Top advice, thank you I may have to put a Multi meter on my Christmas list. I'll clean or replace the connectors in this light cluster first and hopefully it solves the problem.The grease (dielectric grease, not chassis grease) is there to stop moisture entering the plug connections and causing corrosion. That faulty connector you have, has been heated by a corroded electrical connection. They can get hot enough to melt plastic. You may still have another faulty connection somewhere. Remember to check all individual electrical connections for tightness. Use a multimeter to check for any electrical resistance across the connections. There should be none. To analyze electrical circuits on a modern computer controlled car, a circuit diagram is a big help. There maybe all sorts of obscure connections. Best of luck, these types of problems can give you a headache.The plug connecting the offside headlight is filled with grease, do you think this helps?
