The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Park Light fuse is open
Recommendation/Instructions:
A short to ground (STG) in Circuit 8 (output dimmer circuit) can cause the Park Light fuse to blow.
The circuit #9 (brown/park lamps fuse) wire 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. The BCM doesn't circuit protect the illumination circuit (#8) and will cause the park light fuse to blow if shorted.
Note: 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.
Important: 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.
