INSPECTION

1. COOLER COMPRESSOR ASSY

  1. Connect the positive (+) lead from the battery to terminal 3 and the negative (−) lead to the body ground.
  2. Check that the magnet clutch energized.

If operation is not as specified, replace the magnet clutch assy.

c. Measure resistance between terminals 1 and 2.

Standard resistance: 165 − 205 W at 20 C (68 F)

If resistance is not as specified, replace the cooler compressor assy.

2. MAGNET−CLUTCH RELAY

If continuity is not as specified, replace the magnet−clutch relay.

If continuity is not as specified, replace the magnet−clutch relay.

3. AIRMIX DAMPER SERVO SUB−ASSY

a. Inspect servomotor operation.

  1. Connect the positive (+) lead from the battery to terminal 4 and negative (−) lead to terminal 5, then check that the arm turns to COLD side smoothly.
  2. Connect the positive (+) lead from the battery to terminal 5 and negative (−) lead to terminal 4, then check that the arm turns to HOT side smoothly.

If operations are not as specified, replace the air mix servomotor.

b. Inspect position sensor resistance.Measure resistance between terminals at servomotor

b. Inspect position sensor resistance.

Measure resistance between terminals at servomotor arm each position as shown in the chart.

If resistance is not as specified, replace the servomotor.

If resistance is not as specified, replace the servomotor.

4. MODE DAMPER SERVO SUB−ASSY

4. MODE DAMPER SERVO SUB−ASSY

a. Inspect servomotor operation.

  1. Connect the positive (+) lead from the battery to terminal 7 and the negative (−) lead to terminal 8.
  2. Connect the negative (−) lead from the battery to each terminal as shown in the chart, and check that the shaft rotates at each position, as shown in the illustration.

If operation is not as specified, replace the servomoto

If operation is not as specified, replace the servomoto

5. RECIRCULATION DAMPER SERVO SUB−ASSY

a. Inspect servomotor operation.

  1. Connect the positive (+) lead from the battery to terminal 5 and negative (−) lead to terminal 1, then check that the arm turns to REC side smoothly.
  2. Connect the positive (+) lead from the battery to terminal 5 and negative (−) lead to terminal 2, then check that the arm turns to FRS side smoothly.

If operations are not as specified, replace the mode damper servomotor.

6. COOLER THERMISTOR No.1

  1. Remove cooler thermistor No.1.
  2. Check resistance between terminals 1 and 2 of cooler thermistor No.1 at each temperature, as shown in the chart.

Standard:

NOTICE:

NOTICE: Even slightly touching the sensor may change the resistance value.Be sure to hold the connector of the sensor.

HINT: As the temperature increases, the resistance decreases (see the chart below).

7. BLOWER W/FAN MOTOR SUB−ASSY

7. BLOWER W/FAN MOTOR SUB−ASSY

a. Connect the positive (+) lead from the battery to terminal 2 and negative (−) to terminal 1, then check that the motor operation smoothly.

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

8. BLOWER RESISTOR

a. Measure resistance between terminals, as shown in the chart below.

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

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