In my bedroom , I have 3 switches, one for the bedroom lights, one for fan speed, and one for the fan. How do I wire them just for the fan and the bedroom lights?

Little difficult since we have no idea how it is now wired. Are there 3 power in wires or only 2? Turn off the power to the switches. The simplest way is to keep the hot on the lights, run a jumper over to the fan switch from the light hot feed. All whites stay. Disconnect the hot for the fan switch and the old fan hot and put wire nuts on those wires separately.
