Easy job. Had problem with spatial relationships though, was looking at it upside down and thought it was the wrong one.

Kind of BS though that I would shut my door and the window just dropped down. Turns out the cord was binding on the spindel in two different places so it came off and would not be budged back in place. Luckily got one off ebay for under 30 shipped (used).

Replaced knock sensor too. Easy but your hand will be bloody. Another one of those things I don't want to do again.
