I have an Infiniti G37S 2009. According to the VIN it was build before November 2009. The window motor for the back window doesn't work anymore. The replacement part seems to be 80731-JK60C. It's a $250+ part before taxes. That's pretty expensive for a simple motor. I see motors for other models that are like ~$40 but I am not sure they will work. The link below does list "G37 2009-2013" but would this motor really work?

Looks like it should. At worst, you'll be able to compare them when you pull yours, and it's not expensive - you can return it if it's not right!
