Had to have a new bed side put on my truck due to a wreck. When I picked it up from the body shop they said the back up camera blew a fuse. Is there an inline fuse? I followed the wire from the camera to the dash, I didn't see one ,then it appears to go up to the d3, what could the problem be?

most camera's do have a fuse, use a meter to check to see if there is voltage on the wires at the camera, also make sure that the reverse wire didnt get unhooked and that the setting is still turned on

What camera are you using?
