RECIRCULATION DOOR ACTUATOR (Continued)
The actuator is spring loaded so the door moves to
the outside-air position when no vacuum is supplied
through the electrical solenoid.
The recirculation door actuator can be diagnosed
by performing the ATC Function Test using a
DRBIII
scan tool. Refer to Body Diagnostic Proce-
dures. The recirculation door actuator cannot be
repaired and, if faulty or damaged, it must be
replaced.
