Great as usual
This was the exact part that I needed. Even though I couldnt find the part number on the old part. I just trusted that this would fit because this website said it would and they have never steered me wrong yet. I love the videos that they have on this website and I tell all of my friends. This is my go-to place for auto parts.

It works!
The resistor was going bad and I was losing speeds on my AC. Replaced with this part and all is well. Feels like the blower moves more air then before I was losing speeds as well.
