#105258, "RE: Automatic Up/Down Windows" In response to In response to 13
I installed the DEI auto-up/down module for that purpose. Way easier than building your own.
I used it with my alarm remote to command windows to vent (2" down during remote start), roll up windows when arming alarm, optional full open when disarming.
Once installed it automatically gave me one-touch up and down on both drivers and passenger windows but only commanded from the drivers switches. The passenger switch still operated as normal.
Some of the window feastures are seen in this video.
