INFINITI Q70 actuators failure and intermittent AC/heat issue requiring multiple replacements on INFINITI Q70

Some INFINITI Q70 owners report experiencing actuator failures that lead to issues regulating airflow and temperature within the vehicle's HVAC system. These failures can result in intermittent AC and heat problems, often requiring multiple replacements of components such as the A/C amplifier, blower motor relay, or blend door actuator. Owners have noted that a malfunctioning blend door actuator can cause cold air to flow from one vent while unwanted heat comes from another, leading to inconsistent temperature control. Additionally, improper HVAC system calibration can create temperature disparities between different sides of the vehicle. In cases where heating or cooling works on one side but not the other, replacing components like the blend door actuator or thermostat may be necessary. To accurately diagnose these issues, some owners find it essential to check for refrigerant leaks, assess the compressor, and inspect the climate control panel. Regular maintenance, including filter checks and replacements, is recommended to help prevent airflow and temperature control problems in the INFINITI Q70.
