Ford Fiesta overheating with A/C blowing hot air on Ford Fiesta

Some Ford Fiesta owners report experiencing overheating issues accompanied by the A/C blowing hot air. These problems can stem from low or overcharged refrigerant in the A/C system, which can prevent proper cooling. Additionally, a malfunctioning compressor may result in hot air being emitted when the vehicle overheats. Owners have also noted that dirty condenser or evaporator coils can hinder A/C performance, leading to similar issues. A faulty blend door actuator is another potential cause, disrupting temperature control within the system. Furthermore, problems with the evaporator temperature sensor or the A/C pressure sensor may contribute to the hot air issue. Lastly, a bad fuse or relay related to the A/C system could also be responsible. It is recommended that affected owners consult a qualified mechanic to diagnose and resolve these concerns effectively.
