The blinkers and hazards where working, sometimes. Now not at all. 2000chevy HD3500

All bulbs are good, replaced flasher. Replaced blinker switch ($150.00). Replaced stop/hazard relay. Checked ground to frame coming out of wiring harness towards back. Still no worky!

With hazards on. Push brake, hazards come on in dash and in front. Dose not blink. Let brake lever up they go off.

Hi whirlwind, Welcome to 2carpros.

Test the turn and hazard fuses if okay, you have replaced the flasher already-Your probable causes here could be the body junction block on left side of dash or the turn and hazard switch-both circuits goes through this switch. Also you have many fuses that run the system here is a wiring diagram that show how the system works and which fuses to check I have also included a guide on how to check the power and grounds let me know what you find.
