This is the genuine GM part I purchased: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1. I found some cheaper ones on other internet sites that may have worked but they either weren't genuine GM or didn't provide enough information to show that they were the right parts.

My thread is https://www.aveoforum.com/forum/f108...-issues-24336/ where I described some other issues I was having. Replacing this part solved all of them.
