PROBLEM:

INTERMITTENT OPERATION OF THE HEATER BLOWER

The customer will complain that one of the heater blowers is not working and/or that the handbook symbol (
) is illuminated on the ATC message display.

CAUSE:

Poor electrical connection to the inoperative blower motor.

NOTE: If the fault is intermittent and rectifies itself, the
message will remain on the ATC display and the blower will not work until the ignition has been turned off and on.

ACTION:

• = Interrogate the ATC system using TestBook. If the fault is as described above, TestBook will advise that the blower motor is faulty. = • = Prior to changing a blower motor, refer to the following to ensure that the harness connection to the blower motor is secure.

1. Behind the fascia closing panel on the drivers side or the glove box inner on the passenger side, locate the single wire connector to the inoperative blower motor, connector C206 for the LH motor and connector C239 for the RH motor. Refer to Electrical Troubleshooting Manual (ETM) Section Z3, location views 73 and 257, (NOTE: a LHD vehicle is shown in the ETM ).

2. Separate the connector and remove the outer plastic casing. (Do not assume that because the plastic casing is securely latched, that there is good electrical contact ).

3. Compress the female terminal to obtain a secure fit to the male terminal.

4. Reassemble connector.
