I need to replace a front door on my 2010 rx350. The junkyard interchange is for 10 and 11 models only, however Lexus lists the door shell only interchanging between 10 and 15. So the door itself is the same for a models, but something else is different limiting the interchange. Does anybody know what that is?

 

Probably the wiring to the doors.

 

^^ Agreed.
