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

        Standard Resistance
        Tester Connection Condition Specified Condition
        3 (FRS) - 4 (REC) Recirculation/fresh switch: OFF Below 1 Ω
        3 (FRS) - 4 (REC) Recirculation/fresh switch: ON 10 kΩ or higher
        5 (LED+) - 4 (REC) Recirculation/fresh switch: OFF 10 kΩ or higher
        5 (LED+) - 4 (REC) Recirculation/fresh switch: ON Below 1 Ω

        • If the result is not as specified, replace the No. 1 heater control sub-assembly.

    2. Check the indicator light.


      1. Turn the recirculation/fresh switch to the on position.

      2. Connect a positive (+) lead from the battery to terminal 2 (A/C+) and negative (-) lead to terminal 4 (REC), and check that the indicator light comes on.

        OK
        The indicator light comes on.

        • If the result is not as specified, replace the No. 1 heater control sub-assembly.

    3. Check that the illumination light.


      1. Connect a positive (+) lead from the battery to terminal 7 (ILL+) and negative (-) lead to terminal 6 (ILL-), and check that the illumination light.

        OK
        The illumination light comes on.

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

  2. INSPECT NO. 2 HEATER CONTROL SUB-ASSEMBLY


    1. Measure the resistance.


      1. A01T8DVC03

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (LO), 6 (HI), 8 (M1), 10 (M2) - 5 (E) Blower switch: OFF 10 kΩ or higher
        1 (LO) - 5 (E) Blower switch: LO Below 1 Ω
        1 (LO), 8 (M1) - 5 (E) Blower switch: LO - M1 Below 1 Ω
        1 (LO), 8 (M1) - 5 (E) Blower switch: M1 Below 1 Ω
        1 (LO), 8 (M1), 10 (M2) - 5 (E) Blower switch: M1 - M2 Below 1 Ω
        1 (LO), 10 (M2) - 5 (E) Blower switch: M2 Below 1 Ω
        1 (LO), 10 (M2), 6 (HI) - 5 (E) Blower switch: M2 - HI Below 1 Ω
        1 (LO), 6 (HI) - 5 (E) Blower switch: HI Below 1 Ω
        2 (RDEF) - 5 (E) Rear window defogger switch: OFF 10 kΩ or higher
        2 (RDEF) - 5 (E) Rear window defogger switch: ON Below 1 Ω

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

    2. Check that the rear window defogger switch indicator light.


      1. Connect a positive (+) lead from the battery to terminal 4 (IG+) and the negative (-) lead to terminal 5 (E).

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

        OK
        The indicator light comes on.

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

    3. Check that the illumination light.


      1. Connect a positive (+) lead from the battery to terminal 9 (ILL+) and negative (-) lead to terminal 7 (ILL-), and check that the illumination light.

        OK
        The illumination light comes on.

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