626 (1998)

  1. Locate and remove cooling fan relay to be tested. See COMPONENT LOCATIONS  . Check continuity between cooling fan relay coil terminals ("A" and "B"). See Fig 1 . Continuity should exist. Check continuity between cooling fan relay switched terminals ("C" and "D"). Continuity should not exist. If continuity is as specified, go to next step. If continuity is not as specified, replace cooling fan relay.
  2. Apply battery voltage between cooling fan relay coil terminals ("A" and "B"). With battery voltage applied, continuity should now exist between cooling fan relay switched terminals ("C" and "D"). If continuity is as specified, cooling fan relay is okay at this time. If continuity is not as specified, replace cooling fan relay.
