So, the wife backed out of the garage and busted the glass on the passenger side mirror for our 2007 Jeep Liberty. I'd rather just buy the replacement part online than pay double to have someone else do it...I understand already that generally the entire fixture is replaced when this happens (replacement glass tends to fall out, and I'm not going to go the cheap route with 'plastic' mirrors).

When I'm researching the parts online, I find two models that would possibly be what I'm looking for...one is a power mirror (which I have), and one is a heated power mirror (not sure if I have or not). The manual says that if the heated mirror is on the car, it heats automatically, so there wouldn't be a button to turn on or off, etc.

I can't find anything that definitively lists the model part for me to look up to match exactly, does anyone have any suggestions? If it helps, it's a 6 cylinder 4 door 2 wheel drive sport model.
