1999 Mercury Villager climate control

Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
Under normal conditions, your vehicle's climate control system should be
left in any position other than MAX or OFF when the vehicle is parked.
This allows the vehicle to ªbreatheº through the outside air inlet duct.
Prior to turning off the ignition, in snowy or dirty conditions, ensure that
the climate contol system is turned OFF.
²OFF-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to reduce undesirable odors from
entering the vehicle.
²
(Floor and defrost)-Distributes outside air through the
windshield defroster ducts and the front and rear floor ducts. Heating
and air conditioning capabilities are provided in this mode. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the front and rear floor ducts will be slightly warmer than the air sent
to the windshield defroster ducts.
²
(Defrost)-Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
If the temperature is about 4ÉC (40ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
²
(Panel)-Distributes outside air through the instrument panel
registers. Heating and air conditioning capabilities are provided in this
mode. Push the
A/C(A/C) control in order to cool the vehicle below
the outside temperature.
²
(Panel and floor)-Distributes outside air through the instrument
panel registers and the front and rear floor ducts. Heating and air
conditioning capabilities are provided in this mode. Push the
A/C(A/C)
control in order to cool the vehicle below the outside temperature.
For added customer comfort, when the temperature control is
anywhere in between the full hot and full cold, the air distributed
through the front and rear floor ducts will be slightly warmer than the
air sent to the instrument panel registers.
²
(Floor)-Allows for maximum heating by distributing outside air
through the front and rear floor ducts. Heating and air conditioning
capabilities are provided in this mode. Push the
A/C(A/C) control in
order to cool the vehicle below the outside temperature.

Rear seat heating
Rear seat heating is provided through the floor ducts located under the
front seats. Airflow and temperature to the rear seating are regulated by
the main climate control system.
The rear passenger compartment air conditioning system (if equipped)
should be set to OFF, if rear heating is desired.
Operating tips
²In humid weather, select(Defrost) before driving. This will
reduce fogging on your windshield. After a few minutes, select any
desired position.
²To reduce humidity buildup inside the vehicle, don't drive with the
climate control system in the OFF position.
²Don't put objects under the front seat that will interfere with the
airflow to the second row seat floor ducts.

²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield).
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate the air
conditioner as you would normally.
²When placing objects on top of your instrument panel, be careful to
not place them over the defroster outlets. These objects can block
airflow and reduce your ability to see through your windshield. Also,
avoid placing small objects on top of your instrument panel. These
objects can fall down into the defroster outlets and block airflow and
possibly damage your climate control system.
²If the air conditioner works well in MAX A/C, but not in any other
mode when the A/C control is selected, this may indicate that the
passenger compartment odor and particulate air filter (if equipped)
needs to be replaced.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
Rear passenger air conditioning system Ð EATC systems
On vehicles equipped with front passenger EATC systems, the vehicle
will also have rear passenger compartment climate controls, which allow
the rear seat occupants to adjust their air conditioning level.

The odor and particulate air filtration system is designed to reduce the
concentration of objectionable exterior odors as well as airborne particles
such as dust, spores and pollen in the air being supplied to the interior
of the vehicle. The extent of EXTERIOR odor reduction depends on the
odor itself and the perceptional threshold of the individual. The odor and
particulate filtration system gives the following benefits to customers:
²Improves the customer's driving comfort by reducing odor and particle
concentration
²Improves the interior compartment cleanliness
²Protects the climate control components from particle deposits
The filter is located just in front of the windshield under the cowl grille
on the passenger side of the vehicle.
To replace the filter, perform the following procedure:
1. Remove both windshield wiper
arms.
²Lift the wiper arm away from the
windshield surface until the wiper
arm is perpendicular to the
windshield surface.
²Rotate the small retaining clip at
the base of the wiper arm
counterclockwise while holding
the wiper arm.
²Lift and remove the wiper arm
while holding the retaining clip
outward. Note the LH and RH
wiper arms.
