    INSPECT BLOWER RESISTOR


    1. A0156ET

      Measure resistance between terminals 1 and 4.

      Standard Resistance
      2.0 to 2.4 kΩ

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

    2. Inspect blower resistor.


      1. Connect the positive (+) lead to terminal 4 through a 12 V to 3.4 W test bulb and negative (-) lead to terminal 2.

      2. Check the test bulb lights up when another positive (+) lead is connected to terminal 2 through a 12 V to 3.4 W test bulb.

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