Hi, I have a 1999 Jeep Grand Cherokee Limited with a 4.7l powertech engine.my tail lights and park lights do not operate. But the brake lights and all 4 turn signals work. the park light circuit fuse under the dash is good. and i didnt check the bulbs yet but I dont see how all 6 bulbs are burned out when they all worked this morning. I do have halo projector headlamps and aftermarket tail lights. the leds and the halos on the headlamps ARE wired to the park lights. I dont know if that would cause this or not? Please help me I already got pulled over at work because of it (pizza delivery).
