LiamIanto 0 Report post Posted October 9, 2019 Hello. I've recently bought myself a 2004 350z, it seems to be a fairly basic model. The drivers side window has an auto up and down function but the passenger side doesn't, its just one of those creature comforts that I would like to have. Is it as simple as buying a cheap auto switch from china off ebay to add the auto function or is there more to it than that? Like having to change the motor that controls the window and add extra cables to it? Any help is appreciated. Quote Share this post Link to post Share on other sites
