Blinker problem.

[Andrew XJ]

my blinkers have suddenly stopped blinking sometimes they work but only when the headlights are turned off but I Drive a lot at night really need to get them fixed any tips or suggestions I can use them as soon as possible.

That is a tough one. But I would check grounds on all the lights. That seems the best possibility. Many of them have common grounds. Reestablish them again or separate and ground

Whens the last time you checked the blinker fluid? ;)
