What was found
LEFT FRONT AND RIGHT WINDSHIELD HEAT WILL NOT SHUT OFF WHEN DESELECTED. FOUND LEFT FRONT WINDSHIELD HEAT CONTROL RELAY AND SOCKET OVERHEATED. THE WIRES CONNECTED TO CONTACTS A1, A2, B1 AND B2 WERE BROWN FROM OVERHEATING. THE PLASTIC ON THE SOCKET HAD STARTED TO DEFORM FROM OVERHEATING, RELAY AND SOCKET WERE MELTED TOGETHER SO WE COULD NOT GET THEM APART. REPLACED THE RELAY SOCKET AND ASSOCIATED WIRING. FEEL THAT THE WIRING, THE SOCKET AND RELAY ARE NOT MADE OF A HEAVY ENOUGH MATERIAL TO HANDLE THE LOADS THAT ARE CARRIED. RELAY PN GAR835NL1, SOCKET PN GAS5825BA1.
