In my kitchen I have two 3-way switches controlling the ceiling fan and light. The two controlling switches are on opposite sides of the room, but what I'd like to do is split one of the two switches apart, adding a dedicated fan control, then tie off the fan portion of the other 3-way switch so it doesn't affect the fan at all.
The end result would be two 3-way switches for the ceiling light only, and a new switch just for the fan.
The problem is I can't identify the wires to control the light and fan individually. I've opened the fan/light fixture also, but there only appears to be one hot wire coming in from the ceiling (nutting together with what I assume are individual hot wires for the fan and light). Below are photos from the three areas:
