2015 JEEP CHEROKEE ac compressor

Mix Mode
Air is directed through the floor, defrost and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort,
while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use the DEFROST mode
with maximum blower and warm temperature settings
for best windshield and side window defrosting.
NOTE:The air conditioning compressor operates in MIX
and DEFROST, or a blend of these modes even if the A/C
button is not pushed. This dehumidifies the air to help
dry the windshield. To improve fuel economy, use these
modes only when necessary.
Recirculation Control
Push this button to choose between outside air intake or
recirculation of the air inside the vehicle. A LED will
illuminate when you are in Recirculation mode. Only use
the Recirculation mode to temporarily block out any
outside odors, smoke, or dust, and to cool the interior
rapidly upon initial start-up in very hot or humid
weather.
NOTE:
•If the RECIRCULATION button is pushed when the
system is in Defrost mode the Recirculation LED
indicator will flash three times and then turn off to
indicate Recirculation mode is not allowed.
•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.

•In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.
•The A/C can be deselected manually without disturb-
ing the mode control selection by pushing the A/C
button.
Air Outlets
The airflow from each of the instrument panel outlets can
be adjusted for direction, and turned on or off to control
airflow.
NOTE:For maximum airflow to the rear, the center
instrument panel outlets can be directed toward the rear
seat passengers.
Economy Mode
If ECONOMY mode is desired, push the A/C button to
turn off the LED indicator and the A/C compressor.
Rotate the temperature control knob to the desired tem-
perature. Also, make sure to select only Panel, Bi-Level or
Floor modes.
Windshield Wiper De-icer — If Equipped
The windshield wiper de-icer is a heating element lo-
cated at the base of the windshield.
The windshield wiper de-icer operates automatically
once the following conditions are met:
•Activation By Front Defrost
The wiper de-icer activates automatically during a cold
weather manual start withfull defrost,theblower speed
is greater than five,and when theambient temperature
is below 40° F (4.4° C).

7. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
and demist outlets. The Mode settings are as follows:
•Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individually
adjusted to direct the flow of air. The air vanes of the
center outlets and outboard outlets can be moved up and
down or side to side to regulate airflow direction. There
is a shut off wheel located below the air vanes to shut off
or adjust the amount of airflow from these outlets.
•Bi-Level Mode
Air comes from the instrument panel outlets and
floor outlets. A slight amount of air is directed
through the defrost and side window demister outlets.
NOTE:BI-LEVEL mode is designed under comfort con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.
•Floor Mode
Air comes from the floor outlets. A slight amount
of air is directed through the defrost and side
window demister outlets.
•Mix Mode
Air comes from the floor, defrost and side window
demist outlets. This mode works best in cold or
snowy conditions.
NOTE:The air conditioning compressor operates in MIX
and DEFROST modes even if the A/C button is not
pushed. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, use these modes only
when necessary.

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes objectionable, increase blower
speed to improve airflow and clearing of the side win-
dows. Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.

WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause the
system to fail, requiring costly repairs. Refer to
Warranty Information Book, located on the DVD,
for further warranty information.
•The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
