Anybody ever have an issue with brake lights on 2007 suburban. Right brake light out, aside from tracing wire, everything checks out. Bulb good, fuses good. Anybody know if brake switch sends separate signal for left and right? Any help would be appreciated.

Same signal from the same brake switch for all of it.

Next step if it were me: Use a meter to see if brake light power is getting to the contact in the socket.
