Chevy 2500 HD Brake lights not working


Asked by Oct 24, 2012 at 11:26 PM

Question type: Maintenance & Repair

The 3rd brake light works which leads me to assume that the switch on the pedal itself is working. The fuse for the stop/haz is good and the hazards work

1 Answer


The tail lights and turn signals both work as well. I have also removed the connector from the light switch module and jumped the 12V feed over to the brown wire which feeds the brake lights and they come on. The schematic in my Haynes manual indicates that there is something on the direction connector that has an impact on the stop light switch. How does the turn signal switch affect the brake circuit? Any ideas would be appreciated
