There are two ways to close the Truxedo cover: manually or with the remote. To close the cover manually, open the cover all the way and then pull it towards the cab of the truck. On the other hand, to close and open the cover with the remote, press the "close" or "open" button and hold it down. The cover will close or open automatically. If the cover does not close or open automatically, then there may be something blocking it. Check the area around the cover for any obstructions and remove them. Besides, if you still facing a problem, then Contact Truxedo customer service for assistance.
