How to open window motor plastic housing?
 

I believe my driver's side window has stopped working due to a broken regulator gear. I've removed the whole motor assembly (see pic); however, I can't seem to pry open the damn housing--already broke one "leg" and small tab trying to pry it open (see pic). There are 2 youtube videos that make it seem very easy... What am I doing wrong?

Thanks,

Nevermind. I beat the other side with a brass tap and it popped open... Now to see if I can undo the damage I've done...
