Was your/her order from Courtesy Nissan also? Same thing happened to me. I ordered it last summer, then let the mirrors sit around for months before I realized that they were both passenger. Courtesy said that they'd get back to me when they could get the right part, but I haven't heard from them in over a month and a half.Well great... she ordered both heated mirrors and received two passenger pieces. So anyway, I got the wiring all squared away and the passenger side works great. Just need to return the extra passenger glass for the drivers side glass.
