I need to order a part for my 2007 HHR but I have no idea were I can find one

This is what I got off the sticker from in my car.

SN: C100345521
DESC: Center Stack Assembly
BSN: 0154779

 

I don't know what a "Center Stack" is, but none of the number sequences match GMs 8-digit numeric form.

When you find the actual part number or do some more searching this is one of the many(two) most mentioned sources:
gmpartsdirect.com

 

What part are you looking for? body.drivetrain, what?

 

That thing, the plastic cover that all the switches are attached to.

 

You could try somewhere like http://www.gmpartsdirect.com but for trim parts, you're more likely to only find them direct from GM or a used part on ebay or at a breaker's yard.

 

I've seen a few on Ebay recently.

 

Yea, ebay listing $55.00 shipped to your door:

Hope this Helps,
