Ok, got my eBay RH mirror installed today and it has heat and a puddle lamp. My car already has the signals so I knew that would work. What I know isn't working is the puddle lamp, even though the wiring and fuse appear to be already installed. That was earlier today after FedEx dropped my package off. I will have to get back to you on the heated portion as right now I'm typing this lying in bed with a nasty flu bug.
BTW: The mirror caps come off fairly easy after pulling the glass and disengaging the two retention clips. They're easy to spot at the top of the housing behind the mirror glass.
