Headlights problems of the 2005 Ford Five Hundred

Replaced low beam headlamp on driver side, noted electrical burn marks on one terminal. Replacement bulb did not work, had to wiggle to get it to work. Quit working daily without wiggling whole lighting socket , took apart noticed that the socket housing was brittle and cracked with burn mark on metal female lead. Two to three weeks later passenger low beam headlight would not work, wiggled passenger side light, came back on. Sometimes both light would go out at same time. Problem kept occurring through August. Found this has occurred on other Ford Five Hundreds due to sockets overheating. Checked passenger socket and compared to driver side and both sockets and light bulbs look identical in damage. Burned/melted plastic on bulb base and cracked burned sockets. Replaced both side bulbs and sockets last weekend, both lights worked for three days before apparently fused the socket with the bulb on the driver side. Guessing the passenger side will do the same within next month like it did before.

The headlight socket on both headlights are over heating and melting causing the bulb not to operate. I'm just nervous that this will cause a fire as all the parts are plastic. I also noted on line that it is a very real problem and I'm not the only one experiencing this.

The contact owns a 2005 Ford Five Hundred. The contact stated that the harness for the front passenger side headlight had to be replaced because it melted. An authorized dealer stated that the failure may have been caused by excess moisture, but the contact stated that the headlight became brittle and fractured. The dealer also stated that the top motor mount had worn. The contact felt that these were manufacturers defects. The failure mileage was 70,000 and the current mileage was 89,700.

My 2005 Ford 500 bought used September 2009 (around 53,000 miles current miles 55,432) has had a problem with the driver's low beam burning out. On the 3rd bulb replacement in less than a year the entire headlight socket crumbled in my hands. I had to replace the socket and rewire it to the wiring harness.
