A/C - Erratic Blower Motor Operation

NUMBER: 24-001-05

GROUP: Heating & A/C

DATE: February 1, 2005

THIS BULLETIN IS BEING PROVIDED IN ADVANCE. DO NOT ORDER PARTS OR PERFORM ANY ACTIONS RELATED TO THIS BULLETIN UNTIL FEBRUARY 14, 2005.

SUBJECT:
Blower Motor Does Not Run On Every Speed

OVERVIEW:
This bulletin involves modifying the HVAC housing and installing a revised blower motor resistor.

MODELS:

2000 - 2004 (JR) Sebring Convertible/Sebring Sedan/Stratus Sedan

NOTE:
MODEL YEAR WAS UPDATED FROM 2001-2004 RANGE TO 2000-2004 RANGE PER UPDATE FROM CHRYSLER WEBSITE.



SYMPTOM/CONDITION:

The blower motor does not run on every speed because the blower motor resistor has failed.

DIAGNOSIS:

If the vehicle operator describes the above Symptom, perform the Repair Procedure





PARTS REQUIRED:





SPECIAL TOOLS/EQUIPMENT REQUIRED:

REPAIR PROCEDURE:

WARNING:
On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury or death.

WARNING:
The blower motor resistor may get very hot during normal operation. If the blower motor was turned on prior to servicing the blower motor resistor, wait five minutes to allow the resistor to cool before performing diagnosis or service. Failure to take this precaution can result in personal injury.

1. Disconnect and isolate the negative battery cable.

2. Remove the silencer panel from right side of the instrument panel (Refer to 23 - BODY/INSTRUMENT PANEL/RIGHT IP SILENCER PANEL - REMOVAL).





3. Disconnect the wire harness connector from the blower motor resistor (Fig. 1).

4. Remove the two screws that secure the blower motor resistor to the HVAC housing and remove the resistor.





5. Use a hot knife or similar tool to the enlarge the blower resistor opening in the HVAC housing so that the opening matches the inside edge of raised rib around the opening, (Fig. 2).

NOTE:
Remove any/all debris from the HVAC housing.

6. Position the blower motor resistor into the bottom of the HVAC housing.

7. Install the two screws that secure the blower motor resistor to the HVAC housing. Tighten the screws to 2 Nm (17 in.lbs.).

8. Connect the wire harness connector to the blower motor resistor.

9. Install the silencer panel to the right side of the instrument panel (Refer to 23 - BODY/INSTRUMENT PANEL/RIGHT IP SILENCER PANEL - INSTALLATION).

10. Reconnect the negative battery cable.

11. Set the clock to the correct time.

POLICY:
Reimbursable within the provisions of the warranty.
