Some Lincoln MKC owners report experiencing issues with the driver side A/C blowing hot air, which may be attributed to a malfunctioning blend door actuator, refrigerant leak, or faulty compressor. Common causes identified include low or overcharged refrigerant, compressor malfunction, dirty condenser or evaporator coils, and defective sensors or fuses. Some owners have found temporary relief by following a specific reset procedure involving the A/C and rear defrost buttons. However, if the problem persists, it is advisable to consult a professional mechanic or Lincoln dealership for a thorough diagnosis and resolution of the issue.
