Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.
There is no component called the power steering column, there is a power steering rack, power steering pump and then there is the steering column, I need to know to which you are referring.
My guess is the column, for this you have simply found a fuse that provides power to circuits, now it is a matter of finding what device/circuit the problem is on, for this you must isolate each circuit and I use a test light to check draw, when you can disconnected/isolated the problem circuit the draw will go way down to a dim light (unless a door is open, light on, etc .... so you must make sure these are out of the equation for testing). Once the light dims or using an analog meter you find the circuit that is the problem you can then trace the wiring for a short, relay, or the controlled device itself.
