I need to replace my front driver side window regulator and motor, but am having a hard time finding the right one. I'm learning quite a bit by trying to replace this. My 2012 RAV is Canada built - as far as parts, do I need USA built parts, or Japan built parts? I've been told it makes a difference as to which one I get. I have found several Japan built, but don't want to buy it without knowing if it will work. Sure, I could return it if it doesn't work. But, history has proven that it would actually sit in my garage and never get returned. Thanks!
