Service bulletin TSB 24-2212

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This article supersedes TSB 24-2168 to address revised software for 2022-2023 HVAC modules. Some 2021-2023 F-150 vehicles equipped with a gasoline, hybrid or flex fuel engine (non-Lightning, non-diesel) may exhibit inoperative A/C, lack of air flow, 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. To correct this condition, follow the Service Procedure to reprogram the PCM and HVAC module to the latest software level via the Ford Diagnosis and Repair System (FDRS)

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
