2014 GMC Terrain lighting problems

Headlights- melted plug causing fire damage on both headlights, replaced with new headlights and bulbs as well as a new wire harness plug. Was driving smelt smoke/wires burning. Wipers- stop preforming during rain storm Southeastern NC on hwy 701 south on 3-24-22. And still does not work. Maybe be associated with older model terrain recall. Same happen to this model.

Tl* the contact owns a 2014 GMC terrain. While driving at night, the low beam headlamps failed to project far or wide enough ahead to drive safely. The contact was informed that the headlamps performed as intended. The headlamp bulbs were replaced with brighter bulbs; however, the replacement failed to remedy the issue. The manufacturer was notified. The approximate failure mileage was 42,678.
