So I got blind spot mirror with puddle and turn signal, I already knew the blind spot wasn't going to work but I was hoping the puddle or the turn signal would and they didn't so I'm here hoping one of yall can help me with this

 

I can't say I have an answer for you, only a theory. On modern cars, I personally avoid these sorts of modification. But to each their own. . .

There's at least a chance that, in addition to installing the mirror and connecting to the harness, you'd also have to get into the vehicle computer and turn on the functionality. Just installing and connecting things often isn't the answer any more.

JMHO.

 

Yours may not be a kit mirror, but thought this might give you some clues on how you would go about hooking yours up.
