I did this fix today and thought I would pass some info along to the forum. I needed the FSU ASAP because my wife and kids don't care to ride around with no A/C or heat. (My blower quit completely) I called NAPA to see if they could get the part because ordering online was of course going to take a few days. They indeed were able to get it, quickly. I called at 9am and they had it by 11:30. The part came from a company called Altrom. I asked the Napa guy how they compare to OEM parts. He informed me that Altrom doesn't manufacture anything. Instead they buy overstocked parts from other suppliers and repackage it in there boxes. He said the part I get could be from various different manufacturers. Turns out the one I got is a Behr. I followed one of the DIY's on here and the blower now works perfect.
Thanks for the DIY info.
