This Bulletin is being revised to add additional symptoms and conditions. Please discard Corporate Bulletin Number 83-83-20 (Section 8 - Chassis/Body Electrical)

### Condition

Some customers may comment that the key warning chime continues to sound after the ignition key has been removed from the ignition lock cylinder. They may also comment that the automatic power door locks will not lock the doors when the key is removed from the ignition lock cylinder and the warning chime is sounding.

On Corvette models, some customers may comment that there is an intermittent operation of the passive keyless entry system, the steering column lock, or the retracting feature of the memory power seat option when exiting the vehicle.

### Cause

The actuator, located in the ignition lock cylinder, may be sticking after the key is removed.

### Correction

Remove the ignition lock cylinder for the instrument panel using the following procedures. Once removed from the vehicle, use the "Actuator Type Identification" and "Test Procedure" sections later in this bulletin to determine the correct repair procedure.

#### Figure 3 -- Lock Cylinder in Vertical Position for Actuator Testing

(1) | Actuator in the Up Position with the Key INSTALLED in the Lock Cylinder
(2) | Actuator in the Down Position with the Key REMOVED from the Lock Cylinder

#### Test Procedure

Early Design Actuator:

1. With the lock cylinder held vertically as shown in Figure 3, remove the key from the lock. When the key is removed, the actuator should drop down in the lock cylinder approximately 4-5 mm (3/16 in). Repeat this step several times.
2. If the EARLY design actuator in the lock cylinder does NOT drop down, replace the complete lock assembly.
3. If the EARLY design actuator in the lock cylinder DOES drop down, replace the actuator with the new design actuator P/N 12450483.

To replace the actuator, install the key in the lock and grasp the end of the actuator with a pair of small long nose (needle nose) pliers and pull firmly. With the key still in the lock, install the new actuator by aligning the actuator shaft with the opening in the lock cylinder and pushing the actuator into place. Verify the correct actuator operation by performing Step 1 again.

Important: After installing a new actuator, correct actuator operation must be confirmed.

#### Test Procedure

New Design Actuator:

1. With the lock cylinder held vertically as shown in Figure 3, remove the key from the lock. When the key is removed, the actuator should drop down in the lock cylinder approximately 4-5 mm (3/16 in). Repeat this step several times.
2. If the NEW design actuator in the lock cylinder does NOT drop down, replace the lock cylinder assembly.
