  1. Remove control relay. Relay is located behind left side of dashboard, below instrument cluster.
  2. Apply battery voltage across terminals No. 6 (positive) and No. 8 (negative) while checking voltage on terminals No. 1 and 2. See Fig 1 . Battery voltage should exist. Apply battery voltage across terminals No. 7 (positive) and No. 10 (negative) while checking continuity between terminals No. 3 and 4. Continuity should exist.
  3. Apply battery voltage across terminals No. 3 (positive) and No. 9 (negative) while checking voltage at terminal No. 4. Battery voltage should exist. Replace relay if it fails any test.
