Hi, Looking for help. 2017 Mazda CX-5, my right stop light does not work. I started obviously with replacing the bulb but it didn't help. Fuse checked but there is just one fuse for all three stop lights. Cables look ok. Any hints where to look further?

Thanks a lot.

Glad to hear you solved the issue!
