FOUND CONNECTOR ABOVE DOOR 3 LT SHORTED. *S/D* PIN 1 ON CONNECTOR D6535P SHORTED TO PIN 2. PIN 1 IS 115 VAC AND PIN 2 IS AC GROUND. THE SHORT DAMAGED BOTH THE PLUG & SOCKET CONNECTORS. WIRE WAS DAMAGED ON THE PLUG SIDE. EVIDENCE OF WATER ON THE CONNECTOR AND OTHER COMPONENTS MOUNTED ON THE OVERDOOR PANEL. POSSIBLE WATER DRIPPING ON THE CONNECTOR CAUSED THE SHORT.
