The main reasons behind air conditioning problems in your 2015 Ford Focus are typically refrigerant leaks, issues with the AC compressor, or problems with the blower motor. Of these, the most frequent culprit is the AC compressor, responsible for circulating refrigerant through the system and transforming low-pressure refrigerant into high-pressure form. A common sign of compressor failure is the emission of warm air from the vents. Additionally, you may hear a squealing or grinding noise from the compressor if it breaks down mechanically. On the other hand, when the blower motor malfunctions, the air conditioner and heater may still function, but you may notice a significant decrease in air pressure, regardless of fan speed or temperature setting.
Air conditioning issues on the 2015 Ford Focus may stem from a refrigerant leak, a faulty AC evaporator, or a malfunctioning AC compressor.
