SHAFT SEAL
CAUTION: Secure rear housing to compressor body using a vise before
removing front housing through-bolts. Compressor rear housing
may separate from compressor body, spilling refrigerant oil.
Removal
1) Remove clutch coil. See CLUTCH COIL. See Fig. 1 or 2.
Position compressor in a vise so compressor rear housing is secured to
compressor body. Remove front housing through-bolts and front housing.
2) Using a flat-blade screwdriver, remove felt retainer and
felt from front housing. Remove shaft seal snap ring. Using a flat-
blade screwdriver, remove shaft seal and "O" ring. See Fig. 1 or 2.
Installation
1) Inspect compressor shaft and front housing bore for damage
and/or excessive wear. Ensure "O" ring and shaft seal seat are clean.
Apply NEW refrigerant oil to compressor side of front housing bore.
Lubricate "O" ring and shaft seal with NEW refrigerant oil. Using a
21-mm socket, install shaft seal with "O" ring side facing away from
compressor. Install shaft seal snap ring. See Fig. 1 or 2.
2) Install felt into felt retainer. Using a 14-mm deep
socket, install felt and felt retainer. Lubricate compressor shaft.
Install front housing using care not damage shaft seal lip. See Fig. 1
or 2.
3) Alternately tighten front housing through-bolts to 19 ft.
lbs. (26 N.m). Install clutch plate center bolt. Using an INCH-lb.
torque wrench, ensure compressor breakaway torque is 43 INCH lbs. (4.9
N.m) or less. To complete installation, reverse removal procedures.
Ensure air gap between clutch plate and pulley is correct. See
CLUTCH COIL .

A/C SWITCH
Removal & Installation
Lower glove box. Remove instrument cover. Remove lap cooler
and foot shower ducts. Remove center panel and A/C-heater control
panel. Remove bezel and knob. Disconnect A/C switch connector, and
remove A/C switch. To install, reverse removal procedure.
A/C ENGINE COOLANT TEMPERATURE SWITCH
Removal & Installation
Drain coolant below level of thermostat housing. See Fig. 8.
Remove A/C engine coolant temperature switch wiring harness connector,
and unscrew A/C engine coolant temperature switch from thermostat
housing. To install, reverse removal procedure. Tighten A/C engine
coolant temperature switch to specification. See TORQUE SPECIFICATIONS
. Add coolant and check for leaks.

BLOWER MOTOR & RESISTOR
Removal & Installation
Remove right side foot shower duct. Disconnect blower and/or
resistor. Remove blower motor and/or resistor. See Fig. 9. To install,
reverse removal procedure.

Removal & Installation
Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Disconnect refrigerant temperature
sensor wiring connector. Remove temperature sensor from compressor. To
install, reverse removal procedure. Use new "O" ring on temperature
sensor.

WIRING DIAGRAMS

clockspring, the steering wheel may not turn completely, or
flat cable inside clockspring may be severed, disabling SRS
system and possibly causing serious injury to driver.
Installation
1) Ensure front wheels are in straight-ahead position. Align
mating marks on clockspring. See CLOCKSPRING CENTERING under
ADJUSTMENTS. Install clockspring. To install remaining components,
reverse removal procedure. Before installing air bag module, ensure
horn switch wiring is positioned so that it will not be pinched.
2) Tighten fasteners to spec. See TORQUE SPECIFICATIONS.
Activate SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM . Check AIR BAG
warning light for proper system function. SYSTEM OPERATION CHECK.
PASSENGER-SIDE AIR BAG MODULE
Removal & Installation
1) Before proceeding, see SERVICE PRECAUTIONS. Deactivate
SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Remove right-side foot shower duct and two stoppers on
either side. Remove and lower glove box. Disconnect air bag module
connector. Remove retaining bolts and passenger-side air bag module.
See Fig. 5 .
3) To install, reverse removal procedure. Tighten bolts to
specification. See TORQUE SPECIFICATIONS . Activate SRS. See procedures
under DISABLING & ACTIVATING AIR BAG SYSTEM . Check AIR BAG warning
light for proper system function. SYSTEM OPERATION CHECK.

SRS AIR BAG CONTROL UNIT (ECU)

CAUTION: SRS-ECU connector is a double-locking mechanism. DO NOT use
excessive force when disconnecting connector.
Removal & Installation
1) Before proceeding, see SERVICE PRECAUTIONS. Deactivate
SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Remove rear and front floor console assembly. Remove
switch panel and suspension control switch. Disconnect rear console
harness connector. Remove side panel A and rear console assembly.
3) Remove shift lever. Disconnect front console harness
connector and remove front console assembly. Disconnect SRS-ECU
connector. Remove mounting bolts, bracket and SRS-ECU. See Fig. 6.
