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.
Technicians are to replace the blower motor control module also called the Linear Power Module (LPM) with the P/N listed below. Refer to either the Blower Motor Control Processor Replacement or Blower Motor Processor Replacement-Auxiliary procedures in SI. After replacement of the blower motor control module the customer may notice a slightly higher than expected blower motor speed at any of the blower speed settings.
