INTRODUCTION
A design change was made to the blower motor assembly to address the following customer concerns:
- Blower fan is either inoperative or only operates on high speed.
- Excessive rotational-type sound heard when the fan is operating.
An additional ring of material has been added to the housing to protect the connector portion of the assembly from water intrusion and optimize durability.

PART INFORMATION
| Description | Part Number | Applicability |
|---|---|---|
| MOTOR-BLOWER | 72223FJ001 | Manual A/C Models Only |
| RESISTANCE | 72226FG001 | |
| BLOWER & COOLING UNIT | 72210FJ032 | Models w/Auto A/C |
SERVICE PROCEDURE/INFORMATION
- On models equipped with MANUAL A/C:
If the blower fan only operates on high speed, it may be due to an open circuit blower resistor.
Follow the troubleshooting chart located in the "Diagnostics with Phenomenon" section of the applicable Service Manual before replacing any parts. If the resistor is faulty, the damage was most likely a result of increased current draw caused by a seized (binding or loud) blower motor assembly.
Replace the blower motor assembly and resistor as a set following the service procedure in the applicable Service Manual.
- On models equipped with AUTO A/C:
Follow the troubleshooting chart located in the "Diagnostics with Phenomenon" section of the applicable Service Manual before replacing any parts. If the blower motor assembly requires replacement (seized, binding or loud), replace the blower and cooling unit assembly following the service procedure in the applicable Service Manual. If the blower speed cannot be changed normally after replacement, revisit the troubleshooting chart located in the "Diagnostics with Phenomenon" section of the applicable Service Manual.
