E39 third brake light problem

[affan66]

Folks,my third brake light is not working. I believe it is a wiring problem. The bulb looks fine.Tried looking for the wiring diagram but I have trouble finding the right info. This is the source that I use: http://spaghetticoder.org/bmw/wds/e39new/

Few months ago, meter panel shown me a 'ting' sound and a problem with the rear light indicated.
Its the 3rd brake light and I got it solved for rm25, the whole 3rd brake light socket.

same here... the ting and rear light came up, right side. The 3rd brake light is connected to the right brake light circuit. Today shops close. grrrr. thanks isaacvky
