Mercury Villager 2002 s Repair Manual

REAR PASSENGER AIR CONDITIONING SYSTEM (IF EQUIPPED)
This system allows the rear seat occupants to adjust their air
conditioning comfort level.
The rear A/C fan speed control allows the rear passengers to control the
volume of air that is distributed from the rear registers.
The rear seat A/C system is controlled from the main climate control
system on the instrument panel. Ensure that the control is set to REAR
A/C to engage the rear passenger compartment air conditioning system.

Turning the Rear A/C on
1. Set the main climate control rear fan control to Rear A/C; set the
mode selector to any position (other than OFF), and depress the A/C
control.
2. Set the fan speed on the Rear A/C fan control to a number between
1–4 to regulate the airflow to the rear seat section.
The Rear A/C fan speed may be adjusted by the front seat passengers.
For example, if the Rear A/C fan speed is set at 4, the Rear A/C control
on the main climate control system may be adjusted to a lower setting
and will override that of the rear seat setting.
Turning the Rear A/C off:
There are two ways to turn the rear air conditioning system off. The first
way is to set the Rear Fan Control on the main climate control system to
OFF.

switch to the OFF (0) position.
Please note that the rear passenger air conditioning system is
designed for air conditioning purposes only, and does not heat the
rear compartment. Rear compartment heating is provided by the
underseat floor ducts. Refer to Rear Seat Heating.
ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM (IF EQUIPPED)
The EATC system will maintain a selected temperature and automatically
control airflow. You can override automatic operation with any of the
override controls or the fan speed control.

Turning the EATC system on
Press AUTOMATIC, any of the override controls or the fan speed control.
The EATC system will only operate when the vehicle is running.
Turning the EATC system off
Press OFF.
Automatic operation
Press AUTOMATIC and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC system will either heat or cool to achieve the selected
temperature. The system will automatically determine fan speed, airflow
location and if outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed thumbwheel is turned or the
steering wheel fan speed control (if equipped) is pressed.
When in AUTOMATIC and weather conditions require heat, air will be
sent to the floor. However, if the engine is not warm enough to provide
heat, the fan will be at a low speed and the air will be directed to the
windshield. In approximately 3
1⁄2minutes or less, the fan speed will start
to increase and the airflow location will change to the floor area.

If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations and the fan control
allows you to adjust fan speed as necessary.
Temperature selection
The display window indicates the
selected temperature, function
(AUTO or one of the override
controls) and manual control of fan
speed (
) if automatic fan speed is not desired.
To control the temperature, select
any temperature between 15°C
(60°F) and 32°C (90°F) by pressing
the temperature controls. However,
individual temperature settings
between 15°C (60°F) and 18°C
(65°F) cannot be selected. The 15°C
(60°F) and 18°C (65°F)
temperatures are the lowest settings
available.
For continuous maximum cooling, push the temperature control until
15°C (60°F) is shown in the display window. The EATC will continue
maximum cooling (disregarding the displayed temperature) until a
warmer temperature is selected by pressing the temperature controls.
For continuous maximum heating, push the temperature controls until
32°C (90°F) is shown in the display window. The EATC will continue
maximum heating (disregarding the displayed temperature) until a
cooler temperature is selected by pressing the temperature control.
Fan speed (
)
When AUTOMATIC is pressed, fan
speed is adjusted automatically for
existing conditions. You can override
fan speed at any time. To control
fan speed manually, use the
thumbwheel to cancel automatic fan
speed operation. Rotate the
thumbwheel or press the steering
wheel controls (if equipped) up for
higher fan speed or down for lower
fan speed.

To return to automatic fan operation, press AUTOMATIC.
Manual override controls
The override controls allow you to:
•manually control where the airflow is directed
•manually control the air conditioning operation
•manually select between outside or recirculated air during air
conditioning operation
The air conditioning can operate in all modes except OFF. It will also
operate only when required when AUTOMATIC has been selected.
However, the air conditioning will only function if the outside
temperature is about 4°C (40°F) or higher.
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.
•OFF-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.
•
(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.

•(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 4°C (40°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
•
(Panel) - Distributes outside air through the instrument panel
registers. Heating and air conditioning capabilities are provided in this
mode. Push
A/Cto cool the vehicle below the outside temperature.
•
(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
A/Cto 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

•
(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
A/Cto cool the vehicle
below the outside temperature.
•MAX A/C - Uses recirculated air to cool the vehicle. MAX A/C is
noisier than
A/CA/C but more economical and will cool the inside of
the vehicle faster. After pressing the MAX control, both the MAX
and
A/CA/C indicators will light and the airflow will be from the
instrument panel registers. In this mode, the air conditioning will
automatically engage if the outside temperature is about 4°C (40°F) or
higher.
Cooling your vehicle with outside air using override controls
Cooling your vehicle with air conditioned outside air using just the A/C
override control is quieter but less economical than using both the A/C
and the MAX control. It also has less cooling capacity and is not
recommended for high outside temperatures.
In order to cool your vehicle with outside air using the override controls:
1. Select the override control
,or.
2. Press
A/C. The indicator light onA/Cwill illuminate.
3. Select the desired temperature for your comfort level.
4. Adjust the fan speed override knob to the position of your choice.

During periods of high humidity, vapor may be emitted from the air
outlets when using the A/C system with outside air. This can be
corrected by using MAX A/C to cool the vehicle.
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.
Operating tips
•In humid weather, select
(Defrost) before driving. This will
reduce fogging on your windshield. Once the windshield has been
cleared, operate the climate control system as desired.
•To reduce humidity buildup inside the vehicle in cold weather
conditions, do not drive with the climate control system in the OFF or
MAX A/C position.
•To reduce humidity buildup inside the vehicle in warm weather
conditions, do not drive with the climate control system in the OFF
position.
•Under normal weather conditions, your vehicle’s climate control
system should be left in any position other than MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to“breathe”
through the outside air inlet duct.
•Under snowy or dirty weather conditions, your vehicle’s climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
•If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been“aired out”, operate the climate
control system as desired.

•Do not place objects under the front seat that will interfere with the
airflow to the rear seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•Do not place objects over the defroster outlets. These objects may
block airflow and reduce visibility through your windshield. Avoid
placing small objects on top of your instrument panel. These objects
can fall down into the defroster outlets and block airflow, in addition
to, damaging the climate control system.
To aid in defogging/demisting in cold weather conditions:
1. Select
.
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. Direct the outer panel vents towards the side windows
To increase airflow to the outer panel vents, close the central panel
vents.
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—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.
Climate Controls
