maybe you have already done this, but remember that many laptops require that you remove the battery for about 30 sec. as well as disconnect the AC power to reset them.
Always try this when everything seems completely dead.

The battery in the unit may need to be replaced. Usually it is a 12Volt 7Ah high discharge, Sealed Lead Acid Battery.

They life span is around 2-5 Years.

Take care!

1. If equipped, disable the SIR system. Disconnect the negative battery cable.
   
2. Remove the upper steering column cover.
   
3. Remove the lower steering column cover screws and lower the steering column cover.
   
4. Remove the 2 switch mounting screws and remove the switch.
   
5. Detach all wire connectors from the combination switch. Push locking tabs to remove the wires.
   

To install:

1. Attach all wire connectors to the combination switch.
   
2. Install the combination switch to the column with the 2 attaching screws.
   
3. Install the lower steering column cover screws and lower steering column cover.
   
4. Install the upper steering column cover and attaching screws.
   
5. Connect the negative battery cable.
   
6. Enable the SIR system, if equipped.
   

Align the steering wheel so the tires are straight and then remove the ignition key from the Saturn.

2 Remove the lower right side console trim panel to reveal the fuse box panel. The trim panel simply pulls off with a sharp tug. Locate the supplemental inflatable restraint (SIR, or air bag) fuse and then remove it with the fuse puller. Refer to the repair manual for the fuse schematics, if necessary.

3 Open the hood and then disconnect the negative battery terminal from the battery, using a ratchet and socket. Isolate the cable so the terminal does not come into contact with the battery post during the repair.

4 Loosen the four SIR retaining fasteners located behind the air bag module at the rear of the steering wheel using a ratchet and socket.

5 Remove the inflator module away from the steering wheel carefully. Disconnect the connector position assurance (CPA) device from the module. Disconnect the yellow SIR connector at the base of the steering column. Unplug the wire harness from the module and then place the module in a safe place away from your work space with the trim panel facing up.

6 Pry off the upper instrument panel retaining caps with a slotted screwdriver and then remove the trim panel retaining screws. Lift the trim panel upward to disengage the rear retaining clips. Disengage the front trim panel clips by lifting upward at each front corner. Remove the trim panel from the vehicle.

7 Disconnect the CPA device from the passenger-side air bag module and then disconnect the yellow SIR wire from the wire harness pigtail located under the passenger-side dashboard.

8 Disconnect the wire harnesses for the horn and cruise control (if equipped) from the base of the steering wheel. Remove the retaining clip at the center of the steering wheel (if equipped) and then remove the mounting nut beneath it. Pay attention to the alignment of the steering wheel locating notch for reassembly.

9 Apply the steering wheel puller to the steering wheel and tighten the center nut of the puller to draw the steering wheel off the column slowly. Tape the SIR coil into position to prevent accidental coil damage from occurring.

10 Remove the two retaining screws and then the upper steering column cover. Pry off the ignition lock bezel and then remove the two lower retaining screws and the lower steering column cover.

11 Remove the SIR coil from the combination module. Disconnect the CPA device and the wires from the combination switch. Remove the combination switch retaining bolts and then remove the switch from the steering column assembly. If necessary, remove the instrument panel trim covers and center console trim to access the switch fasteners for removal.

12 Disconnect the ignition switch connector and then remove the two ignition switch retaining screws. Disconnect the switch from the ignition module and then remove it from the steering column.

13 Reverse the procedure to reinstall the new replacement ignition switch.
