The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
When servicing the headlamp ballast on a 2005 Corvette built between August and September of 2005, it is important to inspect the ballast prior to ordering and replacing with a new part. Some of these 2005 vehicles were built with a 2006 ballast. Ordering the 2005 ballast based on the parts catalog may not offer the correct ballast to fit the vehicles application. Please refer to the inspection below to order the correct ballast.
Recommendation/Instructions:
Remove the ballast cover. While the ballast is secured to the cover, inspect the corners of the ballast case. If there are 4 small screws, one is each corner of the ballast (these four screws hold the case halves of the ballast together), the ballast is for a 2006 and will require part number 89025794 to repair. If there are no visible screws in each corner of the ballast while the ballast is secured to the cover, this is a 2005 ballast and part number 12335922 will be needed.
2005 Part Number, 12335922
2006 Part Number, 89025794
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.
