      *1 A/C Switch
      *a

      Component without harness connected

      (No. 1 Heater Control Sub-assembly)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      2 (L) - 3 (E) Always 10 kΩ or higher
      2 (L) - 4 (B) A/C switch ON Below 1 Ω
      2 (L) - 4 (B) A/C switch OFF 10 kΩ or higher
      3 (E) - 4 (B) Always 10 kΩ or higher
      5 (ILL+) - 6 (ILL-) Always Below 1 Ω

      • If the result is not as specified, replace the heater control sub-assembly.

    2. Check the A/C indicator operation.


      1. Connect the positive (+) lead from the battery to terminal 2 (L) and the negative (-) lead to terminal 3 (E).

      2. Push the A/C switch in and check that the indicator lights up.

        OK
        Indicator lights up

        • If the result is not as specified, replace the heater control sub-assembly.

    3. Check the illumination operation.


      1. Connect the positive (+) lead from the battery to terminal 5 (ILL+) and the negative (-) lead to terminal 6 (ILL-), then check that the bulb illuminates.

        OK
        Bulb illuminates

        • If the result is not as specified, replace the bulb.

  2. INSPECT NO. 2 HEATER CONTROL SUB-ASSEMBLY

      *a off
      *b lo
      *c M1
      *d M2
      *e HI
      *f

      Component without harness connected

      (No. 2 Heater Control Sub-assembly)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      ALL - 5 (E) 0 (OFF) 10 kΩ or higher
      9 (LO) - 5 (E) 1 (LO) Below 1 Ω
      9 (LO) - 5 (E) - 7 (M1) 1 (LO) - 2 (M1) Below 1 Ω
      9 (LO) - 5 (E) - 7 (M1) 2 (M1) Below 1 Ω
      9 (LO) - 5 (E) - 7 (M1) - 6 (M2) 2 (M1) - 3 (M2) Below 1 Ω
      9 (LO) - 5 (E) - 6 (M2) 3 (M2) Below 1 Ω
      9 (LO) - 5 (E) - 10 (HI) - 6 (M2) 3 (M2) - 4(HI) Below 1 Ω
      9 (LO) - 5 (E) - 10 (HI) 4 (HI) Below 1 Ω

      • If the result is not as specified, replace the No. 2 heater control sub-assembly.

    2. Check the illumination operation.


      1. Connect the positive (+) lead from the battery to terminal 2 (ILL+) and the negative (-) lead to terminal 1 (ILL-), then check that the bulb illuminates.

        OK
        Bulb illuminates

        • If the result is not as specified, replace the bulb.

  3. INSPECT NO. 3 HEATER CONTROL SUB-ASSEMBLY


    1. A005M4PE02
      Text in Illustration
      *1 Rr Defogger Switch
      *a MAX HOT
      *b

      Component without harness connected

      (No. 3 Heater Control Sub-assembly)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      2 (Rr DEF) - 1(E) Rear window defogger switch ON Below 1 Ω
      Rear window defogger switch OFF 10 kΩ or higher
      3 (IG) - 6 (MAX-HOT) MAX HOT Below 1 Ω
      Except MAX HOT 10 kΩ or higher
      7 (V/B) - 8 (SG) Always Below 1 Ω

      • If the result is not as specified, replace the No. 3 heater control sub-assembly.

    2. Check the rear window defogger indicator operation.


      1. Connect the positive (+) lead from the battery to terminal 3 (IG) and the negative (-) lead to terminal 1 (E).

      2. Push the rear window defogger switch in and check that the indicator lights up.

        OK
        Indicator lights up

        • If the result is not as specified, replace the No. 3 heater control sub-assembly.

    3. Check the illumination operation.


      1. Connect the positive (+) lead from the battery to terminal 5 (ILL+) and the negative (-) lead to terminal 4 (ILL-), and then check that the bulb illuminates.

        OK
        Bulb illuminates

        • If the result is not as specified, replace the bulb.
