The code they're getting indicates that the circuit is open on the driver's side. They say it's the clock spring because that's where the wiring flexes the most and therefore where it's most likely to break. You could have a connector loose under the driver's seat, poor contact between the clock spring and the wiring harness that plugs into it, or a broken wire elsewhere. Some people swear you should put dielectric grease on the contacts of the clock spring, others say you should never. But I think the majority have cleared the code by greasing the thing moderately -- not enough to short between contacts.
