Sankekur said:Neither the plug nor the socket need to signs of melting for it to be an ground issue, if left long enough it will melt though. The first thing that happens is more oxidation on the contacts due to it being hotter. Re-seating the connector can temporarily solve this it will remove some of the oxidation and again allow for proper contact.
Though the best option is to solve the problem which is contact resistance that is not low enough, the easiest way of doing this it to simply add another connector in parallel to lower the overall resistance, this is how I did it on my car:
The one end is connected with a spade connector to the ground on the bulb cluster, the other is tapped into the brown wire on the harness.

This was exactly what I was gonna tell u to do...
