I have a 2017 CX-5 GT Premium Pkg. which has auto up/down function on driver's window only. Has anyone done a retrofit with newer OEM switch modules so all four windows are auto up/down? I realize you would have to change not only the master driver's switch, but also the other 3 window switches. The 2020 CX-5 (all trims) has auto up/down on all four windows and I've thought of updating my 2017 GT to have the same functionality. I just don't know if the harnesses and wiring are the same and it's just a simple switch remove/replace job, or if it's more complicated than that.
