EXTERIOR LIGHTING:HEADLIGHTS:SWITCH
ON PRIOR OCCASIONS, VEHICLE EXPERIENCED INTERMITTENT LOSS OF INTERIOR LIGHTS ON INSTRUMENT PANEL. RECENTLY,EXPERIENCED LOSS OF HEADLIGHTS ON 92 MERCURY GRAND MARQUIS DURING TRIP OVER THANKSGIVING HOLIDAY. CONSEQUENCES COULD HAVE BEEN FATAL HAD THE LIGHTS NOT CAME BACK ON AFTER I TURNED THE HEADLIGHTS OFF AND THEN BACK ON AGAIN. IN AN ATTEMPT TO REPLACE WHAT I THOUGHT WAS A FAULTY HEADLIGHT SWITCH, I DISCOVERED A WIRE HARNESS CONNECTOR TO THE HEADLIGHT SWITCH SHOWS INDICATION OF HIGH TEMPERATURES DUE TO BURNING AND MELTING. SIMILAR TO RECALL ON THE FORD CONTOUR. (SEE NHTSA CAMPAIGN ID NUMBER: 99V103000 ). I PLAN TO CONTACT FORD AND SEE IF THEY WILL REPLACE FOR FREE AND OR GIVE ME THE PART NUMBER OF THE HARNESS CONNECTOR PART SO THAT I MAY BE ABLE TO REPLACE. I PLAN ON KEEPING BOTH THE FAULTY CONNECTOR AND THE ORIGINAL SWITCH IN THE HOPE THAT IT WILL BE OF BENEFIT TO UNDERSTAND THE FAILURE MECHANISMS OF THE EXTERIOR HEADLIGHTS.

EXTERIOR LIGHTING:TAIL LIGHTS:SWITCH
WHILE DRIVING AT NIGHT, IT WAS NOTICED THAT THE INSTRUMENT PANEL LIGHTS, TAIL LIGHTS, AND PARKING LIGHTS WERE NOT LIT EVEN THOUGH THE HEADLIGHTS BRAKE LIGHTS AND TURN SIGNALS WERE WORKING PROPERLY. THE FUSE FOR THAT CIRCUIT WAS CHECKED AND IT WAS NOT BLOWN. THE DASHBOARD WAS DISASSEMBLED FOR REMOVAL OF THE HEADLIGHT SWITCH AND IT WAS REVEALED THAT THE WIRE TO THE TAIL LAMP/PARKING LAMP/INSTRUMENT PANEL HAD BECOME HOT ENOUGH TO MELT THE WIRE ITSELF. THE CONNECTORS FOR THE HEADLIGHT SWITCH ARE EN-BLOCK AND CONSIST OF 7 CONNECTORS IN ONE BLOCK AND 3 CONNECTORS IN A SEPARATE BLOCK. THE 7 CONNECTOR BLOCK HAD BURNT PLASTIC IN THE AREA OF THE TAIL LIGHT WIRE, AND THE 3 CONNECTOR BLOCK WAS WARPED FROM THE HEAT. THIS IS A 1992 MERCURY GRAND MARQUIS THAT WAS BUILT IN MAY OF 1991. REPAIRS ARE AWAITING SUITABLE REPLACEMENT PARTS.
