Some 2024-2025 F-150 Lightning and 2025 Mustang Mach-E vehicles may exhibit various intermittent inoperative climate control symptoms with diagnostic trouble code (DTC) B1717:06 in the heat pump valve control module (HPVCM).

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
