What is this part called?

[PhillyPhreak]

I had my front windows tinted today to match the rears. The installer melted the drivers side front window (corner cap?)cap thats on the outside toward the rear of the window. This probably wouldn't bother many people but it's driving me nuts! Is their a part number or name of it that I can go to my local dealer and ask for? I'm only asking becuase when I went to order mirror caps the parts department couldn't find it and told me I had to order a whole mirror to change from chrome to black.
