ACTUATOR-RECIRCULATION DOOR

The heating-A/C system uses a vacuum operated recirculation door actuator (1) to control the movement of the recirculation-air door within the HVAC air inlet housing.

When vacuum is supplied by the A/C-heater control to the vacuum connector (3) of the recirculation door actuator, the actuator linkage is pulled into the actuator, which moves the recirculation door lever and recirculation-air door to the Recirculation position. The recirculation door actuator is spring loaded, so when vacuum is released from the actuator, the linkage moves the recirculation-air door back to its static position (fresh air).

The recirculation door actuator is retained to the HVAC air inlet housing by an integral mounting provision (2) and can be accessed for service by removing the instrument panel.

The recirculation door actuator cannot be adjusted or repaired must be replaced if found inoperative or damaged.

REMOVAL

WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in an accidental airbag deployment and possible personal injury or death.
