I need help findingg an issue

My rear window switch is no longer lighting up. What fuse is used for that button? Also at the same time my switch backs stopped working also

 

I don't understand what you are saying. Do you mean your back window on your crewmax isn't going up? What are "switch backs?"

 

So I wired up a led light bar in my 16 sr5 crew max and tapped into the switched wire that lights up the buttons( on my truck it happens to be a light green wire) on the driver left side (rear window switch, etc) and I'm pretty sure I blew the fuse to it. Now that button will not illuminate.s switchbacks are turn signals that will light up white but when used they turn amber, and after they go back to white light. After everything my lights stay amber at all times and my buttons will not light up anymore. I did you the ground next to the hood latch. What does that go to? I'm pretty sure whatever that goes too is what I blew the fuse too.

 

The wire only lights up my button, I do have the bar with a relay directly to my battery. So the way I have it wired up is so the actual switch only carries ground.so if my memory serves right 86 and 87 are bridged and have 12vts, 30 leads to the power wire on the bar and 85 is the ground that leads into the cab. My switch has 4 wires, 2 for the relay and the other 2 I tapped into the the rear window button wire so my button could light up
