I drive a 2000 F150 XLT, out of the blues the driver rear break and turn signal stop working. I replaced the bulb and flasher without any luck. traced the the wiring back to the turn signal switch on the steering column and find out that the output wire going to the driver side turn signal has no power going out. I replaced the harness going to the turn signal switch and did not fixed my problem. Does anybody have a clue of what might be my problem? Thanks to all of you for the help.
