My owners manual warns me to never operate both windows at the same time or risk a blown fuse. Hard to reconcile that with both windows dropping when I unlatch the top though.Me neither. If it is something like auto-opening all windows, we only have 2 windows and if they've been initiated, you simply need to push both window switches down for about 2 seconds, and they will both auto-open.
I'm guessing that one button might auto-open all 4 windows in the Mustang?
Or when lowering the top, all the windows fully open, rather than open halfway like ours do?
I have a feeling your guess is correct. My 2004 Accord had that too. That is the car I traded in for my Spiderthink I might have had this feature in my 2004 Accord. You hold down the unlock button on the key fob and all four windows open. Was great when the car had been in the sun during summer and I needed to vent all that hot air. Our 2013 S60 lacks this feature.
It's kind of a no-brainer for the car company. I don't know why it seems to be such an anomaly.
