When installing the Dorman 604-624 blend door actuator, ensure the vehicle’s battery is disconnected to prevent electrical shorts. Access to the HVAC housing may require removal of dashboard panels depending on the model. Verify the actuator’s rotary switch aligns correctly with the blend door mechanism before securing. Confirm the two male blade terminals are properly connected to the vehicle’s wiring harness for optimal electrical contact. Testing the actuator operation before reassembling the dashboard is recommended to ensure proper function.
