2003mnss

Front diff good?

I'm thinking it has to be a wire tried combination switch, blinkers relay, bulbs etc but the weird part is shouldn't it atleast light the right blinkers on my cluster? And thanks for moving it sorry for putting it in the wrong section

So I picked up a 2003 ss today and noticed after I brought it home already go figure that my right side turn signal is inoperable front rear and mirror doesn't light up on dash neither and my right rear tailor light don't work neither. Anyone have any ideas where I should even begin to look on this one?
