IF you, or anyone, decides to go with new OEM, I picked up one for my 13 LX from Serra Toyota during the 25% black friday sale for just under $800. I have the original if anyone needs to replace one that is beyond repair. Left side and everything worked as it should when removed by the body shop at local Toyota dealer. Not free but still cheap.
I was told by the body shop that they need to be calibrated after installation. Can anyone confirm that? If so, it definitely adds to the cost of replacing them.
