I have a bad secondary fan motor on an 87 iroc 5.7 tpi. it tries to turn and just grinds anyway I am overheating in traffic. So I go to the local auto parts store to get a new one an the only one they sell is the primary fan motor. Its GM part # 22069066 with an 013 underneath the number. The parts guys at autozone and oreilly say they cant even order it. Any help would be appreciated.

 

Try Ebay or local Junkyards to see if you can find it. Those are usually good (and cheaper) sources to find parts that a bit harder to come by. Have you looked on craigslist?
