Is the power steering on a Saturn ion 3 fuse?

The Saturn Ion doesn't have a dedicated fuse specifically for the power steering *pump* itself. The power steering pump is generally powered directly from the battery through a relatively large wire, and relies on the power steering control module (if it has one; some models are simpler) for operation. However, there might be a fuse protecting the *power steering control module* or a related circuit.

To find the relevant fuse(s), you need to consult your Saturn Ion's owner's manual. It will have a fuse box diagram showing which fuses protect what circuits. Look for fuses related to power steering, the power steering control module (if applicable), or possibly even a general "powertrain" fuse that could affect it. A blown fuse in the power steering control module circuit, for instance, could prevent the pump from working.
