I got no running lights on my 2013 gmc sierra 1500 but I still have every other light, does anyone know what could cause this problem. I had checked all the fuses and there good, took a test light and I have no power running to the rt park and Lt park, with the switch turned on I have power the the 2drl fuses under the hood,changed the junction box in the back attached to the frame and changed the switch in the cab out... I ran out of ideals on what it could be, I got Recon led tail lights
