Rear running lights... help!!
 

Ok, I have an 85 maxima. Having issues with the tail lights. When turning on the lights, front lights work, turn signals front and back work, break lights work, but the rear running lights do not. Have checked and changed bulbs, went through all fuses under the dash, and swapped around relays for like ones that worked on other components that i know work. I'm running out of ideas here.... HELP!!!
