      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Tester Connection Condition Specified Condition
      E21-1 (HI) - E21-4 (E) Always 3.12 to 3.60 Ω
      E21-1 (HI) - E21-2 (M1) Always 1.45 to 1.67 Ω
      E21-1 (HI) - E21-3 (M2) Always 0.52 to 0.60 Ω

      If the resistance is not as specified, replace the blower resistor.
