Step 6 - Clip Removal
1. Use a philips-head screwdriver to push inward the pin (at the center of the clip) to a depth of about 2 mm (0.08 in.).
2. Pull the clip outward to remove it.

CAUTION: Do not push the pin inward more than necessary because it may damage the grommet, or the pin may tall in, if pushed too tar.

INSPECTION




BLOWER FAN AND MOTOR CHECK
When battery voltage is applied between the terminals, check that the motor operates. Also, check an abnormal noise.





RESISTOR RESISTANCE CHECK
Use an ohmmeter to measure the resistance between the terminals as indicated below. Check that the measured value is at the standard value.

Standard value:
Measurement terminal = Standard value (Ohms)
Between terminals 3 - 2 (LO) = 1.83
Between terminals 3 - 4 (ML) = 0.87
Between terminals 3 - 1 (MH) = 0.31
