This past weekend it got up to the mid to upper 80's. Since it was so warm, I wanted to roll down the windows of the cars in the driveway to keep things from baking in them. With my 2012 Volt, if I press and hold the unlock button, all the windows will roll down without having to get in the car, power it up and toggle each window down. I tried the same thing with my 2014 Impala 2LTZ. It did not work, is there a way to personalize it so it performs the same function as my Volt on command from the remote? If not, I would think is would be a function of the BCM that does this.
