89 e350 brake light issue

Hi all i'm working on my moms 89 e350 motor home, both turn signals work so I know the bulb is good, but only the left brake light works, tried a new brake light switch with no difference, I'm not familiar with how the system works, but could someone point me in the right direction? thanks all

I would start by inspecting the bulb socket for the side that does not work. I have found that the contacts in them are not always reliable. You can check voltage with a meter to verify it is reaching the socket.
