I am unable to completely recall the details of the different actions for the convenience/comfort feature but I think that "timing" was part of the program. When the vehicle is locked, and the windows/sunroof are open they will close as long as one of the three tumblers is held in the "lock" position. For safety reasons I believe it was programmed to reverse the operation (open the windows) when an "unlock signal" was received within a certain amount of seconds. I do not recall if the windows were capable of rolling down when the "unlock signal" was received after "X" seconds. I do not believe the vehicle can sit for minutes, even hours after it has been locked and than have the windows respond to the unlock signal.

What I find interesting about 400E’s complaint is that the system appears to be operating in reverse, now is it working in reverse from all three points (drivers/passenger/trunk locks) or from just one point, hmm?
