There is a fault with your electrics to the fan/switch. Get in an electrician to fix it.
------------------------------------------------------------
The switch is bad. Turn off the power to the fan in the main panel, turn off the breaker
that powers the fan. Usually if you remove the bottom cover of the fan you can see the switch. You can remove the switch and take it to a electrical supply store and they will match the switch. The wires should all be color coded so you should be able to put in back in and hook it up. Black to black, white to white.
That led is only showing that there is power to the switch and/or the light and fan fixture. You would have to check the power at the fixture to determine if it is actually in the switched feed or the fan/light assembly.
Yes. Even with no power to the light, there is still power to the switch. To power off the switch you usually need to open a circuit breaker.
Yes it is still on and using as much power as if it was on full
When a switch is closed the path through the circuit is continuous.
Unless you trapped a bumble bee in the switch, it shouldn't be making any sound. Sounds like a loose connection somewhere in the box where switch is located. Is there any flickering in light? That would be a clear indicator. There also could be a faulty switch where the internal contactors are chattering because of corrosion or misalignment of contacts. To check this out turn off the power at breaker and pull switch and wiring out of box and then turn on the power and see if it is anything obvious (The bumble bee flies out). If it is still buzzing and you can't see why then turn off power again and remove one lead from switch. Put a wire nut or tape on bare wire so you don't get shocked. Turn off power and see if buzzing still there. Repeat for all other wires until buzzing stops. If all wires are off switch and buzzing still happens, do the same on the other 3-way switch in the circuit.
Nope, it turns off when the water is boiled.
Make sure that there is power getting to the ac clutch when the switch is jumped. If the power is there then the clutch is bad and needs to be replaced.

Because the switch has a fault and needs replacing before you waste a whole lot of energy (which you pay for).

I would check power coming off of the switch; you will have to pull the switch out of the dash to check it and if there is power there, you will need to check the wire back to find the short.
Because a switch is a 'permanent' action. A relay only completes the circuit while there is power. If there is a fault in the circuit, a switch will still allow power through, whereas a relay will break the circuit.
The load will be zero after the switch is turned off. if power is still being drawn then the switch is quite likely faulty
Getting power to motor? if so could be a bad motor if not could be bad resistor pack or bad switch
You have a short in the cluster.
You can either go to switch or to light first. I wired house for my brother ran power supply from junction box then to each switch then to light. Passed inspection no problem
