90 gmc pickup fourway flashers

Blade Slinger

Turned them on and now no matter what I do cant stop them... battery cut off being applied now. backed screw out and put back like it was to no avail... blink blink. Im ready now to rip into steering column to see how this marvel works.

any ideas?

I imagine you need replace the flasher module....overrime they wear out and will get stuck in one of the two positions....you might spraying it with some PB blaster and seeing if that fixes it....honestly though they are pretty cheap to replace if that does not work.
