Here's Your basic 09 mirror. From here you take a small (tiny) flat head screw driver and take off the face plate. There is just clips, no screws holding it in.
Once the mirror is off. You'll see the wires attached to the mirrors (if your mirrors come heated) if not they'll be no wires there.
This is the screw you need to loosen. This is what's holding the blinker on.
This is the harness for the lights. Just plug this out and your blinker will be disconnected from the mirror.
