    Due to part availability, owner letters will be released in phases starting with older model year first. Owners for model year vehicles not included in first phase owner mailing will receive an owner advisory letter.

    The letter will inform the customer that parts are not yet available and that another letter will be sent to them when parts become available. A copy of this letter will be attached to the dealer message announcing this bulletin.

In addition, moisture and other contaminants may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. Either of the above may cause the relay resistor module or wiring connector to overheat, resulting in one or more of the following symptoms:

    - The HVAC blower may not function on certain or all blower speed settings

    Is there a separate fuse for 5? I would check out the fuse panel.

    Next to replacing the Blower Motor Resistor, the Blower Resistor Wiring Connection also should be Replaced,

    This is a Section from the Above G.M. Service Bulletin and it expresses the following.....the interface between the electrical terminals of the relay Resistor Module and the Wiring Connector that powers the module may be incapable of conducting higher current levels for sustained periods of blower motor operation,

    In addition, moisture and other contaminants may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. Either of the above may cause the relay Resistor module or Wiring Connector to Overheat, resulting in one or more of the following symptoms:

    - The HVAC blower may not function on certain or all blower speed settings
    - A burning plastic smell or smoke may be present in the vehicle
    - The HVAC blower may run continually with the ignition in the OFF position
