    97 FLD. I have tails and markers but no turn signals or hazards on trailer. They work fine on the tractor. How do I troubleshoot. Thanks in advance.

    Check your prongs in the trailer connection box.

    Just use a screw driver (flat head) or a pocket knife to spread the prongs apart a little.

    Often the prongs will lose connection by getting crimped together at the separation slit.

    On drivers.side firewall under hood, there are separate fuses and circuit breakers for trailer lights. Your tractor lights will work, yet trailer may not. Check those first.
