Official summary
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.
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.
