5-door Except KE Model

1. Turn the ignition switch ON (II) and the heater fan switch ON.

Does the blower run?

YES - Go to step 2.

NO - Go to step 16.

2. Turn the heater fan switch OFF.
3. Make sure the ignition switch is ON (II).

Does the blower motor run?

YES - Go to step 4.

NO -Go to step 9.

4. Turn the ignition switch OFF.
5. Disconnect the blower motor 2P connector.
6. Disconnect the blower resistor 5P connector.
7. Disconnect the heater fan switch 7P connector.
8. Check for continuity between the No. 1, 5, 6 and 7 terminals of the heater fan switch 7P connector and body ground individually.

HEATER FAN SWITCH 7P CONNECTOR

Wire side of female terminals

Is there continuity?

YES - Repair any short to body ground in the wire(s) between the blower motor, the blower resistor and the heater fan switch.

NO - Replace the heater fan switch.

9. Turn the ignition switch OFF.

10. Disconnect the blower resistor 5P connector.
11. Measure the resistance between the No. 1 and No. 5 terminals of the blower resistor.

BLOWER RESISTOR

Is there about 2 - 3 ohm?

YES - Go to step 12.

NO - Replace the blower resistor.

12. Reconnect the blower resistor 5P connector.
13. Disconnect the heater fan switch 7P connector.
14. Turn the ignition switch ON (II).
