The problems started when we found out that my car had no dim lights even though the bulbs and fuses seemed to be perfectly fine, and so were my brights. So the mechanic somehow "jumped" my dim lights through my brights and managed to get both working. We discovered a few days ago that my passenger light was out, and upon looking at it found that the wiring shorted and actually melted parts of my headlight assembly. The lights on the driver side (dim and bright) both still work fine. From what I'm reading online it sounds like it could be an issue with a relay, but my knowledge of cars is extremely basic.
Could someone please tell me if this sounds like a relay or if it is more likely to be something else?
