2001 blazer 4x4 4dr. The rt.side tail/running light is out. Fuses ok, no power to brown-white wire in right rear(brown from rt.side connector to socket). Traced wire overhead to left side jack storage area. No power there either. Power through the fuse box under hood with headlight switch on. Does anyone know of a likely problem area, or where the wires run from the left rear to the front and if there is a connector along the way? All other lights work. Your help is greatly appreciated.
