Dang that makes me a little nervous. My truck is only a couple months old but i have not even opened it once since I’ve had it.Unfortunately, that creates its own problems for us. The F150 moonroof mechanism is very fragile and can easily break when you only use it once or twice a year. I’ve heard other have been popping it to the vent position first, then opening. There’s also some super expensive lubricant you can buy to help keep the mechanism from binding when the moon roof gets sticky.
