at least the ninth time this truck has done this since it was new. i think you can imagine what it's like to be going 75 miles per hour and your engine quits and you are left with no power steering, or brakes. this will be the ninth coil i have replaced on this motor. ford is completely aware that there has been a problem for years with this size motor. i can't believe an engine that shuts off at 75 miles per hour has not been considered a safety concern before. *tr
