  1. Connect scan tool. Turn ignition on, engine off. Using scan tool, command cooling fan relay on and off. If cooling fan motor follows command, problem is intermittent. If cooling fan motor does not follow command, go to next step.
  2. Remove cooling fan relay. If cooling fan motor runs, repair short to voltage in Light Blue wire between underhood fuse block and cooling fan motor. If fan motor does not run, replace cooling fan relay.
