Inside fan Part number???

I have searched the forum and figured out what my problem is, but I can not find the right part anywhere. I am looking for the blower motor fan relay/resistor. I bought one from NAPA and it was the wrong one.
Here is a picture of the one I bought.

It is the wrong one. I need the one with 3 connections not seven. Any help in finding where I can buy this part would be great. Also any part numbers for it too.

Thanks in advance.

Welcome to AF.

Your best bet on finding the right parts is to have your GM dealer decode you VIN no.
Works 99.9% of the time.
Good Luck

If you have the automatic ac is the relay is different get from a dealer as MT-2500 said.

I would try talking the old one an new back where you bought. This way you may get your money back or the proper part. They normally don't refund on electrical items but should in this case. Even if you buy from a dealer don't waste your money.
