When I use the switch inside. It only cracks it open, if I hold the down button. And if I hit the down button again it will roll all the way down. I checked the track. There isn't anything in the way.
So basically whether I use the key fob (have 2) or the inside down button it only cracks open. If I hit the key down again it does nothing but beep. If I hit the inside down button again it will roll down.
