I have disassembled one of these mirrors with the auto dim, signal, puddle light, heat, pwr fold. For a mirror, they are a pain in the ass to replace, but its doable. Be prepared to remove the entire door panel, the foam weather liner, the power controls within the door, a few clips and other wiring harnesses as well as the mirror assembly itself. But as far as replacing or swapping out components within the assembly such as the glass, motor etc, unless you really know how to disassemble plastic and glass parts that have been molded together or adhered with industrial grade adhesive, forget it. You'll end up breaking the plastics within to get at the motor (which might be fine if your just selling the motor until the buyer realizes that is what they have to do and then you no longer have a buyer) and just the glass itself does not come off the plastic backing very easily and I can almost guarantee one would wind up breaking it. Really, in my opinion and from experience, this is one repair where you have to just absorb the cost of a replacement and get rid of the old one. There is little to no value in it if it has broken components within.
