Hi,

either the clock spiral spring broke or the wiring got cut.

you have to remove the steering wheel to access it:

NOTE Rotating the steering wheel so that the access holes on the backside of the steering wheel are at the 12 and 6 O'clock positions will allow tool access and reduce the potential of marring the steering column.

Hi,

if coil assembly needs to be replaced, here is how to install the new one and center it:

WARNING The SIR coil assembly wires must be kept tight with no slack while installing the SIR coil assembly. Failure to do so may cause wires to be kinked near the shaft lock area and cut when the steering wheel is turned.

Fig. Centering the coil assembly

  1. Pull the wire tight while positioning the SIR coil to the steering shaft.
  2. Align the opening in the coil with the horn tower and "locating bump" between the two tabs on the housing cover.
  3. Seat the coil assembly into the steering column. Attach the coil assembly retaining ring. Ensure the ring is firmly seated in the groove on the shaft.


WARNING Gently pull the lower coil assembly, turn signal and pivot and pulse wires t remove any wire kinks that may be inside the steering column assembly. Failure to do so may cause damage to the wire harness.
  1. Install the wiring protector.

is there a way i can clear the air bag light off of it so i can see my instument panel before replacing the clock spring if that is what it is?
Expert:  Eric replied 5 years ago.
Hi,

you can disconnect the battery for 10 minutes and then re-connect. this resets all the computers and erases codes. If the air bag light comes right back on, then it is indeed a hard fault that will require repair before the airbag light will turn off.
