SSM 523672024-04-04. Service bulletin. EQUIPMENT; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some 2024 Mustang vehicles built on or before 12-Jan-2024 and equipped with a 2.3L EcoBoost engine may exhibit an inoperative air conditioning system (A/C). This may be due to a refrigerant leak coming from the receiver/drier upper cap on the condenser. If a refrigerant leak is suspected, inspect the receiver/drier upper cap on the condenser for a refrigerant leak. If a refrigerant leak is found, replace the receiver/drier cap and desiccant bag following the Workshop Manual (WSM), Section 412-00. For claiming, use causal part number 19C836 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual. If the receiver/drier upper cap is not leaking, continue with normal diagnostics found in the WSM, Section 412-00.
