Official summary
This Preliminary Information communication provides information to the technician about vehicles that the blower motor may be noisy or vibrate when running. This concern will only occur when the temperatures is below 32 degrees Fahrenheit and if the blower motor is removed while still cold, ice may be found on the blower motor cage. This concern could be caused by water leaking or snow ingestion into the Heater-Vent-Air Conditioning case. Technician is to perform normal water testing diagnostics while the Heater-Vent-Air Conditioning is running, looking for water leaking past the plenum cover.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
