Lexus LS400 air conditioner functioning while heating system fails after new radiator installation on Lexus LS400

Some Lexus LS400 owners report experiencing issues where the air conditioner functions while the heating system fails after installing a new radiator. These problems may stem from a refrigerant leak in the AC system, which can prevent the heating system from operating effectively. Additionally, some owners encounter electrical climate control issues that specifically affect the heating system. Low coolant levels or air trapped in the cooling system can also hinder the performance of the heating system. Furthermore, if the radiator fan is malfunctioning, it can lead to overheating and impact the overall operation of the vehicle's systems, including heating. Lastly, issues with the AC compressor may disrupt the climate control system as a whole. To resolve these concerns, it is advisable for owners to seek a thorough inspection of their vehicle's cooling and climate control systems by a qualified technician.
