I just bought a used 2008 Titan Crew SE last Wednesday night. I drove it home and the cruise control worded great and for several days later. When I turned the cruise control on yesterday and to set it; it failed to do so. I turned the truck on and off thinking it would reset it but no. When I turn the cruise on the display flashes the words (SET) next the the words cruise. My manual tells me to take it to a Nissan dealer. Does anyone have any ideas why it quit working? Also does anyone know how to fix it? Thanks for any time.
