Some 2022-2023 Transit/E-Transit vehicles built on or before 05-May-2023 may experience an inaccurate air discharge temperature when the electronic automatic temperature control (EATC) is operating in auto or manual mode and the temperature set to 60ðF (15.5ðC) or above. During this condition, the system commands full or mostly heat and the air discharge temperature will only reduce in the LO setting. This may be due to calibration in the heating, ventilation and air conditioning (HVAC) module. To correct this condition, reprogram the HVAC module using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 19980 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
