Ford Transit-350 vent temperature control mismatch with 120-degree air despite 60-degree setting, awaiting factory response on Ford Transit-350

Some Ford Transit-350 owners report experiencing a significant mismatch between the set temperature and the actual air output, with instances of 120-degree air being emitted despite settings adjusted to 60 degrees. This issue may be indicative of poor air conditioning performance, which has been noted in Ford Transit models from 2015 to 2019, potentially due to refrigerant leaks from the evaporator. Owners facing these problems are advised to consider replacing only the evaporator case instead of the entire climate control housing assembly. To effectively address the temperature control mismatch, it is recommended that owners seek inspection and diagnosis from a certified Ford technician.
