3rd Brake Light Trouble
My 3rd Brake light is not working on 2009 CLS 550. Pulled everything apart IAW all the posts provided on this form (thanks) and removed light. Tested light with 12 volts directly from battery and it works. Reinstalled everything and chased wiring to see if I had a broken wire. Nothing found. Any advise on where to go next?

211 info should be same for 219. Pull rear SAM (fuse panel) located behind left trunk panel check connector 21, pin 22 on reverse side - brake pedal depressed 12V.
