1997 6.5 Suburban with no brake lights
Hi, all. The brake lights on my '97 stopped working, but all the other lights work. Before I condemn the switch at the brake pedal, I'd like to check for power out of it at the relay terminals. There's no brake relay in the fuse/relay box under the hood (driver's side), and no female terminals in it to receive a relay anyway, even though the cover diagram says it should be there. Does anyone know where the brake light relay is located? Thanks in advance.
