Santos Posted December 14, 2023 Share Posted December 14, 2023 Hi i currently have no turn signals or hazards. I purchased a relay from Napa and also installed another Mack’s turn signal switch and no luck. Anywhere else I should look at? Thanks.

You probably have all LED lights and the one incandescent bulb you have on the turn signals failed. Probably the dash indicator bulbs. There's a special turn signal flasher for LEDs that has a grounding wire coming out that you're supposed to attach to a good ground. LEDs don't draw enough power to trip the old style turn signal flashers, so they've made that special electronic one with the grounding wire to overcome this issue. 1 Quote Link to comment Share on other sites More sharing options...
