works perfectly fine, the exact fit to your car, if you own a GM vehicle (I own a 2018 Malibu) make sure you special order whatever part you need if not you’ll end up on a hunt like I did. Anyways, works as intended but the replacement process was terrible, you need all kinds of pliers and protection, not worth. Not giving my money to a scumbag mechanic though so here we are.
