MY headlights all of the sudden stopped working. The parklights work. The fuse is fine. The headlamps are fine. It must be in the wiring. Trying to locate the relay. Can you help?

Welcome to the forum, no relay, but, there is a circuit breaker in the headlamp switch, only for the headlamps. The other lites activated by the headlamp switch are fused circuit. Check the wiring circuit at the head lamp switch, red wire is hot all the time, remember I'm only talking the headlamp circuit. When you turn on the headlamps switch, lite green wire goes hot carries voltage to the dimmer.
