I wanted to quickly warn members not to order the part yourself from gm parts direct dot com. Firstly, it is a nonreturnable item. I ordered it (my dealer won't fix what isn't broken) and received the part with NO tabs and there is no way to return the part!

Here's the worst part of the story. I checked the car again and I actually have the plastic pieces. Yup, I originally checked at night, even with the car port light on it seemed they weren't there. I guess I ordered a part I didn't need.

It gets better, they still haven't charged my credit card, even though I've received the part and they've sent an invoice marked as "paid". I think I may have lucked off on this one. I might be inclined to tell the company they screwed up under normal circumstances, but, as it is, they cheated me by sending an obsolete part that I couldn't return. I think we're even.

Just because I'm lucky doesn't mean you will be! Don't order the part yourself, fight your dealer instead if need be.
