Vents and Ducts

The IHKA air distribution system
includes 5 air distribution motors
(stepper motors), right and left footwell
ducts, dashboard mounted defroster
vents, and three sets of face level
vents.
Removal of at least one of the stepper
motors (right footwell vent) involves
removal of the passenger side airbag in
the dashboard.
WARNING!
Airbags are inflated by an explosive
device. Handled improperly or
without adequate safeguards, the
system can be very dangerous.
Special precautions must be
observed prior to any work at or near
the airbags. See
System (SRS).
CAUTION!
When working on interior trim
removal, work with plastic prying
tools or wrap the tips of screwdrivers
and pliers with tape.

Air distribution motors

The five air distribution motors are
installed under the dashboard. They
are made accessible by removing
either the glove compartment and right
footwell trim panel or the left footwell
(pedal cluster) trim panel as described
below.
Each motor can be removed after its
electrical wiring harness connector has
been removed.
