Flash: HVAC System Improvements
This bulletin involves updating the HVAC control module with new software. The customer may notice that the blower motor speed may slow down at times. This condition will only happen at mid to high ambient temperatures, 75F (24C) or higher. Also the A/C request may be locked on after a remote start. Only after the vehicle is turned off and restarted, will the customer be able to turn the A/C on or off.
