Darren Life Posted October 10, 2020 Posted October 10, 2020 2007 GMC Sierra Classic: today my turn signals stopped working in both directions but my hazard lights do work. I have checked all fuses, looking for advice on what to check next
davester Posted October 10, 2020 Posted October 10, 2020 (edited) perhaps the flasher module has failed. I believe they have separate ones for the blinkers and hazards. you can swap them to test if it's the problem.. Edited October 10, 2020 by davester
