On certain trucks, the jumper wire between the grid heater relay and the fuse block may have been routed incorrectly during vehicle assembly. If the wire rubs against the radiator support, the chafe point could result in an electrical short, potentially causing a vehicle fire. Correction: Dealers will inspect the routing of the jumper wire; if the wire is not routed correctly, it will be inspected for rubbing or chaffing and replaced if necessary.
