    turn signal's reply go bad lot time when it old. My 79 f150 have those it dead and replace 2 times.


    Your truck sound fuse is blew it or not ground right it.


    for turn signal reply you should see that silver circle which look bowl but it is metal but most it could be metal or plastic. [​IMG]

    Mill's on the right track with the flasher....

    Since you mentioned that the turn/brake light goes out when you have the brake and turns on at the same time, there's a good chance you have a defective turn flasher. It's located in the fuse panel and should look just like the one in Mill's pic (bottom right corner).

    this wasnt the prob. i replaced the flasher w/ a new one and they worked. then i tried to pull out of autozone parking lot and no signals again. plugged in the old flasher and it worked again, for a minute. wiresinto the fuse block are good. what about the ground? where does it connect to frame?

    I think there are ground wires in the back near the tail lights that ground from the harness to the body or the frame.

    Does it only affect one side of the turns, or will it do it on BOTH sides?

    If it's both sides and the flasher didn't solve the issue then the turn signal switch itself is probably defective. It's the only other thing that will affect BOTH sides while the brakes lights are illuminated. Not at all uncommon for them to wear out on an old truck.

    The next time they don't work, try wiggling the turn lever slightly. Sometimes they will magically begin to work again.
