Any time a connector overheats, the plastic housing begins to warp and the issue has a tendency to snowball; the contacts loosen or come to be corroded or contaminated, increasing resistance that generates even more heat and promotes corrosion that boosts resistance much more.
This normally comes about with more mature/significantly less-widespread motor vehicles or if the maker not makes vehicles. And selected repairs don’t apply to each make & design.
