I’ve had my 2015 mustang gt for about 6 months now and the passenger window has started to freak out on me. If it’s in the full up position with the door closed it will roll down a 1/4 inch and then back up. It will do it 15-20 times really fast then stop for a while then start again. It even does it with the car off. The only way I could figure out for it to stop is to keep the window cracked 1/4 inch. Just wondering if anyone has ever seen this spooky phenomenon.
