Climate control air filter
OIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system. If
dust or other pollutants accumulate in
the filter over a period of time, the air
flow from the air vents may decrease,
resulting in moisture accumulation
on the inside of the windscreen even
when the outside (fresh) air position is
selected.
If this happens, we recommend that the
climate control air filter be replaced by a
HYUNDAI authorised repairer.
