# Rear Window Defogger On When the Ignition is Turned On

Subject: | Rear Window Defogger On when the Ignition is Turned On -- Replace the Alarm Assembly

Models: | 1995 Saturns built before and including VIN SZ158472 without electric locks, and VIN SZ160519 with electric locks.

### Condition:

On some vehicles, the rear window defogger may turn ON, without rear window defogger switch input, when the ignition is first turned ON. the rear window defogger telltale will also illuminate.

### Cause:

Certain variations and durations of voltage levels internal to the first design seat belt and ignition key alarm assembly (vehicles without electric locks) or multi-function alarm assembly (vehicles with electric locks), can cause the rear window defogger to turn ON without rear window defogger switch input. This could happen during each ignition cycle.

### Correction:

Replace the first design alarm assembly with a new second design alarm assembly, depending on the vehicle, according top the procedures in this bulletin.

### Procedures:

Notice: The operator is required to equalize and charge on his/her body by making good electrical contact with a metallic ground prior to handling the alarm assembly. These assemblies are considered electrostatic discharge sensitive devices. This procedure should be repeated occasionally during handling of the module and more frequently when the operator is required to change position such as walking, sitting down from a standing position, or sliding across a seat.

1. Remove the drivers side front floor console extension to expose the instrument panel junction block (IPJB).
2. Pull the lock tab on the bottom side of the IPJB (located underneath the alarm assembly), outward to release the alarm module.
3. Carefully pull out the alarm assembly.
4. Carefully plug the new alarm assembly into the IPJB until it locks into place.
5. Install the drivers side front floor console extension.
