I have a 1995 YJ Rio Grande. When I turn the headlights on, they stay on for 3-5 minuts then go out, yes, the markers all stay on. Then they will come back on after 10-30 seconds, then go off again after 30-45 seconds, then come back on in 10-30 and keep cycling this way. Toggling the headlight switch makes no difference, turn signals still work. What's going on? Bad relay? If so, where is it located? I don't have a decent wiring diagram...Haynes...so any help woulf be appreciated.
