One of the biggest recommendations I can give... Only use GM/AC Delco ELECTRICAL Parts.

Take that as you wish.. but be warned... more than half of the issues I see are Directly related to the aftermarket part used. I've fixed countless vehicles with problems that lead back to those non-oem parts. That's why I suggested getting the oem p/n and searching it online new. You usually get pretty close to cost on items just by looking for them on Google.
