AutoZone, NAPA, Advance Auto etc CANNOT test a modulated alternator, regardless of what they say.

You will probably need a NEW alternator. Do not buy an aftermarket reman. or rebuilt. New GM only! GM part number 92191127. Amazon and Rockauto have them in stock for $200 which is half of what most dealers will charge.
