This PI was superseded to update models and keywords. Please discard PIC3385B.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

### Condition/Concern:

Park Light fuse is blown

### Recommendation/Instructions:

A short to ground (STG) in Circuit 8 (output dimmer circuit) can cause the Park Light fuse to blow.

Document ID # 1381132, (Malibu)

Document ID # 1527768, (Cobalt/Pursuit)

Document ID # 1471242, (G6)

These document numbers will show that Circuit #9 (brown) goes to the BCM and is converted to Pulse Width modulation for the output on the illumination circuits (#8 grey wire). It is recommended that you check for a short to ground on the #8 (grey) circuits in the doors, around center console, and around/or near the drivers front seat track. On the Chevrolet Cobalt SS, check for a short to ground on the left side upper dash pad, as the wiring headed to the boost gauge may be pinched.

Note: DO NOT replace the BCM for the park lamp fuse blowing as it WILL NOT repair the vehicle.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
