Official summary
Some 2021-2023 F-150 vehicles equipped with a gasoline or flex fuel engine (non-Lightning/non-PowerBoost) may exhibit inoperative A/C, lack of air flow, blows warm, and/or evidence of the evaporator freezing. This may be due to the software level of the PCM and heating, ventilation and air conditioning (HVAC) module.
Vehicles covered
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.
