Lexus GX460 air conditioning and heater not functioning, no airflow from fan on Lexus GX460

Some Lexus GX460 owners report experiencing issues with their air conditioning and heater, particularly a lack of airflow from the fan. Common problems include blower motor failures, which can hinder airflow, and thermostat issues that affect heating and cooling functions. Additionally, some owners have encountered refrigerant leaks that lead to inadequate cooling, as well as dirty or clogged components like the cabin air filter and evaporator, which can impair system performance. Electrical system faults, such as a faulty compressor or blend door actuator, may also disrupt the operation of the air conditioning and heating systems. To troubleshoot these issues, some owners check the blower motor for proper functioning, inspect climate controls for accuracy, address refrigerant levels, and verify coolant levels to ensure effective heating. By addressing these concerns, owners can work towards restoring proper functionality and airflow in their Lexus GX460.
