Mitsubishi Mirage G4 AC blows hot air at stop but works fine while driving, compressor not functioning after expansion valve replacement and recharge on Mitsubishi Mirage G4

Some Mitsubishi Mirage G4 owners report experiencing issues with their AC blowing hot air while at a stop, despite it functioning properly while driving. This problem may arise from low or overcharged refrigerant levels, which can prevent the AC from cooling effectively. Additionally, a faulty blend door actuator or defective evaporator temperature sensor could also contribute to the issue. Some owners notice that the AC starts off blowing cold air but then turns warm, potentially due to a clogged expansion valve or a malfunctioning compressor clutch. Other factors, such as a clogged expansion valve, blown fuse, or leaks in the system, may also be at play. Furthermore, a defective cooling fan can hinder the AC's performance, as it is essential for dissipating heat from the condenser. It is recommended that owners have their Mitsubishi Mirage G4's AC system inspected by professionals to accurately diagnose and resolve these issues.
