2009 M35 RWD HR engine.
I went into the M35 and started it up. It's being driven 2-3 days per week on average. No warning lights, no issues starting, no electronic issues ever until today. I started the car - started normally and 2 seconds later, the passenger window put itself all the way down. Neither the driver switch or passenger door switch will raise it back up. All other windows operate normally by door switched or driver's door. Sunroof, both front and rear eats, sun shade, and both mirrors all operate normally. The passenger window motor makes no noise so I reckon it blew, but why did it open itself before dying? It's a head scratcher. Any ideas?
Is there a way to manually raise it so I can unplug that motor and replace it with new?
