Some customers may comment that the blower motor is inoperative or continues to run after the vehicle has been shut off.
These conditions may be caused by a blower motor control module failure. This failure may occur when the vehicle is operated in ambient temperature conditions of-23°C (-10°F) or below.
Replace the blower motor control module if the vehicle experienced a blower motor control module failure in extremely cold ambient temperature conditions.

Refer to either the Blower Motor Control Processor Replacement or Blower Motor Processor Replacement-Auxiliary procedures in SI.
