i have a 2000 ford f250. when i hit the blinker left or right the third brake light and both blinker will flash. the license plate lights don't work and the reverse lights dont work all the bulbs are good. the daytime running lights and brake lights work. i checked fuse. all of the lights work in the front as they should. the 4 ways work as they should and the third brake light does not blink when 4 ways ar on i looked for ground problems and chafed wires did not find any did not look behind fuel tank because its 1/2 full and haven't wanted to drop it.
thanks for the help.
