cut the wire's??? why?? 2 wire's are attached to the actual mirror by spade connector's.
The mirror itself is held in place by an X shaped piece. I bought one year's ago.............weird name, I can't remember right now.
Get your fingertips around the edge of the mirror itself and pull straight out. Pull the 2 wires off of their spade terminals. That's it.
The wires on the back of the mirror are for heat only.
What tells them to come on?Get one from a JY and practice on it. You may have a broken piece (pc?) in the mechinism. If so, get the guts from the JY one and replace it. You can take the black motor assembly apart to put your good motors in it so that you do not have to splice the wires. Be carefull, it tends to fall apart after you remove the screws, and the parts have to go back in the same way they came out.
The mirror heat comes on automatically.
