I have a 1990 Jeep wrangler I am having a problem with the headlights, when I turn on my parking lights my headlights come on with them. I have no high beams low only. I replaced the park light and headlight switch that is located on the dash, but still having the same problem. Someone told me to replace the headlight relay. Does anyone know where the Headlight Relay is located on the jeep? Or what do you think the problem is with it. Thanks
No relays whatsoever. The factory switch has a built in failsafe incase there is excessive current- it flicks the lights off momentarily until the unit can cool back down and re-power the headlamps. Replacing the switch is always a good idea, because they can build up resistance overtime. Consider doing the Headlight Relay Upgrade to send direct voltage to your lamps (you lose a volt or two (or around 100-200 lumens or so) using the factory wiring) and get better light output.
I replaced the headlight switch already that's on the dash. I will check the ground next if that's not the problem should I change switch on column this is the only thing holding me up from putting this on the road.
