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.

Thank you!

Which fuse number/cavity and what size fuse?

I want to check as there are sometimes more circuits to a fuse than what is listed for it.



Customer: replied 8 months ago.
in the rear power distribution center fuses, the one in the trunk of the car, when I pull out the pink 30 amp number 5 fuse ,then the draw drops to 0.I looked at my car's book and is telling that this fuse goes to heated seat/steering column. I did disconnected all cables and plugs to the seats but no drop on that draw unless I am missing something. what do you think , Sr.?
Expert:  Joe replied 8 months ago.

Is your vehicle equipped with a heated steering wheel?

Are any of the steering wheel controls not working or acting unusual? As well as anything else on the column, horn, wipers, etc.
