I am having a weird issue with my rear tail lights. They work for stopping, and turn signal but only come on steady for 4 way flashing. Everything worked fine until now (not sure when it happened, recently or why). The fronts work correctly when I turn the 4 way flasher on and the rears only come on and steady. Go out when I turn the 4 way flasher off. I am running digitail LEDs for the front and rear. I also have LED flashers installed. just wondering if I have a bad 4 way switch (in the column, Ididit column). Any help would be appreciated!
