Jeep Liberty KJ. Manual — part 1414
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
negative battery (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 accidental airbag deployment and possible personal injury or
death.
NOTE: The air inlet housing must be removed from HVAC housing and disassembled for service of the
recirculation-air door.

3. Disconnect the HVAC vacuum harness connector
(6) from the recirculation door actuator (5) and if
required, position the vacuum harness (1) out of
the way.
4. Carefully disconnect the recirculation door actuator
from the recirculation door lever (2) and if required,
remove the actuator from the HVAC housing (Refer
