The housing on the right side mirror on my 2009 silver Prius is cracked (photo attached) I'm trying to find out: Is there's a sub-assembly that would be used to fix this, or do I need to get a whole new mirror assembly? If I need to get the whole assembly, how can I tell if a used one is heated or unheated? Mine is unheated, and I found a used one, but the seller doesn't know if it's heated or unheated. Can I tell from the connector, or is there additional wiring apart from the connector if it is a heated assembly? Thanks!
The damage looks very minor, I think you should leave it as is. The mirrors are ALL heated from GenII Prius, has nothing to do with the housing.
