I purchased these for a project vehicle and then decided to scratch the project all together.
I believe that they are from a 2006 Chevy Impala but not 100% certain. They are in overall good condition but not perfect. One of the head rests is missing and a couple of the wire harness have been cut off. The harness are really not a big deal. They most likely would need to be hard wired to fit your application anyway. I did test all the motors and all seemed good. I am pretty sure they are also heated but I have not investigated that part.
