Problem overview

Some Lexus ES300h owners report experiencing issues with their air conditioning systems, including the AC not blowing air, which may be due to a refrigerant leak, electrical climate control problems, or a malfunctioning air conditioning compressor. Additionally, some owners find that their AC blows hot air, often caused by low or overcharged refrigerant, compressor failures, dirty condenser or evaporator coils, or problems with the blend door actuator and temperature sensors. Others report inadequate cooling, which can result from similar refrigerant issues, clogged cabin air filters, or a sluggish blower motor. Furthermore, if the AC blower motor is non-functional, it may be linked to a blown fuse, necessitating a check of the fuse box for proper diagnosis and resolution. It is advisable for owners to address these common issues promptly to ensure effective air conditioning performance.
