Some 2024 Mustang vehicles may exhibit a ticking noise coming from the front seats when the heated and cooled seat feature is in use. This may be due to the seat backrest blower motor fan contacting the housing. To correct this condition, replace the front backrest blower motor with the updated version (service part number PU5Z-18D507-B). For claiming, use causal part 18D507 and applicable labor operation in Section 12 of the Service Labor Time Standards (SLTS) Manual.
