Put on light switch all lights come on..but push on brake, no brake lights. No turn signals and no hazards.. replaced fuses put in new signal harness replaced bulbs (twice). We are thinking a short in this truck also. But not sure where to start or check something else first. thanks

Hello,

This is common when the contracts in the hazard switch become dirty. I would try aggressively cycling the hazard switch back and forth to help clean the contacts. Let me know if that helps.

Sorry, just remembered we replaced the whole turn signal harness, which included a new hazard switch.

Okay, here is a guide to help you test the connection and for power and the brake light wiring diagrams so you can see how it works. Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.
