Tail Light Newbie Problem Options

[passngo]

Hello, I need your help!

I have 05 corolla and driver side stop light does NOT work, but tail light works.

I have done basics, meaning checked the fusebox under the coin holder (stop 15) was good, and also replaced the 3157 light.

But it still does NOT work! Passenger side works and and tail light works but again stop light does not.

Can anyone give me some advise PLEASE!!!

I just don't want to give any reason to get pull over by cops (IMG:style_emoticons/default/grin.gif)

Thank you for your time to read my problem!
