Hey everyone. I'm new to this forum and I have a problem with my alarm system. Basically every time I arm my car, it beeps twice and my key fob screams "DOOR OPEN" when clearly no door is open. It is a 350Z and the guy who worked on my car put the "aux" to my windows(I don't know if that has anything to do with it). But someone told me that the problem might be the windows because in a 350Z when you open the door, the window drops a little and when you close the door, the window closes. Does anyone have a solid answer to why there is a malfunction in my system? Thanks!!!
