To put it short i have a 2011 range rover sport, my right front window is having trouble. When i roll the windows down at times it works perfectly and rolls right back up. But for some reason when i try to roll down the window right after it rolls back up it doesn't want to work. I have to wait about 30 seconds before it lets me roll the window back down,not sure if there is not enough power and needs that 30seconds to recharge? Was wondering if has a solution or heard of similar experiences.
