CLUTCH ASSEMBLY
Removal (Except Grand Cherokee)
Remove compressor shaft bolt. Remove clutch plate and shims.
Tighten a 10-mm bolt into clutch hub bolt hole to remove clutch hub
and shims. Remove snap ring, and remove rotor and pulley assembly.
Remove snap ring, and disconnect clutch coil lead. Remove clutch coil.
Installation
1) Install clutch coil so pin in back of coil aligns with
hole in front compressor housing. Connect clutch coil lead. Install
snap ring with bevel side facing outward. Ensure snap ring is properly
seated in groove. Install rotor and pulley assembly. Install shims and
snap ring. Install clutch hub.
2) Install dial indicator at front of clutch hub to measure
clutch hub air gap. Using battery voltage, energize clutch coil.
Proper air gap is 0.014-0.026" (0.35-0.65 mm). Add or remove shims to
obtain correct air gap. Install compressor shaft bolt. On Concord and
Intrepid, tighten compressor shaft bolt to 11-15 ft. lbs. (15-20 N.m).\
On all other models, tighten compressor shaft bolt to 10 ft. lbs. (14
N.m).
NOTE: On Grand Cherokee, compressor clutch can be serviced in
vehicle without discharging A/C system.
Removal (Grand Cherokee)
Disconnect and isolate negative battery cable. Remove
serpentine drive belt. Remove compressor shaft bolt. Using a plastic
mallet, tap clutch plate to loosen from compressor shaft. Remove
clutch plate, shaft key and shims. See Fig. 5. Remove snap ring, and
remove pulley assembly. Remove snap ring, and disconnect clutch coil
lead. Remove clutch coil.
Installation
1) Install clutch coil so pin in back of coil aligns with
hole in front compressor housing. Connect clutch coil lead. Install
snap ring with bevel side facing outward. Ensure snap ring is properly
seated in groove. Align snap ring eyelets to the left or right of
clutch coil pin. Install rotor and pulley assembly. Install shims and
snap ring. Install clutch hub.
2) Hold clutch plate tight against shims and measure air gap
between clutch plate and pulley face. Air gap should be 0.014-0.026"
(0.35-0.65 mm). Add or remove shims as necessary. Install compressor
shaft bolt. Tighten compressor shaft bolt to 115 INCH lbs. (13 N.m).
To complete installation, reverse removal procedure.
3) After completing compressor clutch installation, start
engine. Set A/C-heater control to recirculated air mode and high
blower motor speed. Set engine speed to 1500-2000 RPM. Cycle
compressor on for 5 seconds and off for 5 seconds, about 20 times to
break-in clutch.
SHAFT SEAL
NOTE: Shaft seal replacement procedure is for 10PA17C compressor.
Shaft seal replacement procedure for 10PA17 compressor is not
available.
Removal
1) Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Remove A/C compressor. Drain oil from
compressor, and measure amount drained. Remove clutch hub, shims,
rotor and pulley assembly, and clutch coil. See CLUTCH ASSEMBLY. See

WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG SYSTEM SAFETY
article.
CAUTION: When battery is disconnected, radio will go into anti-theft
protection mode. Obtain radio anti-theft protection code from
owner prior to servicing vehicle.
DESCRIPTION
These systems are a blend-air type. Outside air enters
through a cowl at base of the windshield and flows through a plenum
chamber into blower housing. Airflow velocity is controlled by blower
speed selector switch. Air flows across evaporator and is directed by
a blend-air door to go either through or by-pass the heater core.
On Dakota and Durango, temperature control cable operates
blend-air door and allows immediate control of outlet air temperature.
It also controls operation of recirculation door. On Ram Pickup,
temperature is regulated by a blend-air servo motor controlled from
A/C-heater control panel rotary temperature dial. On all models, mode
selector switch controls vacuum-operated doors to direct conditioned
air to selected outlets.
Durango may also be equipped with an optional rear A/C unit.
The rear A/C unit consists of a blower motor and evaporator. It will
only operate while the front A/C is on. The optional rear A/C-heater
unit is controlled using fan and temperature switches.

FRICTION MATERIAL
NOTE: Original Equipment Manufacturer (OEM) specifications
designate replacement at different thicknesses.
CAUTION: It is required that friction material be matched in axle
sets for consistent braking characteristics.

Condition Code Procedure
Attaching hardware
broken ................. A ... Require repair or replacement
of hardware.

If equipped, the EMR light (some models may use a reminder
flag) reminds vehicle operator that an emission system maintenance is
required. This indicator is activated after a predetermined
time/mileage.
When performing a smog check inspection, ensure EMR indicator
is not activated. On models using an EMR light, light should glow when
ignition switch is turned to ON position and should turn off when
engine is running.
If an EMR flag is present or an EMR light stays on with
engine running, fail vehicle and service or replace applicable
emission-related components. To reset an EMR indicator, refer to
appropriate MAINTENANCE REMINDER LIGHTS in the MAINTENANCE section.
MALFUNCTION INDICATOR LIGHT (MIL)
The Malfunction Indicator Light (MIL) is used to alert
vehicle operator that the computerized engine control system has
detected a malfunction (when it stays on all the time with engine
running). On some models, the MIL may also be used to display trouble
codes.
As a bulb and system check, malfunction indicator light will
glow when ignition switch is turned to ON position and engine is not
running. When engine is started, light should go out.
