[FC] Brake Light Question

[scwilson8126 at wowway.com]

Hello All; 



Last night I discovered that the brake lights are out on my Rampside but the running lights are fine. 



My first thought is to replace the brake light switch, but is there something else I can try first?  I'm assuming the ground is good since the rear lights come on when I turn them on. 

I do have a 3rd brake light in the back window which is also out. 



Thanks, 



Scott Wilson
