1994 MERCURY GRAND MARQUIS: DURING A DRIVE AT NIGHT, THE HEADLIGHTS BEGAN TO FILICKER AT FIRST (ALONG WITH INTERIOR PANEL LIGHTS); THIS WAS ONLY INTERMITTENT, AND COULD BE SOLVED WITH PRECISE PLACEMENT OF THE PULL SWITCH. WITHIN 10 DAYS, THE FILCKERING WAS UNCONTROLLABLE AND NO LONGER INTERMITTANT. I OPENED UP THE DASH-BOARD TO POTENTIALLY REMOVE THE SWITCH FOR REPLACEMENT. ONCE I HAD ACCESS, I TURNED ON THE LIGHTS AND BEGAN TO MANEUVER THE WIRING TO 4658078 ATTEMPT TO DUPLICATE THE PROBLEM AND STOP THE PROBLEM IN ORDER TO CHECK FOR A LOOSE CONNECTION. AS I WAS REACHIG AROUND THE WIRING, I FELT A VERY HOT WIRE; UPON INSPECTION, I DISCOVERED THAT THE WIRE IN QUESTION WAS BURNED UP TO 1/4 " PAST THE CONNECTOR (EXPOSING ALL OF THE WIRE FIBERS) AND THE CONNECTOR ITSELF AT THAT POINT WAS CHARRED, WARPED, AND BLISTERED. I HAVEN'T REPAIRED IT AT THIS TIME.*AK
